I have studied all the docs regarding custom backtester interface. I
wrote the code but it does not do what I want. Could anyone please
look at it what the problem is. Thank you, Zozu
///////Stop Loss based on portfolio equity/////////////
StopLossEq=Optimize( "StopLossEq", 10, 1, 7, 0.5 );
SetCustomBacktestProc("");
if (Status("action") == actionPortfolio)
{
bo = GetBacktesterObject(); // Get backtester object
bo.PreProcess(); // Do pre-processing
MaxEq=bo.Equity;
for (i = 0; i < BarCount; i++) // Loop through all bars
{
if (i>0 && bo.Equity>MaxEq) MaxEq=bo.Equity;
for (sig = bo.GetFirstSignal(i); sig; sig = bo.GetNextSignal
(i))
{ // Loop through all signals at this bar
if (sig.IsEntry()) // Process entries
{
bo.EnterTrade(i, sig.Symbol, True,
sig.Price,sig.posSize); }
else
{
if (sig.IsExit()) bo.ExitTrade(i, sig.Symbol,
sig.Price); // Process exits
}
} // End of for loop over signals at this bar
bo.HandleStops(i);// Handle programmed stops at this bar
for (trade = bo.GetFirstOpenPos(); trade; trade =
bo.GetNextOpenPos())
{ // Loop through all open positions
if (bo.Equity<(1-StopLossEq/100)*MaxEq) bo.ExitTrade(i,
trade.Symbol, trade.GetPrice(i+1,"O"),5);//ExitType=ruin
} // End of for loop over trades at this bar
bo.UpdateStats(i, 1); // Update MAE/MFE stats for bar
bo.UpdateStats(i, 2); // Update stats at bar's end
} // End of for loop over bars
bo.PostProcess(); // Do post-processing
}
