Technologies develops and offers strategy trading software tools and subscription services. The Company also has a United Kingdom subsidiary, TradeStation Europe Limited, which is currently in its start-up phase.

The accompanying consolidated financial statements include the results of the Company and its subsidiaries, all of which are wholly owned. All
intercompany accounts and transactions have been eliminated.

The accompanying consolidated financial statements should be read in
conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K of TradeStation Group for the year ended December 31, 2005. In the opinion of management, all
adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Companys consolidated financial position as of March 31, 2006 and the consolidated results of operations and cash flows for each of the periods
presented have been recorded. The results of operations and cash flows for an interim period are not necessarily indicative of the results of operations or cash flows that may be reported for the year or for any subsequent period.

Recently Issued Accounting Standards

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), Share-Based Payment(SFAS No. 123R), effective January 1, 2006. SFAS 123R, which is a revision of
SFAS No. 123, Accounting for Stock-Based Compensation, supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, Statement of Cash Flows. SFAS No. 123R requires all
share-based payments to employees, including grants of employee stock options, to be recognized in the statement of income based on their fair values. Pro forma disclosure is no longer an alternative. The Company has adopted the fair value
provisions of SFAS No. 123R using the modified-prospective-transition method. Under the modified-prospective-transition method of adoption, compensation cost is recognized for all stock-based awards issued after the effective date, and for the
portion of outstanding awards for which the requisite service has not yet been rendered (i.e., stock-based awards granted prior to the effective date, but not yet vested as of the effective date). Under this method of transition, results for prior
periods are not restated. During the three months ended March 31, 2006, the adoption of SFAS 123R resulted in $400,000 of stock-based compensation included in employee compensation and benefits in the Companys consolidated statement of
income. Accordingly, the Companys income before income taxes and net income for the three months ended March 31, 2006 were $400,000 and $379,000, respectively, lower than they would have been if the Company had continued to account for
share-based compensation under APB Opinion No. 25. If the Company had not adopted SFAS 123R, basic and diluted earnings per share for the three months ended March 31, 2006 would have been $0.17 and $0.16, respectively, as compared to the
reported basic and diluted earnings per share of $0.16 and $0.15, respectively.

SFAS No. 123R also requires the benefits of tax
deductions in excess of recognized compensation costs to be reported as a financing cash flow, rather than as an operating cash flow as required under the previous literature. This requirement reduced net operating cash flows and increased net
financing cash flows by approximately $1.2 million during the three months ended March 31, 2006. See Note 2 

STOCK-BASED COMPENSATION for further information regarding the Companys stock-based compensation assumptions and
expenses, including pro forma disclosures for prior periods as if we had recorded stock-based compensation expenses.

The Company adopted
SFAS No. 154, Accounting Changes and Error Corrections, effective January 1, 2006. SFAS No. 154, which is a replacement of APB Opinion No. 20, Accounting Changes and SFAS No. 3, Reporting Accounting Changes
in Interim Financial Statements, provides guidance on accounting for and reporting of accounting changes and error corrections. It requires a voluntary change in accounting principle to be applied retrospectively to all prior periods
financial statements as if the principle had always been applied. Previously, voluntary changes in accounting principles were required to be recognized by including the cumulative effect of changing to the new accounting principle in net income
during the period of change. The adoption of SFAS No. 154 did not have any impact on the Companys consolidated financial position, results of operations or cash flows.

(2) STOCK-BASED COMPENSATION

The Company believes that stock-based compensation is an integral way
to provide incentives which will attract and retain highly-competent persons at all levels of the Company, as independent directors, and as independent contractors providing consulting or advisory services to the Company, by providing them
opportunities to acquire the Companys common stock or to receive monetary payments based on the value of such shares.

Stock Plans

The Company has reserved 7.5 million shares of its common stock for issuance under the TradeStation Group Incentive Stock Plan
(the Incentive Stock Plan). The Companys Board of Directors has authorized an increase in the number of shares to 12.0 million, as well as an extension of the expiration date of the Incentive Stock Plan from June 29, 2006
until June 5, 2016, subject to obtaining shareholder approval at the annual meeting of the Companys shareholders on June 6, 2006. Under the Incentive Stock Plan, incentive and nonqualified stock options, stock appreciation rights,
stock awards, performance shares and performance units are available to employees or consultants. Currently, only stock options have been granted. The terms of each option agreement are determined by the Compensation Committee of the Board of
Directors. Options are generally granted by the Company at an exercise price equal to the fair value (as defined in the Incentive Stock Plan) at the date of grant, vest over a period of 5 years, and expire 10 years after the grant date. On
October 25, 2005, the Company (i) globally amended the terms of all outstanding stock option agreements pursuant to the Incentive Stock Plan for non-executive employees, and (ii) adopted a new form of stock option agreement for future
grants to non-executive employees, in each case, to provide for the accelerated vesting of all unvested options in the event the Company undergoes a change in control and the optionees employment is terminated by the Company (or its successor)
without cause within one year following the change in control. This change did not result in any additional compensation expense during 2005, as the employees did not receive any additional benefits as a result of the change and the unvested options
continued to vest as employees continued to provide services to the Company.

In connection with the 2000 merger of TradeStation
Technologies (formerly known as Omega Research, Inc.) and TradeStation Securities (formerly known as onlinetradinginc.com corp.), the Company assumed the outstanding options under TradeStation Securities 1999 Stock Option Plan. Those options
generally vested ratably over a five-year period and their terms are ten years. As part of the 1999 acquisition of Window on WallStreet, the Company assumed all outstanding stock options to purchase Window On WallStreet common stock. Those options
generally vested ratably over a four-year period and their terms are ten years.

The Company has reserved 350,000 shares of its common
stock for issuance under the TradeStation Group Amended and Restated Nonemployee Director Stock Option Plan (the Director Plan). Under the Director Plan, an independent director is awarded an initial grant of up to 75,000 non-qualified
stock options and annual grants of 7,000 non-qualified stock options. The terms of each option grant are

determined by the Board of Directors. Options under this plan are generally granted by the Company at an exercise price
equal to the fair value (as defined in the Director Plan) at the date of grant, vest over a period of three years, and expire five years after the grant date.

See General Stock Option Information below for additional information about options outstanding as of March 31, 2006.

Employee Stock Purchase Plan

The Company has reserved 500,000 shares of common stock for issuance
under the TradeStation Group Employee Stock Purchase Plan (the Purchase Plan). Under the Purchase Plan, participating employees may purchase common stock through accumulated payroll deductions. Effective with the offering period
beginning January 3, 2006, the Purchase Plan was amended so that the exercise price for the options for each six-month Purchase Plan period is equal to 85% of the fair market value of the Companys common stock on the exercise date (i.e.,
the end of the six-month period). At March 31, 2006, there were 253,845 shares available for future grants under the Purchase Plan. The Company did not issue any shares under this plan during the three months ended March 31, 2006.

Stock Compensation

In
accordance with SFAS No. 123, Accounting for Stock-Based Compensation, in accounting for stock-based transactions with non-employees the Company records compensation expense in the statement of income when such equity instruments are
issued. There were no stock-based transactions with non-employees during the three months ended March 31, 2006 or 2005; therefore, no such compensation expense was recorded.

As permitted by SFAS No. 123, prior to January 1, 2006, the Company accounted for its stock-based payments to employees using the intrinsic
value method in accordance with the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and recognized no compensation cost for employee stock options because options granted under the
Companys plans have had an exercise price equal to the fair value of the underlying common stock on the date of grant. Effective January 1, 2006, the company adopted the fair value recognition provisions of SFAS 123R using the
modified-prospective-transition method. Under the modified-prospective-transition method of adoption, compensation cost is recognized for all stock-based awards issued after the effective date, and for the portion of outstanding awards for which the
requisite service has not yet been rendered (i.e., stock-based awards granted prior to the effective date, but not yet vested as of the effective date). Under this method of transition, results for prior periods are not restated.

The Company currently uses the Black-Scholes option pricing model to determine the fair value of stock option awards. The determination of the fair value
of stock-based awards on the date of grant using an option-pricing model is affected by the market price of our stock, exercise price of an award, expected term of award, volatility of our stock over the term of the award, risk-free interest rate
and expected dividend yield. Separate assumptions are used for employee options (which vest over a five-year period) and non-employee director options (which vest over a three-year period).

For employee stock option awards, the expected term of all options granted is estimated by taking a weighted average of the following factors:
(i) historical holding term from grant date to exercise date; (ii) the historical holding term from grant date to post-vest cancellation date, and (iii) the projected term for the outstanding options based on a midpoint scenario
whereby all vested options would be exercised midway between the valuation date and the contractual term. For non-employee director option grants, the expected term is estimated by taking the average of the weighted average vesting term and the
contractual term, as illustrated in the SEC Staff Accounting Bulletin 107. The expected volatility assumptions are based upon a cumulative look-back of historical volatility calculated on an average of the high and low stock price on a daily basis
over the expected term of an award. The risk-free interest rate that is used in the option valuation model is based upon the U.S. Treasury note yields with a remaining term similar to the expected term of the particular options awarded. The Company
does not anticipate paying any cash dividends in the foreseeable future and, therefore, an expected dividend yield of zero is used in the valuation model.

