tplast - ditto exactly. I've even watched the quoted bid drop below my LMT price for the spread - I have never ever received a fill on the ES or NQ emini futures options using a GLOBEX spread. It may be specific to this product but who cares really.
Just my experience but it works better for me to enter one option at a time during a quiet consolidation period - maybe lunchtime or a weak low vol day. If the damn price stays still then I can test the water, drop it a nickel, and so on. If it's moving all over the place then it's possible to spike and kill my spread all together.
For a vertical I just buy the long option, then buy the short option. I don't want to have a naked short for even an instant in case of any freak event. I don't want to buy all 5 long options at once either for the same reason. But since I'm entering during a quiet period I can do this whole thing pretty quickly, one at a time. It will be a major pain in the ass to put on 10 butterflies like this but what the heck what else do I have to do during a trading day?
I'd love to hear more on this from anyone using IB.
Lotsa luck
