Post From: Accurate Trading System Backtesting shows inaccurate order fills

Hello

I am backtesting a trading strategy using the "Accurate Trading System Backtest Mode" on 1 min bars of historical data. Many of the simulated order fills are occurring way outside the price bars. I have attached a screenshot for reference.

My data source is Interactive Brokers. I have set "Intraday Storage Time Unit" to 1 tick and "Number of stored time and sales records" to 10000

My suspicion is that the underlying data contains inaccurate bid/ask values that are not consistent with the OHLC bars. I have tried the Bar Based Backtest but still see inaccurate fills outside the OHLC range. I am unable to solve the problem