##### Table of Contents

In accordance with SFAS 123R, the Company is required to estimate forfeitures at the time of grant and
revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data to estimate pre-vesting option forfeitures is used, and stock-based compensation expense is recorded only for those awards that are
expected to vest. Estimated forfeitures were not used in our expense calculation for prior year pro forma footnote disclosure. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards,
which are generally the vesting periods.

The assumptions used to estimate the fair value of each option grant on the date of grant using
the Black-Scholes model is as follows:

During the three months ended March 31, 2006, the adoption of SFAS 123R resulted in $400,000
of stock-based compensation included in employee compensation and benefits in the Companys consolidated statement of income. Accordingly, the Companys income before income taxes and net income for the three months ended March 31,
2006 were $400,000 and $379,000, respectively, lower than they would have been if the Company had continued to account for share-based compensation under APB Opinion No. 25. If the Company had not adopted SFAS 123R, basic and diluted earnings
per share for three months ended March 31, 2006 would have been $0.17 and $0.16, respectively, as compared to the reported basic and diluted earnings per share of $0.16 and $0.15, respectively.

Effective January 1, 2006, in accordance with SFAS No. 123R, the Company has recorded stock-based compensation (included in the $400,000
discussed above) related to the Purchase Plan. The amount of compensation expense is the difference between the fair value of the stock to be purchased and the purchase price of the stock (i.e., the expense recorded is equal to the 15% discount).
The stock-based compensation related to the Purchase Plan is recognized ratably over the six-month purchase period and recognized, along with any payroll withholdings, as a liability on the consolidated balance sheet.

The following table illustrates the pro forma effect on net income and earnings per share for the three months ended March 31, 2005, as if the
Company had applied the fair value recognition provisions of SFAS No. 123 to stock-based employee transactions.

##### Table of Contents

Prior to the adoption of SFAS 123R, the Company presented all benefits of tax deductions resulting from
the exercise of stock options as operating cash flows in the statement of cash flows. SFAS No. 123R requires the benefits of tax deductions in excess of recognized compensation costs to be reported as a financing cash flow, rather than as an
operating cash flow as required under the previous literature. This requirement reduced net operating cash flows and increased net financing cash flows by approximately $1.2 million during the three months ended March 31, 2006.

As of March 31, 2006, there was approximately $6.0 million of unrecognized compensation cost, adjusted for estimated forfeitures, related to
non-vested stock-based payments granted to the Companys employees and non-employee directors. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures, and is expected to be recognized over 3.7 years.

The total intrinsic value of options exercised during the three months ended March 31, 2006
and 2005 was approximately $3.8 million and $269,000, respectively. This intrinsic value represents the difference between the fair market value of the Companys common stock on the date of exercise and the exercise price of each option. During
the three months ended March 31, 2006 and 2005, the benefit of tax deductions in excess of recognized compensation costs (realized through additional paid-in capital) from stock option exercises was approximately $1.2 million and $104,000,
respectively. During the three months ended March 31, 2006, the benefits of tax deductions recognized through income were approximately $6,000.

Upon the exercise of stock options, the Company issues new shares of common stock from its shares authorized and available for issuance.

A summary of changes in unvested options in the Companys stock option plans for the three months ended March 31, 2006 is as follows:

(3) EARNINGS PER SHARE

Weighted average shares outstanding for the three months ended March 31, 2006 and 2005 are calculated as follows:



|                                                                          |  |                                      |  |

Stock options outstanding for the three months ended March 31, 2006 and 2005, which were not
included in the calculation of diluted earnings per share because their weighted average effect would have been anti-dilutive, were approximately 242,000 and 1.9 million, respectively.

(4) COMPREHENSIVE INCOME

Comprehensive income is
defined as the change in a business enterprises equity during a period arising from transactions, events or circumstances relating to non-owner sources, such as unrealized gains or losses on available-for-sale securities and foreign currency
translation adjustments. It includes all changes in equity during a period except those resulting from investments by, or distributions to, owners. A reconciliation of net income to comprehensive income is as follows:

(5) CASH SEGREGATED IN COMPLIANCE WITH FEDERAL REGULATIONS

Cash segregated in compliance with federal regulations, consisting primarily of interest-bearing cash deposits of $452.1 million and $426.1 million as of
March 31, 2006 and December 31, 2005, respectively, have been segregated in special reserve bank accounts at JPMorgan Chase Bank, N.A. or one of its banking affiliates for the exclusive benefit of customers under Rule 15c3-3 of the
Securities Exchange Act of 1934 and other regulations. On the second business day of each month, if required, this amount is adjusted based upon the month-end calculation. On April 4, 2006, cash segregated in compliance with federal regulations
was decreased by $18.4 million, from $452.1 million (the balance as of March 31, 2006) to $433.7 million. Conversely, cash and cash equivalents was increased by $18.4 million, from $60.8 million (the balance as of March 31, 2006) to $79.2
million. On January 4, 2006, cash segregated in compliance with federal regulations was increased by $9.5 million, from $426.1 million (the balance as of December 31, 2005) to $435.6 million. Conversely, cash and cash equivalents was
decreased by $9.5 million, from $75.1 million (the balance as of December 31, 2005) to $65.6 million.

(6) RECEIVABLES FROM BROKERAGE CUSTOMERS,
NET

Receivables from brokerage customers, net, consist primarily of margin loans to TradeStation Securities brokerage customers
of approximately $70.1 million at March 31, 2006 and approximately $58.1 million (net of a $226,000 allowance for a potential credit loss) at December 31, 2005. During the three months ended March 31, 2006, the Company collected
$200,000 of a previously fully-reserved

##### Table of Contents

receivable. Securities owned by brokerage customers are held as collateral for margin loans. Such collateral is not
reflected in the consolidated financial statements. At March 31, 2006 and December 31, 2005, TradeStation Securities was charging a base margin debit interest rate of 8.125% per annum on debit balances in equities brokerage customer
accounts.

Margin requirements determine the amount of equity required to be held in an account for the purchase of equities on
credit. Margin lending is subject to the margin rules of the Board of Governors of the Federal Reserve System, the margin requirements of the NASD, limits imposed by clearing agent firms, and TradeStation Securities own internal policies. By
permitting customers to purchase and maintain securities positions on margin, TradeStation Securities takes the risk that a market decline will reduce the value of the collateral securing its margin loan to an amount that renders the margin loan
unsecured. Under applicable securities laws and regulations, once a margin account has been established, TradeStation Securities is obligated to require from the customer initial margin of no lower than 50% for purchases of securities and then is
obligated to require the customer to maintain its equity in the account equal to at least 25% of the value of the securities in the account. However, TradeStation Securities current internal requirement is that the customers equity not
be allowed to fall below 35% of the value of the securities in the account. If it does fall below 35%, TradeStation Securities requires the customer to increase the accounts equity to 35% of the value of the securities in the account (if not,
TradeStation Securities will perform closing transactions to bring the customer account above the maintenance requirement). These requirements can be, and often are, raised as TradeStation Securities deems necessary for certain accounts, groups of
accounts, securities or groups of securities. However, there is no assurance that a customer will be willing or able to satisfy a margin call or pay unsecured indebtedness owed to TradeStation Securities.

(7) RECEIVABLES FROM BROKERS, DEALERS, CLEARING ORGANIZATIONS AND CLEARING AGENTS

Amounts receivable from brokers, dealers, clearing organizations and clearing agents consist of the following as of March 31, 2006 and December 31, 2005:



|                                                               |  |               |            |                  |   |

Securities borrowed transactions require TradeStation Securities to provide the counterparty with
collateral in the form of cash and are recorded at the amount of cash collateral advanced to the lender. TradeStation Securities monitors the market value of securities borrowed on a daily basis, and collateral is adjusted as necessary based upon
market prices. See Note 10  COMMITMENTS AND CONTINGENCIES  General Contingencies and Guarantees.

As of March 31,
2006 and December 31, 2005, TradeStation Securities serviced its institutional equities accounts through Bear, Stearns Securities Corp., futures trades were cleared through R.J. OBrien & Associates and forex trades were cleared
through Gain Capital Group, Inc., all on a fully-disclosed basis (Bear, Stearns Securities Corp., R.J. OBrien & Associates, and Gain Capital Group, Inc. are collectively referred to as clearing agents or clearing
agent firms). These clearing agents provide services, handle TradeStation Securities customers funds, hold securities, futures and forex positions, and remit monthly activity statements to the customers on behalf of TradeStation
Securities.

(8) PAYABLES TO BROKERAGE CUSTOMERS

As of March 31, 2006, payables to brokerage customers consist primarily of cash balances in brokerage customer accounts. At March 31, 2006 and December 31, 2005, payables to customers totaled $527.7
million and $523.9 million, respectively. These funds are the principal source of funding for margin lending. At March 31, 2006 and December 31, 2005, TradeStation Securities was paying interest at the rate of 1.125% per annum on cash
balances in excess of $10,000 in equities brokerage customer accounts.

