Hi there, I was trading QQQ this morning and encountered something bizarre. Market was trading around 34.9-ish, and I entered in a Stop entry to short at: 35.24. With everything set up, I sat around watching the marke for maybe 10 minutes. Right before I was heading off, my stop was suddenly triggered! I was triggered and got a short position at $34.80. My short sell stop is at $35.24, and the prices were *nowhere* near there! Are stops just generally unreliable through IB? Does this happen often? Does anyone have any ideas why it would happen? Thanks for your help.
