Quote from dagnyt:
What you are describing is not the way it works.
Are you using COMBO to select he options in the spread?
Do you see a bid/ask for the spread? It should be very wide.
If you enter your limit price at something worse than midpoints, you will get filled. It may need a dime worse, or 20 cents worse, or maybe only a nickel worse. A lot depends on which options you are trading.
If they are thin, thin, thin, sans liquidity, they you are at mercy of market makers. If actively traded, and you cannot get a decent fill as I described, then. call customer service and get help with this.
