Is the CTrailingPSAR class tied to using the signal files from Expert\Signal?

[Conor Mcnamara]

If you would make an EA with the EA wizard, and chose parabolic sar for the trailing stop loss, it adds something like this code with nothing in OnTick:

#include <Expert\Trailing\TrailingParabolicSAR.mqh>

// global variables
input double Trailing_ParabolicSAR_Step =0.1;         // Speed increment
input double Trailing_ParabolicSAR_Maximum = 0.2;         // Maximum rate

OnInit()
{
        CTrailingPSAR *trailing=new CTrailingPSAR;
        trailing.Step(Trailing_ParabolicSAR_Step);
        trailing.Maximum(Trailing_ParabolicSAR_Maximum);
}

the trailing stop based on parabolic SAR works along with other signals that you add to the wizard, but I could not get the psar trailing stop to work in a custom EA using the MqlTradeRequest and MqlTradeResult classes, I'm just wondering if anyone knows
