Recently i started to trade TF again (1 lot) and I place a stop loss. When the stop loss triggered, it executed 6 ticks above my stop loss price. So my questions are: 1. Is TF (Russell 2000) such a thin market? 2. Where does IB held their stop loss order? in server-client or client-side? 3. Is this a broker issue or does it happen to broker like Tradestation too?
