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 |

Correction, it seems bar based back testing is showing reasonable fills on bid/ask. I think I will stick to this method for now as I am only testing on 1 min bars. It seems the historical bid/ask data form Interactive Brokers is just wildly inaccurate

Sierra Chart Historical Data Service is not enabled on my package. What's up with that?
