"In real life, you'd see spreads like AMZN 04/13/2017 910.00 C 4.90 +1.67 Bid: 4.75 Ask: 5.20 (with AMZN @ $897 right now) and the fill you'd get on the buy side would be closer to the ask. i.e. I'd offer $5.00 and hope that it filled.  Filling a $4 bid when ask is $8 isn't likely unless the stock blipped down enough for your price to fill.  Options are a lot like day trading, in most cases. Most members here will agree that day trading isn't investing, it's gambling. Long term, the S&P has been up 10%/yr. But any given day, the noise of the market is a 50/50 zero sum game. Most long term stock 'investors' do well. Those who get in and out, not so much.  There are aspects to options that are appealing. As you've seen, the return can be high, even IRL, but your loss can be 100% as well. Let me share with you a blurred line - I wrote ""Betting on Apple at 9 to 2"" in which I described an option strategy that ran 2 years and would return $10,000 on a $2200 bet. A similar bet that ended a year ago yielded a 100% loss. I don't post there very often, as I keep that trading to a minimum.  There are warnings for those who want to start trading options -"
"4PM is the market close in NYC, so yes, time looks good.  If ""out of the money,"" they expire worthless.  If ""in the money,"" it depends on your broker's rules, they can exercise the option, and you'll need to have the money to cover on Monday or they can do an exercise/sell, in which case, you'd have two commissions but get your profit.  The broker will need to tell you their exact procedure, I don't believe it's universal."
"All else being equal, you should look for more volatile (riskier) stocks. Technically, it was all time value - the entire value of an ""out of the money"" option is time value.   What's confusing is that time value is affected by numerous variables, only one of which is time. The reason volatility is the one to look at is that all the rest are likely already intuitive to you, or are too minor an influence to worry about: Current risk-free interest rates and a stock's dividend payout during the life of the option affect the value of the call, but are usually minor infulences.   (Higher interest rates makes call values higher, and higher dividend yield makes call values lower.) Longer time to expiration will increase the value of the call, but you're pretty likely already focused on that. The strike price's proximity to the current price affects the call's value - agreeing to sell a stock 5% above current levels will pay more than agreeing to sell it 10% above current levels - but again, this is likely obvious to you. Volatility, or the percent by which the stock is likely to move up or down on a given day, is almost certainly the variable that's not already obvious. Stocks that jump all over the place have higher volatility than those that move more predictably.     The reason that options (calls and puts) cost more on higher volatility names is that options' payout is asymmetrical.  In the case of calls, the option holder gets all the upside, but none of the downside, other than what they paid for the opotion.     If one stock goes up or down $5 every day, and another goes up or down $20 every day and you could pay some fixed amount to get that stock's upside, but not have any exposure to its downside, other than that fixed amount, you'd pay more for the one that pays you $20 or $0 than you would for the one that pays you $5 or $0.    That's why higher volatility (meaning larger daily moves) makes optimum prices higher."
The type of day trading you have described is a form of gambling.  As with any type of gambling, sometimes you win.  Doesn't mean you are good at it or will win next time. As long as you clearly understand that you are doing it for fun, I think your current strategy is fine.  If bankruptcy is on the table, you need to stop now.
Yeah man, was basically just screwing around.  Day-trading stocks is a bit different for me.  I usually trade options.  Taking a bit getting used to.  Not to mention, I probably lost a good bit on spreads.  I made all market orders lol.
"ETFs are well suited to day trading, but you should be mindful of the bid-ask spread. See article: Commission-free ETFs are a great way to save money, but watch the bid-ask spread too. Bid-ask spread is largely a function of liquidity, or the volume of   buyers and sellers for an asset during a particular moment in time.   ... It may be more difficult to trade certain assets that are less   liquid, where bid-ask spreads can be higher. Think some penny stocks. If you have the choice, compare the spreads of the ETF and the target stock. Longer-term ""keep & hold"" trading on ETFs tracking futures can be somewhat disadvantageous.  Futures contracts roll-over every month.  Exchange traders have to sell and buy in on the next contract.  ETFs don't reflect the price differential between the futures contract. See here for more detail on that: Positioning For An Oil ETF Rebound? Watch For Contango Contango occurs when the price on a futures contract is higher than   the expected future spot price, which creates the upward sloping curve   on future commodity prices over time. Essentially, the phenomenon   reflects a current spot price that is lower than the futures price.   ... While this phenomena is a normal occurrence in the futures market,   contango can have a negative effect on ETFs."
Marketwatch reports that the 108 strike call option sells for 1.45,  down 1.53 from yesterday. If we split the bid and ask you get 1.415. That is what that contract will, likely, trade at.  The biggest problems with options are commissions and liquidity. I have seen a commission as high as $45 per trade. I have also seen open interest disappear overnight. Even if you obtain contracts that become worth more than you paid for them you may find that no one wants to pay you what they are worth.  Track your trade over a few weeks to see how you would have done. It is my experience that the only people who make money on options are the brokers.
