The strategies that I test mostly open new trades based on "closing" data. If you wait till open, you can have (1) missed opportunities, (2) trying to place a trade in a more volatile opening market interval, and (3) since your data source does not have opening pricing, you may be out in the...

It depends! What are you trading? Options/stocks/Indexes/...? Liquid/illiquid? What is your objective? When I back test, my goal is to have the back test results closely approximate what I would expect with live trading. So, you need to understand your entry timing (and a "feel" for how much...

Timetwister: This mechanism accesses the complete history (available to quandl). In the example link earliest dividend data is "1993-03-19,0.213" I pull the data down (via a Perl program) and store locally as .csv files, which I then process with my backtest tool. The .csv files can be opened...

Check out "Quandl", they have the data (for free). Below is a code snip for my extraction of dividend data: " $url = 'https://www.quandl.com/api/v1/datasets/SEC/DIV_' .$sym_mod.'.csv?auth_token='.$quandlAuthToken;" Line above is dynamically producing an URL, which is subsequently used to pull...

There is a strong urge and tendency to increase your position size after repeated successes. Use a trade size/money management system that protects you from a disruption in your successes. I have had a number of trades that worked very well for months on end, to then reverse about the time I...

No! SPY & AAPL near month expiry near the money options are heavily traded.

my 2 cents: 40 years ago (or so), when you would crank your automobile on a cold morning, you would typically allow a few minutes for it to warm up and quit sputtering. More recent times, this is less noticeable. The market for thinly trading options seems to exhibit a similar ("amateur? time"...

Tough crowd!

I am unfamiliar with Questrade. You may want to ask them. I use TDA/TOS and I think they exercise if 1 penny or more ITM @ expiration. I can see no reason for ever exercising an option on a liquid product (such as SPY), as you forfeit any extrinsic value and the Commission is typically much...

My 2 cents: The ITM option price = Intrinsic value + Extrinsic value; If you exercise, you forfeit the Extrinsic value. I agree with OptionGuru.

Aston01: Your 1st two paragraphs make sense. I do not follow your final question. Is it your goal to maintain a "delta-neutral" position, after market moves from your originating position? Ie.. do you make adjustments to you position to maintain near delta-neutrality as the market moves? If...

Email thread inquiry and response from TD Ameritrade: ------------------ Thank you for the e-mail and inquiry. I can confirm that we will continue to accept Stop and GTC orders as nothing has changed in light of the NYSE announcement. To clarify further, our order handling system allows us to...

sysdevel99 I have had similar thoughts and experiences.

If you know how to code and are not too picky about performance and capabilities, you can do some back testing in TOS with ThinkScript. There is a good deal of capability, but for my interests, it was too limited. The "example" you post is trivial enough to be done in ThinkScript. If you have...

louisjxn: The following is intended to be helpful and not critical: Do you have a specific plan? How much are you willing to risk. What will be your trade exit, should you realize your trade will fail. What is your target exit, or if no exit, then what is your plan if SBUX moves as you "hope"...

Hm! I liked Bob's response. Concise, to the point, and with link to further info.

Bad idea! Next will they eliminate Market orders? This makes no sense. Either the SEC are idiots, or this is a ploy to push back on the "undisclosed SEC rule filing". (I'm hoping it is the latter) I personally try not to use Stops, since I know what can happen, but I sometimes form similar...

My silly comments: I do not trade futures, so pardon my ignorance: I just looked at OIL ("/CL") in TOS, and observe no March options. <-- Head Scratch #1. /CL options seem to currently be in backwardation, producing an additional headwind against the suggested "Calendar Trades". <-- Is this...

Zestilio : Insufficient clarity of these two statements to evaluate/comment/Code them! 3. swing phase using 3-bar reversal chart must be bullish (i.e. last swing, low or high, is higher than previous) 4. Trend Strength Indicator must score 70 or more (my TSI is total weekly Closes + Highs + Lows...

If I were a gambling man, the Jan 50 Calls could be an interesting long play. Close or roll up if price bounces back up ....