(9) NET CAPITAL REQUIREMENTS

TradeStation Securities is subject to the net capital requirements of the SECs Uniform Net Capital Rule (Rule 15c3-1) and the Commodity
Futures Trading Commissions financial requirement (Regulation 1.17). TradeStation Securities calculates its net capital requirements using the alternative method, which requires the maintenance of minimum net capital, as defined by
the rules, equal to the greater of (i) $250,000 and (ii) 2.0% of aggregate customer debit balances. Customer debit items are a function of customer margin receivables and may fluctuate significantly, resulting in a significant fluctuation
in the Companys net capital requirements. At March 31, 2006, TradeStation Securities had net capital of approximately $40.0 million (38.9% of aggregate debit items), which was approximately $37.9 million in excess of its required net
capital of approximately $2.1 million. At December 31, 2005, TradeStation Securities had net capital of approximately $35.3 million (36.6% of aggregate debit items), which was approximately $33.4 million in excess of its required net capital of
approximately $1.9 million.

(10) COMMITMENTS AND CONTINGENCIES

Restricted Cash

As of March 31,
2006, the Company had $1.7 million of restricted cash supporting a ten-year lease agreement for its corporate headquarters.

Line of
Credit and Guarantee

In June 2005, TradeStation Securities entered into a loan agreement for a revolving credit facility which
TradeStation Group has guaranteed. The revolving credit facility provides for borrowings up to $10 million, expires on its first anniversary (June 16, 2006) if not extended or renewed, and is payable on demand. The credit facility is available for
TradeStation Securities short-term working capital needs. Borrowings under the credit facility bear interest at the LIBOR Market Index Rate plus 1.7% (6.5% as of March 31, 2006) and the outstanding balance must be paid down to a maximum
balance of $1,000 on at least five days each month. Accrued interest is payable monthly. There is an unused line of credit fee equal to 25 basis points per annum on the average daily unused available principal balance for the preceding calendar
quarter, which is waived if the Company and/or any of its subsidiaries maintain, in the aggregate, on average during a quarterly period, over $1 million of deposits with the counter-party during the first year and, if renewed, over $10 million
thereafter. There have not been any borrowings under this line of credit, and the Company has not incurred any unused line of credit fees through March 31, 2006.

Operating Leases

The Company has a ten-year lease expiring in August 2012 (with two 5-year renewal
options) that commenced in the summer of 2002 for an approximately 70,000 square foot corporate headquarters in Plantation, Florida. Rent escalations, free rent, and leasehold and other incentives are recognized on a straight-line basis over
the initial term of this lease.

In addition to its corporate headquarters, the Company has five non-cancelable operating leases for
facilities (including 2 data centers) with expirations ranging from May 2006 to February 2011. In addition to the leases for facilities, the Company leases certain office equipment and furniture. Future minimum lease payments as of
March 31, 2006 under all operating leases are as follows:

##### Table of Contents

During the three months ended March 31, 2006 and 2005, total rent expense (which is included in
occupancy and equipment and data centers and communications in the accompanying consolidated statements of income) was approximately $852,000 and $861,000, respectively.

Purchase Obligations

As of March 31, 2006, the Company had various purchase obligations through
May 2010 of approximately $1.5 million, $642,000, $72,000, $72,000 and $30,000, during 2006, 2007, 2008, 2009 and 2010, respectively, related primarily to back office systems and telecommunications services.

Litigation and Claims

Three lawsuits
were filed in 2003 by former principal owners of onlinetradinginc.com corp. (the predecessor of TradeStation Securities) against the Company, certain of its directors and executive officers and certain family partnerships owned by two of the
executive officers. On July 25, 2003, Benedict S. Gambino, from whom the Company, as of October 18, 2002, purchased 2,417,000 shares of its common stock in a private transaction, filed a lawsuit against the Company and three of its
executive officers, William R. Cruz, Ralph L. Cruz and Marc J. Stone, in the Circuit Court of Broward County, State of Florida. This lawsuits allegations include violation of the Florida Securities and Investor Protection Act, common law
fraud, negligent misrepresentation, breach of fiduciary duty and breach of contract. On August 18, 2003, Andrew A. Allen Family Limited Partnership (owned and controlled by Andrew A. Allen), from whom the Company, as of November 26, 2002,
purchased 1,000,000 shares of its common stock in a private transaction, filed a lawsuit against the same defendants in the same court. This lawsuits allegations include violation of the Florida Securities and Investor Protection Act, common
law fraud, breach of fiduciary duty, negligent misrepresentation and fraudulent inducement. On August 28, 2003, Farshid Tafazzoli and E. Steven zum Tobel filed a lawsuit against the Company, William and Ralph Cruz, family partnerships owned and
controlled by William and Ralph Cruz, Mr. Stone, Charles Wright and David Fleischman in the Circuit Court of Miami-Dade County, State of Florida. Mr. Tafazzolis claims relate to his family partnerships sale, as of May 1,
2002, of 3,000,000 shares of Company common stock to family partnerships owned by William and Ralph Cruz, and Mr. zum Tobels claims relate to his family partnerships sale, as of May 3, 2002, of 133,942 shares of Company common
stock to Charles Wright. This lawsuits allegations include violation of the Florida Securities and Investor Protection Act, common law fraud and breach of fiduciary duty. Each of the three lawsuits seeks rescission of the share purchases
and/or compensatory damages, plus interest, costs and attorneys fees. The Tafazzoli/zum Tobel case is well into the discovery phase of litigation and, in the Allen and Gambino cases, the discovery phase has been substantially completed. In the
Allen case, motions for summary judgment filed by both the plaintiffs and defendants have been denied, and plaintiffs motion to amend their complaint to add a claim for punitive damages was also denied. The Company continues to believe all of
the claims in all three cases are baseless; however, no assurances can be given that a judge or jury will agree with the Companys assessment.

TradeStation Securities is also engaged in routine regulatory matters and civil litigation or other dispute resolution proceedings, including matters which are currently pending relating to NASD OATS reporting and NASD short sales
procedures, and NASD and CFTC arbitrations or proceedings, incidental to, and part of the ordinary course of, its business. The OATS reporting and NASD short sale procedures matters could ultimately result in censures, sanctions, fines and other
negative consequences. There are

##### Table of Contents

currently two NASD arbitrations pending against the Company, one of which seeks several million dollars of actual and
punitive damages. That pending arbitration is set for hearing in early June 2006, and the Company believes the claims made in that case are baseless.

While no assurances can be given, the Company does not believe that the ultimate outcome of any of the above legal matters or claims will result in a material adverse effect on its consolidated financial position,
results of operations or cash flows.

The Company decided, as of June 1, 2002, to no longer carry errors or omissions insurance that
covers third-party claims made by brokerage customers or software subscribers as a result of alleged human or system errors, failures, acts or omissions. This decision was made based upon the Companys assessment of the potential risks and
benefits, including significant increases in premium rates, deductibles and coinsurance amounts, reductions in available per occurrence and aggregate coverage amounts, and the unavailability of policies that sufficiently cover the types of risks
that relate to the Companys business.

Management Continuity Agreements

In December 2005, the Company entered into a management continuity agreement with three of its executive officers. Each management continuity agreement
provides for potential severance payments during the 100-day period following a change in control, as that term is defined in the agreement, in an amount equal to up to two years of the executives annual compensation (in the aggregate for all
three executive officers, currently approximately $2.0 million). The management continuity agreements do not commit the Company to retain any executives services for any fixed period of time, do not provide for severance payments unless the
Company undergoes a change in control, and do not represent new hires or appointments, as each executive has been serving in his current positions for several years.

General Contingencies and Guarantees

In the ordinary course of business, there are various
contingencies which are not reflected in the consolidated financial statements. These include customer activities involving the execution, settlement and financing of various customer securities and futures transactions. These activities may expose
the Company to off-balance sheet credit risk in the event the customers are unable to fulfill their contractual obligations.

In margin
transactions, TradeStation Securities may be obligated for credit extended to its customers by TradeStation Securities or its clearing agents that is collateralized by cash and securities in the customers accounts. In connection with
securities activities, TradeStation Securities also executes customer transactions involving the sale of securities not yet purchased (short sales), all of which are transacted on a margin basis subject to federal, self-regulatory
organization and individual exchange regulations and TradeStation Securities internal policies. Additionally, TradeStation Securities may be obligated for credit extended to its customers by its clearing agents for futures transactions that
are collateralized by cash and futures positions in the customers accounts. In all cases, such transactions may expose TradeStation Securities to significant off-balance sheet credit risk in the event customer collateral is not sufficient to
fully cover losses that customers may incur. In the event customers fail to satisfy their obligations, TradeStation Securities may be required to purchase or sell financial instruments at prevailing market prices to fulfill the customers
obligations.

TradeStation Securities seeks to manage the risks associated with its customers activities by requiring customers to
maintain collateral in their margin accounts in compliance with various regulatory requirements, internal requirements, and the requirements of clearing agents. TradeStation Securities and its clearing agents monitor required margin levels on an
intra-day basis and, pursuant to such guidelines, require the customers to deposit additional collateral or to reduce positions when necessary. For further discussion, see Note 6  RECEIVABLES FROM BROKERAGE CUSTOMERS, NET.

