Yes ( in Tradestation SIM ) This is the difference between Tradestation SIM and Real. In tradestation SIM you get fill as soon as price touches it. I think in IB it wait for 1 tick beyond price to get filled which I think is more realistic. Next week I will try using IB Paper account.
pop & down Edit :11 - I gave myself a 15 minute grace period past my deadline (1:45 EST --> 2:00 EST), but it popped too late for me; also I thought it was going to pop a tad more, so I didn't take the trade in sim either.
