I think I made it (is this right?):
SetOption("UseCustomBacktestProc", True );
SetCustomBacktestProc("",True);
if( Status("action") == actionPortfolio ) // point to correct iteration of backtest engine
{
//initialize custom backtest engine
//bo is backtestobject
bo = GetBacktesterObject();
bo.Backtest(); // run default backtest procedure
st = bo.GetPerformanceStats(0); // get stats for all trades
totalLossTrades = totalWinTrades = totalRuns = 0;
for (trade = bo.GetFirstTrade(); trade; trade = bo.GetNextTrade())
{ // Loop through all closed trades
if (trade.GetProfit() > 0) // If this was a winning trade
{
if (totalWinTrades == 0) totalRuns++;
totalWinTrades++;
totalLossTrades = 0;
}
if (trade.GetProfit() < 0) // If this was a winning trade
{
if (totalLossTrades == 0) totalRuns++;
totalLossTrades++;
totalWinTrades = 0;
}
} // End of for loop over all trades
N = st.GetValue("AllQty");
R = totalRuns;
WIN = st.GetValue("WinnersQty");
LOSS = st.GetValue("LosersQty");
X = 2 * WIN * LOSS;
Z_Score = (N*(R-0.5)-X)/SQRT((X*(X-N))/(N-1));
bo.AddCustomMetric( "Z-Score",Z_Score );
bo.AddCustomMetric( "totalRuns",totalRuns );
}