TradeStation Securities borrows securities temporarily from other broker-dealers in connection with its broker-dealer business. TradeStation Securities
deposits cash as collateral for the securities borrowed.

Decreases in securities prices may cause the market value of the securities borrowed to fall below the
amount of cash deposited as collateral. In the event the counterparty to these transactions does not return the cash deposited, TradeStation Securities may be exposed to the risk of selling the securities at prevailing market prices. TradeStation
Securities seeks to manage this risk by requiring credit approvals for counterparties, by monitoring the collateral values on a daily basis, and by requiring additional collateral as needed.

The customers financing and securities settlement activities may require TradeStation Securities and its clearing agents to pledge customer
securities as collateral in support of various secured financing sources, which may include bank loans. In the event the counterparty is unable to meet its contractual obligation to return customer securities pledged as collateral, TradeStation
Securities may be exposed to the risk of needing to acquire the securities at prevailing market prices in order to satisfy its obligations. TradeStation Securities seeks to manage this risk by monitoring the market value of securities pledged on a
daily basis.

TradeStation Securities provides guarantees to its clearing organization and exchanges under their standard membership
agreements, which require members to guarantee the performance of other members. Under the agreements, if another member becomes unable to satisfy its obligations to the clearing organization or exchange, other members would be required to meet
shortfalls. TradeStation Securities liability under these arrangements is not quantifiable and may exceed the cash and securities it has posted as collateral. However, management believes that the possibility of the Company being required to
make payments under these arrangements is remote. Accordingly, no liability has been recorded for these potential events.

(11) INCOME TAXES

During the three months ended March 31, 2006, the Company recorded an income tax provision of $4.5 million based upon its current
estimated annual effective income tax rate of approximately 39%. During the three months ended March 31, 2005, the Company recorded an income tax provision of $2.1 million based upon its then-estimated annual effective income tax rate of
approximately 38%, which was partially offset by adjustments to its deferred income tax assets to reflect its anticipated federal income tax rate and other deferred income tax adjustments.

As of March 31, 2006, for financial reporting purposes, the Company estimates that it had available for federal income tax purposes total net
operating loss carryforwards and income tax credit carryforwards of approximately $2.5 million and $124,000, respectively (expiring between 2010 and 2019). These amounts are subject to annual usage limitations of approximately $545,000. These
limitations are cumulative to the extent they are not utilized in any year.

(12) SEGMENT AND RELATED INFORMATION

For the three months ended March 31, 2006 and 2005, TradeStation Group operated in two principal business segments: (i) brokerage services; and
(ii) software products and services. The Company evaluates the performance of its segments based on revenue and income before income taxes. The brokerage services segment represents the operations of TradeStation Securities and the software
products and services segment represents the operations of TradeStation Technologies. Intercompany transactions between segments are based upon an intercompany licensing and support agreement and an expense-sharing agreement, which reflect current
business relationships and complies with applicable regulatory requirements. All significant intercompany transactions and balances have been eliminated in consolidation.

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This
discussion should be read and evaluated in conjunction with the Consolidated Financial Statements and the Notes to Consolidated Financial Statements of TradeStation Group and its subsidiaries contained herein and with the issues, uncertainties and
risk factors related to our business and industry described in ITEM 1A. RISK FACTORS of PART I of the Annual Report on Form 10-K of TradeStation Group for the year ended December 31, 2005. The results of operations for an interim period
are not necessarily indicative of results for the year, or for any subsequent period.

Overview and Recent Developments

TradeStation Securities is a leading online brokerage firm that serves the active trader and certain institutional trader markets, and is the
companys principal operating subsidiary. TradeStation Securities is a registered broker-dealer and futures commission merchant, and is a member of the NASD, New York Stock Exchange (NYSE), Securities Investor Protection Corporation (SIPC),
National Futures Association (NFA), National Securities Clearing Corporation and the Depository Trust Company (together, the Depository Trust & Clearing Corporation or DTCC), Options Clearing Corporation (OCC), American Stock Exchange
(AMEX), Archipelago Exchange (ARCX), Boston Options Exchange (BOX), Chicago Board Options Exchange (CBOE), Eurex US, International Securities Exchange (ISE), Pacific Exchange (PCX) and Philadelphia Stock Exchange (PHLX). TradeStation
Securities business is also subject to the rules and requirements of the Securities and Exchange Commission (SEC), Commodity Futures Trading Commission (CFTC) and state regulatory authorities (the firm is registered to conduct its brokerage
business in all 50 states and the District of Columbia). TradeStation Securities self-clears most of its equities and equity options business, and uses an established futures clearing firm and an established forex dealer firm to clear its futures
and forex business.

TradeStation Securities revenues consist primarily of transactional commissions and fees (including monthly
platform fees), and interest derived from customer balances and margin lending to customers. With respect to monthly platform fees (a $99.95 charge made to less active brokerage customers for being granted access to use the TradeStationtrading platform), effective September 1, 2005 we launched a strategic marketing initiative which reduced materially the trading activity thresholds that need to be met to qualify for a waiver of the monthly platform fee. Effective
December 1, 2005, we launched two additional strategic marketing initiatives designed mainly to accelerate growth in our futures business. The first of the December 2005 initiatives, designed to attract high-volume futures traders, was the
change from our one-price-fits-all futures commission structure to a tiered commission structure that rewards more active traders with lower pricing. Under the new pricing structure, the commission charged over the applicable exchange fee ranges
from $1.20 down to 25 cents per contract (per side). Also, our old price plan charged an all-in-one futures commission that included both exchange and brokerage fees. Under the new plan, these charges are unbundled, so that the customer pays the
applicable exchange fees for the contracts traded, plus the tiered TradeStation fees applicable to that customer. This enables customers to see how much each exchange charges for trades, and to better understand and take advantage of reduced fees
for exchange members. The second of the December 2005 initiatives was to further reduce the trading activity thresholds that futures, forex and equity options customers need to meet to qualify for a waiver of the monthly platform fee. Assuming no
offsetting benefits, the per month impact of the December 2005 marketing initiatives during the first quarter of 2006 was decreased brokerage commissions and fees of approximately $300,000 and decreased net income of approximately $186,000. We
believe such marketing initiatives will contribute, and may have already contributed during the first quarter of 2006, to our account growth. However, we cannot measure specifically how many accounts are added because of these initiatives and no
assurances can be given that material offsetting benefits will be achieved from any of these initiatives.

Beginning in September 2004,
TradeStation Securities commenced equities self-clearing operations for its active trader client base and commenced omnibus clearing of its standardized equity option trades through Broadcort, a division of Merrill Lynch. Beginning March 29,
2005, following issuance of its

membership in the OCC, TradeStation Securities commenced full self-clearing of its standardized equity options trades for
its active trader client base. Self-clearing has provided substantial cost savings and efficiencies. TradeStation Securities currently clears institutional account securities trades through Bear, Stearns Securities Corp. on a fully-disclosed basis.
Futures trades are cleared through R.J. OBrien & Associates, and forex trades, through July 15, 2005, were cleared through R.J. OBrien Foreign Exchange, each on a fully-disclosed basis. Subsequent to July 15, 2005,
forex trades have been cleared through Gain Capital Group, Inc. on a fully-disclosed basis (Bear, Stearns Securities Corp., Broadcort, R.J. OBrien & Associates, R.J. OBrien Foreign Exchange, and Gain Capital Group, Inc. are
collectively referred to as clearing agents or clearing agent firms). In connection with an extension of its futures clearing agreement (which was set to expire December 31, 2005) and the agreement with its new forex
clearing agent, TradeStation Securities began receiving in July 2005 materially more favorable interest-sharing and clearing fee/deal-spread sharing arrangements. These benefits are not based on growth in trading volume or any other contingency.

As of March 31, 2006, TradeStation Securities had 26,797 equities, futures and forex accounts (the vast majority of which were
equities and futures accounts). Effective January 1, 2006, a brokerage account is defined as an account that either has a positive asset balance of at least $200 or has activity within the past 180 days. In other words, an account is deemed
inactive and is not included in counting total brokerage accounts if it has less than a $200 balance and has had no activity within the past 180 days. The effect of this modified account definition was a net positive adjustment of 511 accounts as of
January 1, 2006 (i.e., a positive adjustment to the number of futures and forex accounts exceeded a negative adjustment to the number of equities accounts by 511). Prior periods have not been and will not be restated to reflect the modification
to the definition. The March 31, 2006 number of accounts represented a net increase of 2,313 accounts (excluding the 511 account net positive adjustment) during the first quarter of 2006. TradeStation brokerage clients generated the following
client account metrics in the 2006 first quarter:



|                                      |  |   |       
|------------------------------------- |  | - | ------
|Annualized trades                     |  |   | 582   
|Annualized net revenue per account    |  | $ | 4,300 
|Average assets per account  equities |  | $ | 90,000
|Average assets per account  futures  |  | $ | 17,500

During the three months ended March 31, 2006, TradeStation Securities brokerage
customer account base averaged 59,057 daily average revenue trades (often called DARTs), an increase of 48% when compared to 39,801 during the three months ended March 31, 2005.

