Thanks to everyone who replied, you have been a big help and I now have it working. The problem was that the custom metric must be defined AFTER calling the CBT.
The code below works but is still a messy solution as I want to vary the number of columns from application to application. With each change I now have to edit two programs. I was hoping for a simpler general solution to add Columns to the regular Backtester report.
have a great day,
Herman
SetOption ( "UseCustomBacktestProc", True );
if ( Status( "action" ) == actionPortfolio )
{
bo = GetBacktesterObject();
bo.PreProcess();
for ( bar = 0; bar < BarCount; bar++ ) bo.ProcessTradeSignals( bar );
bo.PostProcess();
bo.AddCustomMetric( "Close", StaticVarGet( "Close" ) );
}
StaticVarSet( "Close", LastValue( Foreign( Name(), "C" ) ) );
Short = Cover = 0;
Buy = Cross( MACD(), Signal() );
Sell = Cross( Signal(), MACD() );
