You can find the commissions in the Commission field in AssetsFix.csv. They are also available on the rate card on the FXCM website.

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?

Today, again. My Zorro script produced a nice entry for NAS100. My script had a stop and a trail. But, I wanted to secure the win and I put a trailing/ Stop order via the Broker platform.
So I was stopped out with 228 EUR win. Zorro html shows -230 EUR as a loss. Does it come with a mismatch of a Zorro "virtuell" trailing stop and the Broker one, which produces a real limit order?

Zorro works perfectly well. I used to work with Pine Script and it cost me ages to programme something which was not even similiar. This issue is a reporting issue only. I would assume that is an issue with the plugin?

For my markets the fees are included inside the spread and as I said commissions are zero.
