[amibroker] Custom Trade Metrics

["C Alvarez" <yahoo@xxxxxxxxxxxx>]

I am trying to add the custom metric of what the Historical 
Volatility was when the trade was entered. 

I tried the following code, but all I get are blanks. Do we not have 
access to the price arrays? Or what am I doing wrong?

Thank you,
Cey

Here is the code:
SetCustomBacktestProc(""); 
if( Status("action") == actionPortfolio ) 
{ 
   bo = GetBacktesterObject(); 
   bo.Backtest(1); 
   for(trade=bo.GetFirstTrade(); trade; trade=bo.GetNextTrade()) 
   { 
           HVtrade = 100* StDev(log(C/Ref(C,-1)),100)*sqrt(250);
	   trade.AddCustomMetric("HV", HVtrade);
   } 
    bo.ListTrades(); 
}
