To give an example, what I'm doing is simply:
Code:
if(is(EXITRUN)) 		
  	for(all_trades) 
  		print(TO_CSV, "%s, %s, %.1f, %.2fn", strdate("%y%m%d %H:%M:%S", TradeEnterTime), Asset, SpecialKey, TradeProfit);

Means after the last run Zorro prints to CSV each trade together with a special key number (TradeVar). No restart of run or what ever, only printing trade results to CSV.

Or like MatPed said: you are not forced to use this function.
