How good is Strategy Tester?

New comment
[Deleted]

How close is the backtesting to the reality?

I backtested my EA on the strategy tester and found several entries shown in the report highly unlikely in real trading.

My ea reentered the market as soon as it was closed, even in the same direction right after being closed by stop-loss.

How can I increase the modelling quality? The number for this experiment was 25%.

Please take a look at the report below (report is also attached) and give me your advice.
