[amibroker] Re: Simulating adding captial and an intrest setting question

["jamesfarrow2003" <jamesfarrow2003@xxxxxxxxx>]

In case any other newbies out there are interested, this can be done 
using the custom backtester ( see below code).  I am not yet sure if 
this code has any bad side effects, but running it as is produces 
the expected staircase like equity curve ( with interest set to 0)

James

SetOption("UseCustomBacktestProc", True );
SetCustomBacktestProc(""); 

Y = DayOfYear() - Ref(DayOfYear(), -1);

if( Status("action")== actionPortfolio ) 
{ 
   bo = GetBacktesterObject(); 
   bo.PreProcess(); 

   for( bar = 0; bar < BarCount; bar++ ) 
     { 
      bo.ProcessTradeSignals( bar ); 
      if ( Y[bar] < 0) 
       {  
        bo.Cash = bo.Cash + 4000;}
       
      } 
   bo.PostProcess(); 
            
} 

Buy = 0;
Sell = 0;
