My results with the Every Tick model are not the same when I use the Open Prices Only model. Why is that?

The big difference between the two test models is the order opening time.

In the Open Prices Only model the orders are  opened only at the beginning of each candle, and indicator checking is done at the previous candle close. Also, moving stop loss (SL) to break even (BE) and trailing stop loss adjustment is  done only at that time.

In Every Tick model, on the other hand, entry checks are made 20 minutes before the candle close and indicator checking is done on the most current candle. And SL to BE and trailing SL are checked every minute and adjusted if necessary.