"Day trading is an attempt to profit on high frequency signal changes. Long term investing profits on low frequency changes. What is the difference? High Frequency Signal = the news of the day. This includes things like an earnings report coming out, panic selling, Jim Cramer pushing his ""buy buy buy"" button, an oil rig blowing up in the ocean, a terrorist attack in some remote region of the globe, a government mandated recall, the fed announcing an interest rate hike, a competitor announcing a new product, hurricanes, cold winters, a new health study on child obesity, some other company in the same sector missing their earnings, etc. Think daily red and green triangles on CNBC: up a buck, down a buck. Low Frequency Signal = The long term effectiveness of a company to produce and sell a product efficiently plus the sum of the high frequency signal over a long period of time. Think 200 day moving average chart of a stock. No fast changes, just, long term trends. Over time, the high frequency changes tend to negate each other. To me, long term investing is wiser because the low frequency signal is dominated by a companies ability to function well over time. That in turn is driven by the effectiveness of its leadership coupled with the skill and motivation of its employees. You are betting on the company and its people. Pseudo-random shorterm forces, which you can't control, play less of a role.  The high frequency signal, on the other hand, is dominated by sporadic and unpredictable forces that typically can't be controlled by the company. It has some tinge of randomness about it. Trying to invest on that random component is not investing at all, it is gambling (akin to ""investing"" in that next coin flip coming up heads) I understand the allure of high frequency trading. Look at the daily chart of a popular stock and focus on the up and down ticks. Mathematically, you could make a killing if you could just stack all those upticks on top of each other. If only it was that easy."
Yeah, that's what I hear.  I was mostly just screwing around today.  I'm an options trader which allows me to make a bit higher returns.  I really don't like the setup interface this thing uses, and I ended up just trading market orders for the hell of it all day.  I made about 3% today. Still learning the interface and how to maximize use.
"As I stated in my comment, options are futures, but with the twist that you're allowed to say no to the agreed-on transaction; if the market offers you a better deal on whatever you had contracted to buy or sell, you have the option of simply letting it expire. Options therefore are the insurance policy of the free market. You negotiate a future price (actually you usually take what you can get if you're an individual investor; the institutional fund managers get to negotiate because they're moving billions around every day), then you pay the other guy up front for the right of refusal later. How much you pay depends on how likely the person giving you this option is to have to make good on it; if your position looks like a sure thing, an option's going to be very expensive (and if it's such a sure thing, you should just make your move on the spot market; it's thus useful to track futures prices to see where the various big players are predicting that your portfolio will move). A put option, which is an option for you to sell something at a future price, is a hedge against loss of value of your portfolio. You can take one out on any single item in your portfolio, or against a portion or even your entire portfolio. If the stock loses value such that the contract price is better than the market price as of the delivery date of the contract, you execute the option; otherwise, you let it expire. A call option, which is an option to buy something at a future price, is a hedge against rising costs. The rough analog is a ""pre-order"" in retail (but more like a ""holding fee""). They're unusual in portfolio management but can be useful when moving money around in more complex ways. Basically, if you need to guarantee that you will not pay more than a certain per-share price to buy something in the future, you buy a call option. If the spot price as of the delivery date is less than the contract price, you buy from the market and ignore the contract, while if prices have soared, you exercise it and get the lower contract price. Stock options, offered as benefits in many companies, are a specific form of call option with very generous terms for whomever holds them.
No one at my firm uses python, but we have both long-term algo-managed portfolios as well as very successful day trading strategies. I've worked a bit with both, so if you have any questions I'd be happy to try and answer them and if I can't I'll ask at work next week.
"At my soon to be legendary Stock Options Cafe, I recently wrote an article ""Betting On Apple at 9 to 2.""  It described a trade in which a 35% move in a stock over a fixed time (2 years) would result in a 354% gain in one's bet. In this case, the options serve to create remarkable leverage for speculators. In general, option help provide liquidity and extend the nature of the risk/reward curve.  There are option trades that range from conservative (e.g. a 'covered call') to wildly speculative, as the one I described above."
"You'd need to know the delta and the theta of the option. You can either calculate them yourself using a model like Black-Scholes (assuming you have a market price and can imply a volatility, and know the other factors that go into the model) or, you can see if your broker quotes ""greeks"" as well (mine does). The delta is the sensitivity (rate of change in value) to the underlying stock price, and the theta is the sensitivity to time passing (usually expressed in $/day).  So if your option has a delta of .5 and a theta of -.04, when one day passes and the underlying stock goes up $3, the option will gain roughly $1.50 due to the underlying stock price and lose $0.04 due to time passing."
