Does this help? Chart is PUT Theta for that series. A short vertical in the range of the BOX will have positive Theta, else, not-so-much! -- your position extends into the "not-so-much" region.

1) Do you only require EOD data? -- or finer granularity, such a minute? - Costs range from free, to > $20K for data. (how much history do you require? -- 180 days, 10 years, ...?) 2) Will you develop your software, or do you want someone to develop for you? Your request seems vague, but...

I am presenting observations I have made regarding option limit orders on "not so liquid" options. I have no idea what you may be observing, as you are not providing specific examples. It is also unclear if you understand Level II quotes or use them to better understand what is happening...

Apparently you failed to comprehend my post. Look at what happens prior to your order, then look what happens after placing/modifying your order. For example, if you at trying to trade the 76 PUT strike for the 15 SEP 17 IWM, you should be able to observe something like the following, which...

can you identify the underlying and the options (opra). Also, did you notice the bids/asks and Bid size and ask size movement? -- I have observed some automatic tracking of my orders that may be related to your observances. -- This was some time back for products I no longer trade, such as...

ASK < BID <-- Red flag, bad data! There is NO bids for that option in TOS. Apparently the BID column is populated with excrement in your pic.

I understand more now. My thinking is your "Java" code is your secret sauce which is being refined, and you need to reduce the manual effort (and possible introduction of errors) in relating that back to the "connection" to the Alert/Real-time data (this update needs to be as "no-touch" as...

I think he realizes that from his comment "involve leaving a computer running 24/7 and connected to a datafeed to actively monitor". He would prefer all tracking be handled by broker's servers, which still seems possible.

Curious: Is the algorithm for determination of the price levels at which you desire the Alerts a homogeneous form, such that it may be coded (derivation of the desired price level criteria) over the entire relevant WatchList, such that that does not have to be altered with each new watchlist...

See my first post. I suspect there may be a way!

There are ways to "roll your own", but likely you are seeking more "low hanging fruit" than that would entail.

You may wish to post your question on TOS->Support/Chat->Chat Rooms->thinkScript Lounge: IF possible to import Alerts into TOS, someone there will know. Don't mention App or IB, etc if you expect response and not get censored.

Can you open a brokerage account at TD Ameritrade? (for access to TOS)<- permanent solution Seems you were using tool on Investools' site. A link to test for 60 days: "https://www.thinkorswim.com/t/pm-registration.html#?prospectType=o"

I have a Dividend trade that I would like to sell you! Pick a security that has profited the prior 8 Dividend periods, and assume the next will be profitable! The fallacy is you snare yourself in your ill-conceived reasoning! <-- Note if the prob is 50/50, it is actually 50/50, regardless of...

Seems you may have observed something, that prompted this thought process. Without observing what prompted this, any comments from me would be WAGs. Pricing errors (my take on your comments) may not be actionable unless adequate market exists (adequate volume {or at least open interest and...

IMO: There are so so many approaches (most of which have serious flaws), finding one or more that is agreeable to your own "criteria" is mind-numbing! The most difficult task being determining what your own "criteria" is in sufficient actionable terms! I now trade SPX Road Trip Trades, which...

IMO: Many smart people are developing strategies to locate, then exploit "opportunities" (or edges) in the market. This process, by its nature morphs the market, by increasing competition on exploiting those cases until the "edge" dissipates. To remain profitable, strategies will need to...

Check with your TAX guy! For example, if the position is an SPX contract (a section 1256 contract), I think it will be 60/40 (long term/short term) regardless of the time held!

I "have noticed" the "Portfolio, Beta Weighted" option for the Risk Profile, but I do not understand what that really does, and have no plausible theory of how that would provide me with useful information. Perhaps my ignorance! Regarding the single X-Axis, I think I failed to convey to you an...

i960: Thanks. I knew I had seen that before, but my memory keeps leaking out somewhere! Many thanks for you guys helping an old forgetful fart.
