I had just recently that case. Zorro does not call your function in that case, but still the default function since it was declared first and not overridden by the other one. For this reason I've changed also the description in the manual.

For accessing PERFORMANCE elements directly in the g struct, it's g->w.numWin, not g->w->numWin. w is the content, not a pointer.

Many thanks Jcl for the clarification, and what does numwin represent? The number of open + closed winning trades or just the closed ones? In the comment in trading.h it says just 'number of winning trades'

The closed ones. You can find the description of most parameters in the manual under "Trade statistics".

Thank you again! I wasn't sure that variables in the PERFORMANCE struct mapped directly to the one described in the manual in Trade statistics.
