This has occurred to me often; it occurred last week with APP. It occurs for me about once a month when I try to save by using a limit order. APP went from 363 to 380 the next morning so yes it can cost you if you miss a purchase by using a limit order that doesn't execute.
Sometimes, it goes down after you miss buying it too :)
I've not been trading that actively recently, as I used to with FolioFN.
At IB now, I usually use BasketTrader and their MidPrice algorithm, which tries to execute at the midpoint and follows it around.
Typically, most orders get executed in 30 minutes, a few stragglers take up to the rest of the day, and now and then they only get partially filled.
I don't have time to monitor them, so I take what I can get. Executions have seemed good though.
