[amibroker] Alter PointValue() in AFL - not working

[dralexchambers]

Hi,

I'm using the Custom Backtester Code to alter PointValue for each 
trade. I intend to alter the PointValue for each trade according to 
Equity and a few other calculations.

I tried the code below and it isn't working. I'm setting PointValue 
to an arbitary number (300) just to test the code, and plotting the 
PointValue to see the output.

Can anyone suggest - thanks.


SetCustomBacktestProc(""); 

if( Status("action") == actionPortfolio )
{
  bo = GetBacktesterObject();
  bo.PreProcess();
  for( bar = 0; bar < BarCount; bar++ )
  {
   CurrentPortfolioEquity = bo.Equity;
   for( sig = bo.GetFirstSignal( bar ); sig; sig = bo.GetNextSignal( 
bar ) )
    {
    sig.PointValue = 300;
    }
   bo.ProcessTradeSignals( bar );
  }
  bo.PostProcess();
}

Plot(PointValue,"PV",colorGreen,styleDots|styleOwnScale);
