what is this ?

Discussion in 'Options' started by silver217, May 1, 2012.

  1. At Interactive Brokers I placed a limit combination order:

    SELL 6x SPXPM june 1500
    BUY 6x SPXPM june 1510

    for a limit price of 0.45 (credit)

    At setting up the combination order I have 2 choices: SMART and CBOE2
    I choose CBOE2, there is only one place where these options are available
    so there is nothing smart. right ?

    Before I transmit the order, the Bid size is 138, Bid = 0.30, and
    the Ask size is 186, Ask = 0.70

    After I placed the order the Ask size becomes my size of 6 and also my
    limit is now the new Ask. No fill yet.

    Can sombody explain this to me ?

    You usually don't get filled right away with limit orders bro, be patient...
  3. if i understand your sit correctly, this is what happens in illiquid options - the b/a "magically" changes after you put in your order. there is no way around this except to stick to liquid options.

  5. It sounds like you put in the best offer and haven't been filled yet. Am I missing something?
