Re: OneChicago, LLC Rule Submission

New OCX Rule 516 & NTM 2015-7 

(OCX Submission Number 15-002)

Dear Mr. Kirkpatrick:

Pursuant to section 5c(c)(1) of the Commodity Exchange Act, as amended (the “Act”), and § 

40.6(a) of the regulations promulgated by the Commodity Futures Trading Commission 

(“CFTC” or the “Commission”) under the Act, OneChicago, LLC (“OneChicago,” “OCX,” or 

the “Exchange”) hereby submits the following rule amendment and associated Notice to 

Members (“NTM”) 2015-7, which will become effective on April 6, 2015.

OneChicago is proposing to amend its Rulebook to add new OCX Rule 516. New OCX Rule 

516 will codify the requirement that OneChicago Clearing Members submit to the Exchange 

account information related to reportable positions in OneChicago Contracts. OneChicago 

currently requires such reporting, but has not previously codified this requirement in the OCX 

Rulebook. 

OneChicago is concurrently issuing NTM 2015-7. The purpose of NTM 2015-7 is to make 

market participants aware of new OCX Rule 516. Additionally, NTM 2015-7 informs market 

participants that OneChicago will require firms to submit Form 102 data to the Exchange 

electronically. The NTM then describes how firms will be expected to report Form 102 data to 

the Exchange electronically. Finally, the rule amendment amends the contract specifications for 

each OneChicago product to provide the reportable trading volume, which the CFTC’s new 

Ownership and Control Reports (“OCR”) rule has defined as 50 or more contracts during a 

single trading day.

The purpose and effect of the rule amendment NTM is to inform market participants of new 

OCX Rule 516 and to require market participants to submit Form 102 data to the Exchange 

electronically, in a manner generally consistent with the CFTC’s OCR rule. Comments on this 

NTM have not been solicited and none have been received. OneChicago is not aware of any 

substantive opposing views to this NTM. OneChicago certifies that the NTM complies with the 

Act, including the core principles, and the Commission’s regulations promulgated thereunder. 

OneChicago further certifies that a copy of this submission has been posted on the OneChicago 

website. 

OneChicago staff has reviewed the core principles applicable to designated contract markets 

(“DCMs”), and has concluded that the proposed NTM may have some bearing upon the 

following core principles: 

Core Principle 4: Core Principle 4 requires that a DCM have the capacity and responsibility to 

prevent manipulation, price distortion, and disruptions of the delivery or cash-settlement process 

through market surveillance, compliance, and enforcement practices and procedures, including: 

(a) Methods for conducting real-time monitoring of trading; and (b) Comprehensive and accurate 

trade reconstructions. 

Core Principle 5: Core Principle 5 requires that a DCM adopt position limitations or position 

accountability to reduce the potential threat of market manipulation or congestion.

This rule amendment and associated NTM supports Core Principles 4 and 5 in that it furthers 

OneChicago’s ability to meet its self-regulatory obligations.

If you have any questions or comments related to this filing, please feel free to contact me by 

telephone at (312) 424-8524 or through e-mail at wbarazi@onechicago.com. 

Respectfully Submitted,