"There is a white paper on ""The weekend effect of equity options"" it is a good paper and shows that (for the most part) option values do lose money from Friday to Monday. Which makes sense because it is getting closer to expiration. Of course this not something that can be counted on 100%.  If there is some bad news and the stock opens down on a Monday the puts would have increased and the calls decreased in value. Article Summary (from the authors): ""We find that returns on options on individual equities display markedly lower returns over weekends (Friday close to Monday close) relative to any other day of the week. These patterns are observed both in unhedged and delta-hedged positions, indicating that the effect is not the result of a weekend effect in the underlying securities. We find even stronger weekend effects in implied volatilities, but only after an adjustment to quote implied volatilities in terms of trading days rather than calendar days.""  ""Our results hold for puts and calls over a wide range of maturities and strike prices, for both equally weighted portfolios and for portfolios weighted by the market value of open interest, and also for samples that include only the most liquid options in the market. We find no evidence of a weekly seasonal in bid-ask spreads, trading volume, or open interest that could drive the effect. We also find little evidence that weekend returns are driven by higher levels of risk over the weekend.  ""The effect is particularly strong over expiration weekends, and it is also present to a lesser degree over mid-week holidays. Finally, the effect is stronger when the TED spread and market volatility are high, which we interpret as providing support for a limits to arbitrage explanation for the persistence of the effect."" - Christopher S. Jones & Joshua Shemes You can read more about this at this link for Memphis.edu"
Options are a derivative product, and in this case, derive their value from an underlying security, a traded stock. An option gives you the right, but not the obligation, to buy a stock at a given price (the strike price) by a given time (the expiration date.) What I just described is a call option. The opposite instrument is a put, giving you the right, but not the obligation, to sell the stock at a given price.  Volumes have been written on the subject, but I'd suggest that for a custodial Roth, I'd not activate the ability to trade options.  How to get started with options investing? offers a nice introduction to trading options. In my response, I offer an example of a trade that's actually less risky due to the option component.
(Note: I am omitting the currency units. While I strongly suspect it's US$ I don't know from the chart. The system works the same no matter what the currency.) A call or a put is the right to sell (put) or buy (call) shares at a certain price on a certain day. This is why you see a whole range of prices. Not all possible stock values are represented, the number of possibilities has to be kept reasonable. In this case the choices are even units, for an expensive stock they may be spaced even farther apart than this. The top of the chart says it's for June. It's actually the third Friday in the month, June 15th in this case. Thus these are bets on how the stock will move in the next 10 days. While the numbers are per share you can only trade options in lots of 100. The left side of the chart shows calls. Suppose you sell a call at 19 (the top of the chart) The last such trade would have gotten you a premium of 9.70 per share (the flip side of this is when the third friday rolls around it will most likely be exercised and they'll be paying you only 19 a share for a stock now trading at something over 26.) Note the volume, bid and ask columns though--you're not going to get 9.70 for such a call as there is no buyer. The most anybody is offering at present is 7.80 a share. Now, lets look farther down in the chart--say, a strike price of 30. The last trade was only .10--people think it's very unlikely that FB will rise above 30 to make this option worthwhile and thus you get very little for being willing to sell at that price. If FB stays at 26 the option will expire worthless and go away. If it's up to 31 when the 15th rolls around they'll exercise the option, take your shares and pay you 30 for them. Note that you already gave permission for the trade by selling the call, you can't back out later if it becomes a bad deal.
Put options are contracts to sell. You pay me a fee for the right to put the stock (or other underlying security) in my hands if you want to. That happens on a specific date (the strike date) and a specified price (the strike price). You can decide not to exercise that right, but I must follow through and let you sell it to me if you want to. Put options can be used by the purchaser to cap losses. For example: You purchase a PUT option for GE Oct19 13.00 from me. On October 19th, you can make me let you sell your GE stock to me for $13.00 a share. If the price for GE has fallen to $12.00, that would be a good idea. If its now at $15.00 a share, you will probably keep the GE or sell it at the current market price. Call options are contracts to buy. The same idea only in the other direction: You pay me a fee for the right to call the stock away from me. Calls also have a strike date and strike price. Like a put, you can choose not to exercises it. You can choose to buy the stock from me (on the strike date for the strike price), but I have to let you buy it from me if you want to.  For example: You purchase a CALL option for GE Oct19 16.00 option from me. On October 19th, you can buy my GE stock from me for $16.00 a share. If the current price is $17.50, you should make me let you buy if from me for $16.00. If its less than $16.00, you could by it at the current market price for less. Commonly, options are for a block of 100 shares of the underlying security. Note: this is a general description. Options can be very complicated. The fee you pay for the option and the transaction fees associated with the shares affects whether or not exercising is financially beneficial. Options can be VERY RISKY. You can loose all your money as there is no innate value in the option, only how it relates to the underlying security. Before your brokerage will let you trade, there are disclosures you must read and affirm that you understand the risk.
