Hi - thanks for your response.
I already read this forum but could not really find an answer. Out of a couple of reasons:
I cannot open half a position or similar as I don't know in the beginning of my trade how many shares I would like to sell.
I don't use the TICK flag as this is not the focus of my strategy.
The solution would be probably a TMF - but I could not find the way to implement it. I can close the position in a TMF, that's fine. But I cannot say how to close a quarter or half of the postion.

I'm really interesting why the function exitTrade is not working as desribed in the manual. Maybe I got it wrong?
