Hello Petko, I have only been testing Expert Advisor Studio for about 10 days and I am very impressed! Unfortunately, I have the problem that when I import strategies generated a few days ago via “Strategy” > “Import to Expert Advisor back”, the performance metrics of the backtest often differ by several hundred percent. Example: before the profit per day was $5.87, now it is $ -2.21. How can this be?

My setup is identical. I use the MetaTrader4 demo data, trading hours are identical.

I am happy about every hint!