We compute DARTs as follows: For equities and equity options, a revenue trade included to calculate DARTs is a commissionable trade order placed by the
customer and executed, regardless of the number of shares or contracts included in the trade order. For futures and forex, a revenue trade included to calculate DARTs is one round-turn commissionable futures contract traded, or one round-turn lot
(or forex deal) traded, regardless of the number of individual orders made and executed (i.e., one futures or forex order may contain numerous contracts or deals, but each round-turn contract and deal is counted as a separate revenue trade). When
viewing our DARTs, it should be taken into account that, for equities and equity options, we charge commissions based on share volume and number of contracts traded (and not by revenue trade used to calculate DARTs). For futures, we charge
commissions on a per contract basis (so each futures revenue trade included to calculate DARTs represents a round-turn commissionable contract traded). It should be noted that as we continue to acquire futures customers who trade larger volumes, and
seek to accelerate our acquisition of higher-volume futures accounts, such as futures traders who may be attracted by our new tiered commission pricing structure and institutional traders, the number of futures revenue trades included in DARTs on a
per order basis will likely grow. Also, it should be noted that all DARTs are not equal. The revenue we derive from each revenue trade depends on the asset in question (equities, equity options, futures, forex  each has a different per unit
revenue structure), and, within each asset class, revenue per equity, contract or deal varies to the extent higher volume traders receive more favorable pricing, which they often do.

TradeStation Technologies, the companys other operating subsidiary, owns all of our intellectual
property. TradeStation Technologies also provides subscription services for TradeStation. The subscription version of TradeStationis an institutional-quality service that offers strategy trading software tools that generate real-time
buy and sell alerts based upon the subscribers programmed strategies, but does not include order execution. Subscribers are charged a monthly subscription fee.

We also have a United Kingdom subsidiary, TradeStation Europe Limited, which is currently in its start-up phase. In February 2006, TradeStation Europe became authorized by the United Kingdoms Financial Services
Authority (FSA) to act as a Securities and Futures Firm in the United Kingdom to introduce accounts to TradeStation Securities. The FSA category of authorization is ISD Category D Arranger, meaning that TradeStation Europe
may now solicit and introduce UK clients who are active, experienced traders to its US affiliate for equities, options, futures and forex account services. TradeStation Europe is now in the process of putting together what are known as
European Passport filings for various countries in the European Union, pursuant to which the company may use its FSA authorization to qualify to conduct similar business throughout the European Union. We do not anticipate revenues from
TradeStation Europes operations until, at the earliest, late 2006.

Critical Accounting Policies and Estimates

Our significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K of
TradeStation Group for the year ended December 31, 2005  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and
expenses during the reporting period. Actual results could differ materially from those estimates.

Brokerage Commissions and Fees and
Net Interest Income.Brokerage commissions and fees and net interest income are the key components of our results of operations and are comprised mainly of: (i) brokerage commissions and fees earned from securities, futures and forex
transactions and, to a lesser extent, monthly platform fees earned from brokerage customers using the TradeStationonline trading platform; and (ii) net interest earned and paid from self-clearing operations (primarily interest earned on
brokerage customer cash balances and interest earned from brokerage customer margin debit balances), interest revenue sharing arrangements with clearing agent firms, and interest on corporate cash and cash equivalents. Brokerage commission income
and related clearing costs are recorded on a trade date basis as transactions occur. Platform fees are recorded on an accrual basis as monthly services are provided. Interest revenue and interest expense are recorded on an accrual basis as interest
is earned or incurred.

Income Taxes. In accordance with Statement of Financial Accounting Standards (SFAS)
No. 109, Accounting for Income Taxes,deferred income tax assets should be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Management
evaluates and determines on a periodic basis the amount of the valuation allowance required and adjusts the valuation allowance as needed. As of March 31, 2006 and December 31, 2005, we had no valuation allowance on our deferred income tax
assets. On a periodic basis, we will continue to evaluate our deferred income tax assets to determine if a valuation allowance is required.

Allowance for Potential Credit Losses. We perform periodic credit evaluations and provide allowances based upon our assessment of specifically identified unsecured receivables and other factors, including the customers
likelihood to pay and payment history. As of December 31, 2005, we had an allowance for a potential credit loss of $226,000. There was no allowance as of March 31, 2006 since we collected $200,000 and wrote-off the balance of this
receivable (mostly accrued interest) against this reserve. See Note 6 of Notes to Consolidated Financial Statements  RECEIVABLES FROM BROKERAGE CUSTOMERS, NET, and Note 10  COMMITMENTS AND CONTINGENCIES  General Contingencies
and Guarantees. See Three Months Ended March 31, 2006 and 2005  Expenses  Other.

Uninsured Loss Reserves. We decided, as of June 1, 2002, to no longer carry errors or
omissions insurance that covers third-party claims made by brokerage customers or software subscribers as a result of alleged human or system errors, failures, acts or omissions. This decision was made based upon our assessment of the potential
risks and benefits, including significant increases in premium rates, deductibles and coinsurance amounts, reductions in available per occurrence and aggregate coverage amounts, and the unavailability of policies that sufficiently cover the types of
risks that relate to our business. Each quarter, we continue to evaluate our accruals, if any, for settlements related to claims and potential claims. Estimates of settlements for such potential claims, including related legal fees, are accrued in
the consolidated financial statements, as necessary. The ultimate outcome of such potential claims may be substantially different than our estimates. We have not created any uninsured loss reserves for any of the lawsuits or arbitrations described
in Note 10  COMMITMENTS AND CONTINGENCIES  Litigation and Claims, or to which the company is otherwise subject.

Results of
Operations

For the three months ended March 31, 2006 and 2005, we operated in two principal business segments: (i) brokerage
services; and (ii) software products and services. The brokerage services segment represents the operations of TradeStation Securities and the software products and services segment represents the operations of TradeStation Technologies. We
ceased marketing our legacy software products and subscription software services in 2000. Our primary sources of consolidated revenue are currently generated from the brokerage services segment, and the brokerage services segment should continue to
produce the majority of our revenues for the foreseeable future. For the three months ended March 31, 2006 and 2005, the brokerage services segment accounted for approximately 91% and 89%, respectively, of our total consolidated net revenues.
Given the size of those percentages, other than our discussion and table in Note 12  SEGMENT AND RELATED INFORMATION, we will discuss our results of operations for the overall company instead of on a segmented basis. The following table
presents, for the periods indicated, our consolidated statements of income data and presentation of that data as a percentage of change from period to period:

##### Table of Contents

Three Months Ended March 31, 2006 and 2005

Net revenues were $29.4 million for the three months ended March 31, 2006, as compared to $21.8 million for the three months ended March 31,
2005, an increase of $7.5 million, or 35%. The primary reasons were increased net interest income of $4.9 million, or 137%, as a result of higher interest rates, higher aggregate cash and margin balances and a more favorable interest-sharing
arrangement with our futures clearing firm, and increased brokerage commissions and fees of approximately $2.8 million, or 18%, as a result of higher trade volume related mostly to growing our brokerage account base.

Income before income taxes was $11.5 million (39% of net revenues) for the three months ended March 31, 2006, as compared to $5.9 million (27% of
net revenues) for the three months ended March 31, 2005, an increase of $5.6 million, or 95%. Our improvement in income before income taxes was due primarily to our increased net interest income of $4.9 million and our increased brokerage
commissions and fees of $2.8 million, partially offset by increased employee compensation and benefits of $1.4 million and increased clearing and execution costs of $997,000. The increase in our income before income tax margin from 27% to 39% was
due primarily to our increased net interest income.

During the three months ended March 31, 2006, we recorded an income tax provision
of $4.5 million based upon our current estimated annual effective income tax rate of approximately 39%. During the three months ended March 31, 2005, we recorded an income tax provision of $2.1 million based upon our then-estimated annual
effective income tax rate of approximately 38%, which was partially offset by adjustments to our deferred income tax assets to reflect our current anticipated federal income tax rate and other deferred income tax adjustments. See Income
Taxes below.

Net income was approximately $7.0 million for the three months ended March 31, 2006, as compared to $3.8 million
for the three months ended March 31, 2005, an increase of $3.2 million, or 84%, due primarily to our 35% year-over-year increase in revenues and the increase of our income before income tax margin from 27% to 39%, partially offset by a higher
effective tax rate in the 2006 first quarter.

