I didn't realize until I came home and reviewed the days logs that I was RAPED and PILLAGED by Tradestation this morning. My stop market (simulated using their trading automation) was triggered at 09:12:19 AM and was filled at 674.3. When I got the email notification the price was around there so I didn't realize what had occurred. When I checked the Time and Sales logs I see the price was between 678 and 679 at that time. At best a $400 difference. I called and was told they'll call me back, but that I should always call right away. I didn't ask if that meant: 1. call right away after every trade 2. only call after those trades where I'm raped? 3. only call after those trades where I'm filled $400 away from the current market price? Can anyone help clarify? Did this happen to anyone else?
