Looking for any clarification, please. Was short CASY at 27 yesterday. Put a buy-stop in at 27.68 gtc after I got filled short. I check this morning for an update and see that my stop-loss was filled at 27.46, the HOD - so far. I know the bid/ask spreads get a little wide pre-market but should I have been filled here when the stock never traded up to my buy-stop, 27.68. My broker said once my ask was hit, my order became a mkt order; thus, I was filled at 27.46. I must be missing something here 'cause this does not make much sense to me.