Revenues

Brokerage Commissions and Fees  Brokerage commissions and fees are comprised mainly of commissions for securities, futures and forex transactions and, to a lesser extent, monthly platform and other fees
earned from brokerage customers using the TradeStationonline trading platform. For the three months ended March 31, 2006, brokerage commissions and fees were approximately $18.6 million, as compared to $15.8 million for the three months
ended March 31, 2005. This $2.8 million, or 18%, increase was due primarily to increased brokerage commissions of $3.5 million from higher trading volume related mostly to growing our brokerage customer account base, partially offset by reduced
futures commission pricing, and partially offset by a decrease in platform and other fees as a result of reduced trading activity thresholds that needed to be met to qualify for a waiver of our monthly platform fee, as further discussed in this
paragraph. The industry has been experiencing price pressure and some of our competitors continue to reduce their online brokerage commissions and fees. We continuously review and assess our pricing  both commissions and platform fees. With
respect to monthly platform fees (a $99.95 charge made to less active brokerage customers for being granted access to use the TradeStationtrading platform), effective September 1, 2005 we launched a strategic marketing initiative which
reduced materially the trading activity thresholds that need to be met to qualify for a waiver of the monthly platform fee. Effective December 1, 2005, we launched two other strategic marketing initiatives designed mainly to accelerate growth
in our futures business. The first of the December 2005 initiatives, designed to attract high-volume futures traders, was the change from our one-price-fits-all futures commission structure to a tiered commission structure that rewards more active
traders with lower pricing. Under the new pricing structure, the commission charged over the applicable exchange fee ranges from $1.20 down to 25 cents per contract (per side). Also, our old price plan charged an all-in-one futures commission that
included both exchange and brokerage fees. Under the new plan, these charges are unbundled, so that the customer pays the applicable exchange fees for the contracts traded, plus the tiered TradeStation fees applicable to that customer. This enables
customers to see how much each exchange charges for trades, and to better understand and take advantage of reduced fees for exchange members. The second of the December 2005 initiatives was to further reduce the trading activity

thresholds futures, forex and equity options customers need to meet to qualify for a waiver of the monthly platform fee.
Assuming no offsetting benefits, the per month impact of the December 2005 marketing initiatives during the first quarter of 2006 was decreased brokerage commissions and fees of approximately $300,000 and decreased net income of approximately
$186,000. We believe such marketing initiatives will contribute, and may have already contributed during the first quarter of 2006, to our account growth. However, we cannot measure specifically how many accounts have been added because of these
initiatives and no assurances can be given that material offsetting benefits will be achieved from any of these initiatives.

Interest
Income Interest income is comprised of interest earned from self-clearing operations (primarily interest earned on brokerage customer cash balances and interest earned from brokerage customer margin debit balances), interest
revenue-sharing arrangements with clearing agent firms, and interest on corporate cash and cash equivalents. For the three months ended March 31, 2006, interest income was $9.5 million, as compared to approximately $4.2 million for the three
months ended March 31, 2005. This $5.4 million, or 129%, increase was due primarily to increased interest rates (increases in the federal funds target rate of interest, more favorable interest income-sharing with our futures clearing agent and
increased base margin debit interest rates) and account growth. Since the beginning of 2005, the federal funds target rate of interest was increased by 25 basis points ten times, from 2.25% to 4.75% at March 31, 2006. These increases resulted
in increases in the amounts we earned on our clients cash account balances. During the three months ended March 31, 2006, the weighted average federal funds target rate of interest was approximately 4.43%, an increase of 82% as compared
with the weighted average rate of 2.44% for the same period in 2005. Also, since February 2005 we increased the base margin debit interest rate that we charge our customers from 6.375% in January 2005 to 8.125% by August 2005, and such rate has
remained constant through March 31, 2006. During the three months ended March 31, 2006, the weighted average base margin debit rate that we charge our customers was 24% higher than the rate charged to our customers during the same period
of 2005. Interest income for future periods may be materially affected by further increases, no actions or decreases regarding the federal funds target rate and the extent, if any, by which our customer cash account balances increase or
decrease, as well as any decisions we may make to provide more favorable debit or credit rates to our customers.

Brokerage Interest
Expense Brokerage interest expense consists of amounts paid or payable to brokerage customers based on credit balances maintained in brokerage accounts and other brokerage-related interest expense. Brokerage interest expense does not
include interest on company borrowings, if any, which is included in Expenses  Other Expenses below. For the three months ended March 31, 2006, brokerage interest expense was $1.1 million, as compared to $614,000 for the three
months ended March 31, 2005. This $485,000, or 79%, increase was due primarily to increased interest rates and account growth. During the three months ended March 31, 2006, the average annual credit interest rate paid to our equities
customers was 1.125%, as compared to approximately 0.764% during the three months ended March 31, 2005. As of March 31, 2006 and through the date of this report, our equities customers earn interest at the rate of 1.125% per annum on
the portion, if any, of their cash balances in excess of $10,000, and futures and forex customers earn no interest on their cash balances. Factors that will affect brokerage interest expense in the future include: the growth, and mix of growth, of
our brokerage customer base in equities, futures and forex; average assets per account and the portion of account assets held in cash; and future decisions concerning credit or debit interest rates offered to our equities, futures and forex
customers.

Subscription Fees and Other Subscription fees and other revenues are comprised primarily of monthly fees earned
for providing streaming real-time, Internet-based trading analysis software tools and data services to non-brokerage customers and, to a lesser extent, royalties and commissions received from third parties whose customers use our legacy software
products and direct sales of our legacy customer software products. Subscription fees and other revenues were approximately $2.3 million during the three months ended March 31, 2006, as compared to $2.5 million during the three months ended
March 31, 2005, a decrease of approximately $114,000, or 5%, due primarily to a decrease in royalties and commissions received from third parties and, to a lesser extent, decreased subscription fees. The expected



23

##### Table of Contents

decrease in royalties and subscription fees is the result of not having marketed subscription services or legacy customer
software products since 2000. Effective May 1, 2006, we increased the rates we charge for most of our monthly subscriptions to non-brokerage customers by $50. The positive impact, if any, of this increase will depend upon how many customers
terminate their subscription service or do not buy new subscriptions as a result of the price increase, and how many (if any) decide to become brokerage customers instead of continuing their subscriptions. We expect royalties and commissions from
third parties to continue to decrease and to reach a de minimus amount by year end.

Expenses

Employee Compensation and Benefits Employee compensation and benefits expenses are comprised primarily of employee salaries, sales
commissions and bonuses (and, beginning in 2006, stock-based compensation) and, to a lesser extent, payroll taxes, employee benefits (including group health insurance and employer contributions to benefit programs), recruitment, temporary employee
services and other related employee costs. Employee compensation and benefits expenses were $7.0 million for the three months ended March 31, 2006, as compared to $5.6 million for the three months ended March 31, 2005, an increase of $1.4
million, or 25%. This increase was due primarily to increases in wages paid to employees of $480,000 and stock-based compensation of $400,000 and, to a lesser extent, increases in accrued bonuses, sales commissions, employee benefits and recruitment
and related expenses. The increase in wages was due to annual merit increases and increased headcount. During the three months ended March 31, 2006, there was an average of 270 full-time equivalent employees, as compared to 257 full-time
equivalent employees during the three months ended March 31, 2005. Employee compensation and benefits expenses are anticipated to increase during 2006 as a result of planned additions to employee headcount to support expansion of our business
operations, including the July 2006 planned opening of a sales office in Chicago. For further discussion of stock-based compensation expense, see Recently Issued Accounting Standardsbelow.

Clearing and Execution  Clearing and execution expenses include the costs associated with executing and clearing customer trades, including
fees paid to clearing agents and clearing organizations, exchanges and other market centers, fees and royalties paid for the licensing of self-clearing, back-office software systems and related services, and commissions paid to third-party
broker-dealers. Clearing and execution expenses were approximately $5.8 million for the three months ended March 31, 2006, as compared to $4.8 million for the three months ended March 31, 2005, an increase of approximately $997,000, or
21%, as a result of higher trade volume. Clearing and execution costs as a percentage of brokerage commissions and fees increased slightly to 31% during the three months ended March 31, 2006, as compared to 30% during the three months ended
March 31, 2005. This increase in clearing and execution expenses, as a percentage of brokerage commissions and fees, was due primarily to lower platform fees as a result of reduced trading activity thresholds that needed to be met to qualify
for a waiver of the monthly platform fee and a new futures brokerage commission structure that rewards more active traders with lower pricing, partially offset by the benefits received from self-clearing of equity option trades in the 2006 first
quarter and the continued benefits of equities self-clearing as equities brokerage commissions increased year over year (a substantial portion of which are fixed) and reduced clearing fee rates for futures.

Data Centers and Communications  Data centers and communications expenses are comprised of: (i) data communications costs necessary to
connect our server farms directly to electronic marketplaces, data sources and to each other; (ii) data communications costs and rack space at our facilities where the data server farms are located; (iii) data distribution and exchange
fees; and (iv) telephone, internet and other communications costs. Data centers and communications expenses were $1.5 million for the three months ended March 31, 2006, as compared to $1.6 million for the three months ended March 31,
2005, a decrease of $43,000, or 3%.

Advertising  Advertising expenses are comprised of marketing programs, primarily:
advertising in various media, including direct mail, television and print media; account opening kits, including postage; brochures; and other promotional items, including exhibit costs for industry events. Advertising expenses



24

##### Table of Contents

for the three months ended March 31, 2006 were $957,000, as compared to $962,000 for the three months ended
March 31, 2005, a decrease of $5,000, or 1%. The quality and success of, and potential continuous changes in, sales or marketing strategies (which continue to evolve), including the effects of our recent decisions to lower futures commissions
and the trade activity thresholds that need to be met for a brokerage customers monthly platform fee to be waived, are factors that may impact the level of advertising in the future.

