I have been able to add custom metrics to the Optimization Reports, but for some reason can't add a column to the Trade List Backtest report. Hoping someone might be able to chime in here, as the custom backtester confuses me.
What I want to do is fairly simple. In my actual trading system, I cycle through hundreds of possible conditions per bar. If any one condition is true, then I Buy. I want to add a custom metric to the backtest report that lists which condition generated the Buy signal.
For the sake of debugging, below is a very simplified AFL (not my actual system). I simply want to feedback the condition number into the backtester. But it does not work. If I add an optimize statement at the top, it will add the custom metric to the Optimization report. But even then that column does not reflect correct values.
So how do I add the column to the Backtest report? I would have thought the below code would do the trick. And how do I feedback the correct values? Perhaps I need to FPUT each condition, during the loop, to an external file, then FGET the file for every trade in the backtester? That might work, but feels inefficient:
//------------------------------------------------------------------------
// SIMPLE TRADING SYSTEM BASED ON VARIOUS CONDITIONS
//------------------------------------------------------------------------
FastMA = MA( C, 10 );
SlowMA = MA( C, 20 );
Condition1 = Cross(FastMA, SlowMA);
Condition2 = Cross(SlowMA, FastMA);
Condition3 = Cross(C, SlowMA);
Condition4 = Cross(SlowMA, C );
for(a = 1; a < 5; a++)
{
Condition = VarGet( "Condition" + NumToStr( a, 1.0, 0 ) );
Buy = Condition;
Sell = BarsSince(Buy) > 12;
}
//---------------------------------------------------------------------------
// WANT TO ADD THE CUSTOM COLUMN, "CONDITION" TO BACKTEST REPORT
//---------------------------------------------------------------------------
SetCustomBacktestProc( "" );
if ( Status( "action" ) == actionPortfolio )
{
bo = GetBacktesterObject();
bo.Backtest( 1 ); // Call Backtest but set NoTradeLists to true
bo.AddCustomMetric( "Condition", a, 0,0,0 ); // Add the custom metric
bo.ListTrades(); // Now generate the backtest report with custom metric
}
