EA Indicator: Signal shift

I want to shift the signal arrow to the previous candles. See below. This is a signal indicator, not EA.

 

Is there somewhere in this code I can shift the arrow?

double getDrawOffset(int signalIndex, int i) {
   if(signalIndex == 1) {
      if(Signal1Pos == "High") {
         return(High[i]+atrOffset + (sigCountOffsets(signalIndex, "High"))*(atrOffset*0.1));
      } else {
         return(Low[i]-atrOffset - (sigCountOffsets(signalIndex, "Low"))*(atrOffset*0.1));
      }
   }
   if(signalIndex == 2) {
      if(Signal2Pos == "High") {
         return(High[i]+atrOffset + (sigCountOffsets(signalIndex, "High"))*(atrOffset*0.1));
      } else {
         return(Low[i]-atrOffset - (sigCountOffsets(signalIndex, "Low"))*(atrOffset*0.1));
      }
   }

   return(false);
}

Possibly add an extern shift.

 

Hello,

 

you should be able to achieve this by a small change in the code. Find a function drawSignal and add one line in the beginning:

 

void drawSignal(int signalIndex, int i, double value) {

    i = i-1;

    … rest of the code unchanged

Awesome, thanks man. Your  software and EAs teaching me a lot about mql4
