Hi Toof, Re: ...WHAT THE :!@&#$&....

Think of order execution as stacks of orders at each price break. When you enter a new order at a limit, the clerk takes your new order and puts it on the bottom of the pile for that price break. All the orders in the stack above yours will be processed before they get to yours. Then yours will be filled.

Your order for $21.30 was on the bottom of that pile and didn't get filled. As you were entering your Market order (after you had cancelled your Limit order) all the other orders must have cleared their system and you got the next available fill at your $21.34. It's hard to know for certain what the Bid/Ask was at the time of your Fill but you won the Lottery of the Day!

Best wishes,
OAG Tom