Professional Services  Professional services expenses are comprised of fees for legal, accounting, tax, and other professional and
consulting services. Professional services expenses were approximately $758,000 for the three months ended March 31, 2006, as compared to $1.1 million for the three months ended March 31, 2005, a decrease of $294,000, or 28%, due primarily
to decreased legal fees.

Occupancy and Equipment Occupancy and equipment expenses include rent, utilities, property taxes,
repairs, maintenance and other expenses pertaining to our office space. Occupancy and equipment expenses were $622,000 for the three months ended March 31, 2006, as compared to $601,000 for the three months ended March 31, 2005, an
increase of $21,000, or 3%.

Depreciation and Amortization  Depreciation and amortization expenses consist primarily of
depreciation on property and equipment and, to a lesser extent, amortization of intangible assets (in 2005 only). Depreciation and amortization expenses were $483,000 for the three months ended March 31, 2006, as compared to $434,000 for the
three months ended March 31, 2005, an increase of $49,000, or 11%. This increase was due primarily to higher depreciation of fixed assets related to capital expenditures.

Other  Other expenses include insurance, regulatory fees and related costs, employee travel and entertainment, settlements for legal
matters, costs related to training workshops, software maintenance, public company expenses, supplies, postage, exchange memberships, customer debits and errors, bank charges and other administrative expenses. Other expenses were $780,000 for the
three months ended March 31, 2006, as compared to $911,000 for the three months ended March 31, 2005, a decrease of $131,000, or 14%. This decrease was due primarily to decreased customer debits and errors of $186,000 and decreased
insurance of $82,000, partially offset by increases in regulatory fees and expenses, settlements, public company expenses, supplies and travel-related expenses. The decrease in customer debits and errors was due primarily to the collection of
$200,000 of a receivable from a brokerage customer, previously considered uncollectible and fully reserved.

Variability of Quarterly Results

The operating results for any quarter are not necessarily indicative of results for any future period or for the full year. Our
quarterly revenues and operating results have varied in the past, and are likely to vary in the future. Such fluctuations may result in volatility in the price of our common stock. For information regarding the risks related to the variability of
quarterly results, see ITEM 1A. RISK FACTORS of PART I of the Annual Report on Form 10-K of TradeStation Group for the year ended December 31, 2005.

Income Taxes

During the three months ended March 31, 2006, we recorded an income tax provision of $4.5 million based
upon our estimated annual effective income tax rate of approximately 39%. During the three months ended March 31, 2005, we recorded an income tax provision of $2.1 million based upon our then-estimated annual effective income tax rate of
approximately 38%, which was partially offset by adjustments to our deferred income tax assets to reflect our then-anticipated federal income tax rate of 35% and other deferred income tax adjustments.

As of March 31, 2006, for financial reporting purposes, we estimate that we had available for federal income tax purposes total net operating loss
carryforwards and income tax credit carryforwards of approximately $2.5 million and $124,000, respectively (expiring between 2010 and 2019). These amounts are subject to annual usage limitations of approximately $545,000. These limitations are
cumulative to the extent they are not utilized in any year.

Liquidity and Capital Resources

As of March 31,
2006, we had cash and cash equivalents of approximately $60.8 million, of which $1.7 million was restricted, supporting a facility lease. On April 4, 2006, as a result of TradeStation Securities March 31, 2006 month-end calculation
under Rule 15c3-3 of the Securities Exchange Act of 1934 (see below), $18.4 million of the $452.1 million of cash segregated in compliance with federal regulations shown on our consolidated balance sheet at March 31, 2006 was transferred
to cash and cash equivalents.

As of March 31, 2006, TradeStation Securities had: $452.1 million of cash segregated in compliance with
federal regulations in special reserve bank accounts for the exclusive benefit of customers under Rule 15c3-3 of the Securities Exchange Act of 1934 and other regulations; receivables from brokerage customers of $70.1 million; and receivables
from brokers, dealers, clearing organizations and clearing agents of $28.3 million. Client margin loans are demand loan obligations secured in part by cash and/or readily marketable securities. Receivables from and payables to brokers, dealers,
clearing organizations and clearing agents represent primarily current open transactions, which usually settle, or can be closed out, within a few business days.

Liquidity needs relating to client trading and margin borrowing activities are met primarily through cash balances in brokerage client accounts, which were $527.7 million at March 31, 2006. Management believes
that brokerage cash balances and operating earnings will continue to be the primary source of liquidity for TradeStation Securities in the future. Additionally, TradeStation Securities has available to it a revolving credit facility (which expires
June 10, 2006, if not extended or renewed) which provides for borrowings up to $10 million for short-term working capital needs and which needs to be fully pre-paid at least five times per calendar month. To date, there have been no borrowings
under this revolving credit facility. See Note 10 of Notes to Consolidated Financial Statements  COMMITMENTS AND CONTINGENCIES  Line of Credit and Guarantee.

TradeStation Securities is subject to the net capital requirements of the SECs Uniform Net Capital Rule (Rule 15c3-1) and the CFTCs financial
requirement (Regulation 1.17). TradeStation Securities calculates net capital requirements using the alternative method, which requires the maintenance of minimum net capital, as defined by the rules, equal to the greater of
(i) $250,000 and (ii) 2.0% of aggregate customer debit balances. Customer debit items are a function of customer margin receivables and may fluctuate significantly, resulting in a significant fluctuation in our net capital requirements. At
March 31, 2006, TradeStation Securities had net capital of approximately $40.0 million (38.9% of aggregate debit items), which was approximately $37.9 million in excess of its required net capital of approximately $2.1 million.

In addition to net capital requirements, as a self-clearing broker-dealer TradeStation Securities is subject to DTCC, OCC, and other cash deposit
requirements, which are and may continue to be large in relation to TradeStation Groups total liquid assets, and which may fluctuate significantly from time to time based upon the nature and size of TradeStation Securities active trader
clients securities trading activity. As of March 31, 2006, we had interest-bearing security deposits and short-term treasury bills totaling $11.2 million with clearing organizations for the self-clearing of equities and standardized
equity option trades.

As of March 31, 2006, we have no long-term debt obligations or capital lease obligations. A summary of our
operating lease obligations (net of subleases) and minimum purchase obligations (related to back-office systems, telecommunications services and advertising) is as follows:

##### Table of Contents

In addition to the purchase obligations set forth in the table above, we currently anticipate, in order
to provide for additional growth of our brokerage business (there being no assurance additional growth will occur), capital expenditures of between $2.5 million and $7.0 million for the remainder of 2006. These capital expenditures are primarily for
the purchase of computer hardware and software for our data server farms, hardware and software to upgrade our telephone and recording systems, the opening of our Chicago office and back-office systems  all to support the growth of our
business and improve and enhance the stability and robustness of our systems. These expenditures are expected to be funded through operating cash flows, capital leases, or a combination of the two.

We anticipate that our available cash resources and cash flows from operations will be sufficient to meet our presently anticipated working capital and
capital expenditure requirements through at least the next twelve months.

Net cash used in operating activities totaled approximately
$15.7 million during the three months ended March 31, 2006, as compared to net cash provided by operating activities of $23.7 million during the three months ended March 31, 2005. Net cash used in operating activities during the three
months ended March 31, 2006 of $15.7 million was due primarily to timing differences related to funding cash segregated in compliance with federal regulations ($18.4 million transferred from cash segregated in compliance with federal
regulations to cash on April 4, 2006, as opposed to $9.5 million transferred from cash to cash segregated in compliance with federal regulations on January 4, 2006) and an increase in receivables from brokerage customers offset by net
income as adjusted for non-cash items, a decrease in receivables from brokers, dealers, clearing organizations and clearing agents, and increases in payables to brokerage customers and accrued expenses. Net cash provided by operating activities
during the three months ended March 31, 2005 of $23.7 million was due primarily to timing differences related to brokerage customer credit balances (including approximately $16.2 million transferred to cash segregated in compliance with federal
regulations on April 4, 2005) and, to a lesser extent, net income of $3.8 million, adjustments for non-cash items of $2.6 million, and a decrease in security deposits with clearing organizations and clearing agents of $2.2 million.

Investing activities used cash of $1.0 million and $1.2 million during the three months ended March 31, 2006 and 2005, respectively. Investing
activities in both years were primarily for capital expenditures (mostly computer hardware to support the growth of our data server farms).

Financing activities provided cash of $2.5 million and $132,000 during the three months ended March 31, 2006 and 2005, respectively. Proceeds from the issuance of common stock related to the exercise of stock options from our incentive
stock plans provided cash of approximately $1.2 million and $136,000 during the three months ended March 31, 2006 and 2005, respectively. Excess tax benefits from the exercise of stock options were approximately $1.2 million during the three
months ended March 31, 2006.