I am going to. Like I said I have not traded options much in general, but I can see a lot of potential in derivatives in general, and it makes me kind of grin. In the case of commodities, the advantages are really apparent. The only problem I see with stock options is that they expire, and thus if you are more long term bull on a stock, it would be harder. But for things like commodities, that are shorter term any ways and require margin, it makes a lot of sense IMO. I could see how you could gain a larger diversification through options (being able to bet on Russell 2000, S&amp;P, etc. ) or esoteric markets (electricity).   I will look up that book that you mentioned. Thanks man.
If you're talking about just Theta, the amount of decay due to the passage of time (all else being equal), then theoretically, the time value is a continuous function, so it would decay throughout the day (although by the day of expiry the time value is very, very small).  Which makes sense, since even with 15 minutes to go, there's still a 50/50 shot of an ATM option expiring in-the-money, so there should be some time value associated with that one-sided probability. The further away from ATM the option is, the smaller the time value will be, and will be virtually zero for options that are deep in- or out-of-the-money. If you're talking about total time value, then yes it will definitely change during the day, since the underlying components (volatility, underlying price, etc.) change more or less continuously.
http://dailyfinance.com Enter a stock ticker, then click on the Chain link to the left. Then, click on the option tickers to see their charts. EDIT: the site has changed, and there are no more option charts. So why are option charts so tough to find? Options are derivatives of the stock. Option prices are defined by a formula. The inputs are stock pricxe, strike, days to expiration, dividend, risk-free interest rate, and volatility. Volatility is the only thing that cannot be easily looked up. With a Black-Scholes calculator, and some reasonable volatility selections, it's possible to make your own fairly accurate option chart. I don't think it's very enlightening, though. The interesting things are: the stock price movement (as always), and the nature of option pricing behavior in general (understanding how the formula represents crowd behavior).
I don't call myself a daytrader.  My ideal timeframe is from a few days to a couple weeks, sometimes even longer.  So swings will always be my priority, but I do daytrade futures/forex outside of regular hours and equities when I'm not doing a swing.  Platform is really only important when you realize what you need from it.  If you're doing plenty of tickets, commissions will play a larger role the more you trade.  Some brokers are more bare-bones, some have more technology/tools.  If you're just learning, you typically don't want to put on extra expenses, but as you start making money, you'll want to go with a broker that minimizes your costs while using a third party for whatever tools you need.
Looking at the SPY option chain you posted, all of the call options with a strike price of 199.50 or higher have a bid of N/A.  That's because the ask price for all of those options is 0.01, and the bid price has to be less than the ask price, but buyers are not allowed to bid 0.00.  It's not accurate to say that no one wants to buy those calls - anyone who wanted to buy one of those calls would just buy it at the ask price of 0.01. So why are people selling those calls for just 0.01?  The further out of the money you go as you get closer to expiration, the less likely the underlying stock or ETF (SPY in this case) will go over the strike price, and the less you can sell it for.  SPY closed yesterday at about 195, and it would have to go up almost 2.5% today for the 199.50 calls to be in the money, and a 2.5% move in one day is extremely unlikely.
"Why bother with the ETF? Just trade the options -- at least you have the ability to know what you actually are doing. The ""exotic"" ETFs the let you ""double long"" or short indexes aren't options contracts -- they are just collections of unregulated swaps with no transparency. Most of the short/double long ETFs also only attempt to track the security over the course of one day -- you are supposed to trade them daily. Also, you have no guarantee that the ETFs will perform as desired -- even during the course of a single day. IMO, the simplicity of the ETF approach is deceiving."
If the SEC were to ask, the broker would have to say 'yes' or 'no' concering if you established a pattern of daytrading at that brokerage. Suppose you make the 4 roundtrips and then you make a 5th that triggers the call. The broker will call you up and say you either need to deposit enough to bring your account to $25k or you need to never make another daytrade at that firm... ever! That's the only warning you'll ever get. If you're in violation again, they lock your account to closing positions until you send in funds to bring the balance up to $25k. All you need to do is have the money hit your account, you can take it right back out again. Once your account has $25k, you're allowed to trade again.... even if you remove $15k of it that same day. If you trigger the call again, you have to send the $15k back in, then take it back out. Having the label is not all bad... they give you 4x margin. So with $25k, you can buy $100k of marginable stock. I don't know... that could be a bad thing too. You could get a margin call at the end of the day for owning $100k of stock when you're only allowed to own $50k overnight. I believe that's a fed call and its a pretty big deal.
