    If you knew the market was going to turn in a week

    Options are generally priced based on the market's expectation of a move over a given time. Therefore, if you can predict direction, time frame, and size of the move, then you can find an options strategy to maximize that prediction. Unfortunately you've only given a time and direction. Using...

    Quant Cofounder for Options Arbitrage

    Sounds like you've finally learned the first part of what this forum has been trying to tell you all along. Now you need to learn the 2nd part. Why is someone going to want to share the profits from their strategies with you? You must bring something to the table. That's how you break the...

    Connection (login) to broker via TCP with PHP

    I never used mt4, but I thought that was one of those systems where you log in to mt4 and then mt4 connects to the broker. If you need to connect to many different brokers, then you're going to have quite a lot of work ahead of you. Reverse engineering in this context means looking at the...

    Connection (login) to broker via TCP with PHP

    You don't see a webpage when accessing because it's not intended to be accessed by a browser. You're either going to need to use the API provided by your respective broker(s) or reverse engineer their authentication protocol. It shouldn't be too difficult. This should be protected via https...

    Option scraping help

    So the app is run by a client and the client downloads the option data directly or the client downloads option data from your server? If the latter, that's likely to make the fine folks at OPRA unhappy.

    How to do buywrite / sellwrite in IB TWS?

    Or if you don't want to do keyboard shortcuts. Directly to the left of where it shows the margin impact is the "advanced" button. Click that and then select "+Stock Leg"

    Only lose 1%

    If your broker pays interest on cash balance, I wouldn't say it's doing nothing. You could also buy bonds or cds if your broker supports that.

    What is the purpose of overfill protection?

    While I can't say for sure, but consider a case where their order routing system is acting more aggressively. Possibly having orders exist, at least momentarily, on multiple exchanges such that it's in theory to get an overfill. This could increase your chance of getting a fill and possibly a...

    Dynamically exported dialog box (MFC Extension dll)

    I don't see a reference to TakionDialog in the document you linked. I'm assuming the CDialog that it is inheriting from is the CDialog from MFC. If that's the case, then you should read up on creating GUIs via MFC's CDialog class. This is independent of Takion. Just generic Windows MFC dev in...

    Did IB just screw me or was it the exchange?

    TWS has it's problems. Just today I was trying to do a combo order and it wasn't showing me bid/ask prices even though I could see quotes in the options chain in TWS immediately above my order window. I restarted TWS and then it started working. This is not the first time I've had this kind of...

    IB adaptive algo - how effective is it?

    I use adaptive on illiquid option orders occasionally. When I've set it to patient, sometimes it would take maybe 30+ minutes to sort of walk the price up to the limit. However, for example, on Friday I gave it another try on "normal" setting and it appeared to just about immediately set my...

    % ppl who earn >$1 million cumulative from trading over a lifetime?

    The numbers are brought down by those who graduate with degrees in fields that are not well paid. Also consider the people who don't actually utilize their degree or end up in jobs for which no degree is required. Some people are from independently wealthy families and end up not working at all...

    I'm not aware of an OPRA feed that contains it, but if you'd like a specific references: http://cdn.batstrading.com/resources/membership/BATS_US_EQUITIES_TCP_PITCH_SPECIFICATION.pdf Revision History (starts on page 82) specifically page 87 revision 2.36.0. Section 4.3 Add Order on page 20 --...

    A quote feed can include customer vs non-customer flag. Of course this doesn't tell you that it's a MM.

    Opposite you....

    Don't worry about a fill. My orders will be resting (hidden) at the limit prices I post on the exchange I post. Please route there (also as a hidden order at the limit price) so that we can be counter parties (just don't cross streams)! I was going to post a trade in an illiquid underlying such...

    Opposite you....

    Will you be doing equity options and will you route to the exchange of my choosing? If so, I'll gladly tell you which trades I'm doing ahead of time so that you can do the opposite. ;)

    Crypto will never replace normal currency

    Your knowledge of computers should be supplemented by knowledge of economics. While it is true that power consumption could grow unbounded, it is also true that this should only happen as long as it is economically feasible to do so. Granted there can be a speculative element to this, but what...

    Anyone know what time VIX options settle today

    The VIX settlement price is calculated from the SPX options that expire 30 days out, which means they need a value to use for each contract. The individual contract prices used, as far as I understand, is calculated based on a market opening auction that's effectively crossing the OPG orders...
