Is there a variable to check how much Margin is currently in use?

It might be related to ProfitOpen, but I'm not sure

I didn't find anything here: http://manual.zorro-trader.com/winloss.htm
And since my trades have different margins, I cannot simply multiply the number of trades with the current margin. That's why I'm asking.

Ok, I'm currently using this one:

var MiU = 0;
for(open_trades)
MiU += TradeLots*MarginCost;

(Tradeloops are pretty handy )

It's "MarginVal". The manual has a search function, so if you look for something particular, just enter a keyword like "margin".

Hmm, MarginVal does not seem to work:
Error in 'line 135:
'MarginVal' undeclared identifier
< plot("MiU2",MarginVal,1,BLACK);
>.

By the way, where is that search function jcl mentioned?

@blaub4r
MarginVal didn't work for me too. Just didn't bother to mention it.

I always search via google:)

Yes, sorry. It's "MarginSum", not "MarginVal". For some reason the variable was renamed some time ago. Here's the updated manual page:

Search is when you click on the tab named [Search]. All Zorro variables are also listed in the file variables.h in the include folder, so that's a fast way to look for a certain variable.
