^^^ I see, I tend to mostly sell way OTM puts (not much premium collected) or do covered calls (not very close to ATM). I often pick prices between the bid and ask and often have to make adjustments (cancel, then replace w/a new order). TOS and TD AM also have this, which I like and use all the time: I'm also a little concerned about the bust/adjustment fees (http://individuals.interactivebrokers.com/en/p.php?f=otherFees). On TD AM, I've had some erroneous trades go through long ago, which were canceled. I received notification of "ORDER FILLED IN ERROR". It's very rare and wasn't my fault. They were (stock) limit orders I'd placed. It almost looks like with IB I could be on the hook for $250-500, if that happens.
