Tester b 200 problem

 
Hi slawa,
I have two adjacent time interval : [t1,t2] and [t2,t3] (for sample september and october)
Backtest result on [t1,t2] = A
Backtest result on [t2,t3] = B
Backtest result on [t1,t3] = C
All with 90% quality.

The problem is that A+B != C, and not a little difference : a huge difference !
In any case, the EA close all trades just before t2, so, it's not a problem of closing trades at the end of test. The numbers of trades are corrects.
Of course there is no compounding of the lots.
Do you have any idea ?

Thanks a lot,
Michel
 
What the initial deposit in the [t2,t3] case? I suspect it differs from deposit at the t2 in the [t1,t3] case

Yes, both deposits are different, but this is not the point as there is always enough margin and the lots are constant, they are not balance or equity dependent.
What I did is to delete all my History and Tester folders and then redownload a hopefully clean history. Since that, the problem seems to be corrected.

Anyway, thanks for your time.
Regards,
Michel
