Thanks for the reply. Yes, I am aware, but the comissions for my traded instruments are zero, see:

The AssetsFix file was updated via the API of FXCM (and my Broker does not show any commissions for this trades)

I could find a possible reason for the wrong profit in the html sheet. I recognised it several times when I manually stop the position. Again, today I closed manually a Long position with a little win, Zorro shows a loss with almost the same amount.
Therefore, the issue I recognised seems to be for Long and Short positions with a manual close.

When I do not close it manually and it will be stopped out by the Zorro script, it seems to work correctly. Is there a possible issue with the plugin for FXCM?
