Hi,
I found that under the MC engine of SQ, the execution price of buy/sell next bar at market entry has an error, which is inconsistent with the opening price of the entry bar. The strange thing is that there is a certain probability of occurrence, sometimes correct, sometimes error. The error is several yuan. Backtesting is no problem in MC. In order to facilitate inspection, comparison and calculation, I set spread=0, slippage=0, commission=0.This problem is easy to reproduce