Recently Issued Accounting Standards

We adopted SFAS No. 123 (revised 2004), Share-Based Payment(SFAS No. 123R), effective January 1, 2006. SFAS 123R, which
is a revision of SFAS No. 123, Accounting for Stock-Based Compensation, supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, Statement of Cash Flows. SFAS No. 123R
requires all share-based payments to employees, including grants of employee stock options, to be recognized in the statement of income based on their fair values. Pro forma disclosure is no longer an alternative. We have adopted the fair value



27



---

##### Table of Contents

provisions of SFAS No. 123R using the modified-prospective-transition method. Under the
modified-prospective-transition method of adoption, compensation cost is recognized for all stock-based awards issued after the effective date, and for the portion of outstanding awards for which the requisite service has not yet been rendered
(i.e., stock-based awards granted prior to the effective date, but not yet vested as of the effective date). Under this method of transition, results for prior periods are not restated. During the three months ended March 31, 2006, the adoption
of SFAS 123R resulted in $400,000 of stock-based compensation included in employee compensation and benefits in our consolidated statement of income. Accordingly, our income before income taxes and net income for the three months ended
March 31, 2006 were $400,000 and $379,000, respectively, lower than they would have been if we had continued to account for share-based compensation under APB Opinion No. 25. If we had not adopted SFAS 123R, basic and diluted earnings per
share for the three months ended March 31, 2006 would have been $0.17 and $0.16, respectively, as compared to the reported basic and diluted earnings per share of $0.16 and $0.15, respectively.

Prior to the adoption of SFAS 123R, we presented all benefits of tax deductions resulting from the exercise of stock options as operating cash flows in
the statement of cash flows. SFAS No. 123R requires the benefits of tax deductions in excess of recognized compensation costs to be reported as a financing cash flow, rather than as an operating cash flow as required under the previous
literature. This requirement reduced net operating cash flows and increased net financing cash flows by approximately $1.2 million during the three months ended March 31, 2006. See Note 2  STOCK-BASED COMPENSATION for further information
regarding our stock-based compensation assumptions and expenses, including pro forma disclosures for prior periods as if we had recorded stock-based compensation expenses.

As of March 31, 2006, there was approximately $6.0 million of unrecognized compensation cost, adjusted for estimated forfeitures, related to
unvested stock-based payments granted to the companys employees and non-employee directors. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures, and is expected to be recognized over 3.7 years.

We adopted SFAS No. 154, Accounting Changes and Error Corrections, effective January 1, 2006. SFAS No. 154, which is
a replacement of APB Opinion No. 20, Accounting Changes and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements, provides guidance on accounting for and reporting of accounting changes and error
corrections. It requires a voluntary change in accounting principle to be applied retrospectively to all prior periods financial statements as if the principle had always been applied. Previously, voluntary changes in accounting
principles were required to be recognized by including the cumulative effect of changing to the new accounting principle in net income during the period of change. The adoption of SFAS No. 154 did not have any impact on our consolidated
financial position, results of operations or cash flows.

Off-Balance Sheet Arrangements

In the ordinary course of business, there are various contingencies which are not reflected in the consolidated financial statements. These include
customer activities involving the execution, settlement and financing of various customer securities and futures transactions. These activities may expose the company to off-balance sheet credit risk in the event the customers are unable to fulfill
their contractual obligations.

Nearly all TradeStation Securities customer accounts are margin accounts. In margin transactions,
TradeStation Securities may be obligated for credit extended to its customers by its clearing agents that are collateralized by cash and securities in the customers accounts with those clearing agents. In connection with securities activities,
TradeStation Securities also executes customer transactions involving the sale of securities not yet purchased (short sales), all of which are transacted on a margin basis subject to federal, self-regulatory organization and individual
exchange regulations and TradeStation Securities and its clearing agents internal policies. Additionally, TradeStation Securities may be obligated for credit extended to its customers by its clearing agents for futures transactions that
are collateralized by cash and futures positions in the customers accounts with those clearing agents. In



28



---

##### Table of Contents

all cases, such transactions may expose TradeStation Securities to significant off-balance sheet credit risk in the event
customer collateral is not sufficient to fully cover losses that customers may incur. In the event customers fail to satisfy their obligations, TradeStation Securities may be required to purchase or sell financial instruments at prevailing market
prices to fulfill the customers obligations.

TradeStation Securities seeks to manage the risks associated with its customers
activities by requiring customers to maintain collateral in their margin accounts in compliance with various regulatory requirements, internal requirements, and the requirements of clearing agents. TradeStation Securities and its clearing agents
monitor required margin levels on an intra-day basis and, pursuant to such guidelines, require the customers to timely deposit additional collateral or to reduce positions when necessary.

TradeStation Securities provides guarantees to its clearing organization and exchanges under their standard membership agreements, which require members
to guarantee the performance of other members. Under the agreements, if another member becomes unable to satisfy its obligations to the clearing organization and exchanges, other members would be required to meet shortfalls. TradeStation
Securities liability under these arrangements is not quantifiable and may exceed the cash and securities it has posted as collateral. However, management believes that the possibility of the company being required to make payments under these
arrangements is remote. Accordingly, no liability has been recorded for these potential events.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk generally represents the
risk of loss that may result from the potential change in the value of a financial instrument as a result of fluctuations in interest rates or market prices. We have established policies, procedures and internal processes governing our management of
market risks in the normal course of our business operations. We do not hold any market risk sensitive instruments for trading purposes.

TradeStation Securities seeks to manage the risks associated with our customers activities by requiring customers to maintain margin collateral and reduce concentrated positions in compliance with regulatory and internal guidelines.
TradeStation Securities monitors required margin levels on an intra-day basis and, pursuant to such guidelines, requires customers to deposit additional collateral, or to reduce positions, when necessary.

As a self-clearing broker-dealer, TradeStation Securities holds interest-earning assets, mainly customer funds required to be segregated in compliance
with federal regulations. These funds totaled $452.1 million at March 31, 2006. Interest-earning assets are financed primarily by short-term interest-bearing liabilities, which totaled $527.7 million at March 31, 2006, in the form of
customer cash balances. In addition to earning interest on the customer funds segregated in compliance with federal regulations, TradeStation Securities earns a net interest spread on the difference between amounts earned on customer margin loans
and amounts paid on customer cash balances. Since TradeStation Securities establishes the rate paid on customer cash balances and the rate charged on customer margin loans, a substantial portion of our interest rate risk is under our direct
management. TradeStation Securities also earns interest from interest revenue-sharing arrangements with its clearing agents. We estimate that, based upon our brokerage customer balances at March 31, 2006, for each basis point increase or
decrease in interest rates retained by the company there is an annual impact of approximately $44,000 to our net income.

Changes in
interest rates also affect the interest earned on our cash and cash equivalents and security deposits. To reduce this interest rate risk, we are currently invested in investments with short maturities. As of March 31, 2006, our cash and cash
equivalents consisted primarily of interest-bearing cash deposits and money market funds and our security deposits consisted primarily of interest-bearing cash deposits and treasury bills. Any increase or decrease in interest rates will not have a
material impact on our interest earned on our corporate cash balances or security deposits.

TradeStation Securities seeks to manage risks
associated with its securities borrowing activities by requiring credit approvals for counterparties, by monitoring the collateral values for securities borrowed on a daily basis and by obtaining additional collateral as needed. See Note 10 of Notes
to Consolidated Financial Statements  COMMITMENTS AND CONTINGENCIES  General Contingencies and Guarantees.

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation of the
effectiveness of the design and operation of the companys disclosure controls and procedures was made under the supervision and with the participation of the companys management, including the Co-Chief Executive Officers and the Chief
Financial Officer. Based on that evaluation, the companys management, including the Co-Chief Executive Officers and the Chief Financial Officer, concluded that the companys disclosure controls and procedures were effective at the
reasonable assurance level as of the end of the period covered by this report. A system of controls, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the system of controls are met, and no evaluation
of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

There have been no changes in the companys internal control over financial reporting that occurred during the first quarter of 2006 that have materially affected, or are reasonably likely to materially affect, the companys
internal control over financial reporting.

ITEM 1A. RISK FACTORS

There have been no material changes in risk factors during the first quarter of
2006 from those previously discussed in ITEM 1A. RISK FACTORS of PART I of the Annual Report on Form 10-K of TradeStation Group for the year ended December 31, 2005. In reading and evaluating the information set forth in this report, in

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

(a) Sales of Unregistered Securities

During the three months ended March 31, 2006, we issued to 232 employees (including four executive officers) options to purchase
an aggregate of 239,240 shares of common stock. Such options vest ratably in annual increments over a five-year period and are exercisable at prices ranging from $15.54 to $16.58 per share, which was the fair market value (as defined in the
Incentive Stock Plan) of the Companys common stock on the date the options were granted. All of the options were granted under the Incentive Stock Plan in the ordinary course (i.e., annual grants related to 2005 performance), and expire, if
they remain unexercised, on the tenth anniversary of the date on which they were granted.

All the foregoing options were issued by us in
reliance upon the exemption from registration available under Section 4(2) of the Securities Act of 1933, as amended. Other than as described above, we did not issue or sell any unregistered securities during the first quarter of 2006.
