how to implement PivotPointUniversal in EA?

[wavetrader]

Hi, i want to create a EA which uses the pivot point universal indicator (https://www.mql5.com/en/code/102), with a strategy that buys and sells when price is near the pivot point calculated by the indicator.

 

How can i get the handle of that indicator in MQL5? Or how can i access to the price levels (pivot point, S1, R1, ...) calculated?

 

i'm sorry if it's a newbie question

 

thanks

Use iCustom() to get handle, and CopyBuffer() to get the indicator data (see example)

Thank you, that helped me a lot

When i run this code

void OnNewBar()
  {
   int hPvtInd;
   hPvtInd=iCustom(_Symbol,PERIOD_CURRENT,"pivotpointuniversal");
   if(hPvtInd==INVALID_HANDLE)
     {
      Print("Error in creating pivotpointuniversal");
     }
   double bufferP[1];
   double bufferS1[1];
   double bufferR1[1];
   
   CopyBuffer(hPvtInd,0,0,1,bufferP);
   CopyBuffer(hPvtInd,1,0,1,bufferS1);
   CopyBuffer(hPvtInd,2,0,1,bufferR1);
   
   bufferP[0]=NormalizeDouble(bufferP[0],_Digits);
   bufferS1[0]=NormalizeDouble(bufferS1[0],_Digits);
   bufferR1[0]=NormalizeDouble(bufferR1[0],_Digits);
   
   Print("pivot = ",bufferP[0]," || S1 = ",bufferS1[0]," || R1 = ",bufferR1[0]);
  }

 

 in debug mode, it works (the print function correctly shows the values of pivot, S1 and R1.

 But when i use the strategy tester, in the journal the print function prints

2012.01.16 21:10:50 Core 1 2010.11.25 20:00:00   pivot = 0.0 || S1 = 0.0 || R1 = 0.0

 

 ALL zeros as values of pivot, S1 and R1! I dont know why. PS: the function OnNewBar has been implemented with the help of https://www.mql5.com/en/articles/159

i've never came up with a solution. 

Anyway, i use this code now:

MqlRates rates[1];
double P,S1,R1,S2,R2,S3,R3;


   if(CopyRates(Symbol(),PERIOD_D1,1,1,rates)<0)
     {
      Alert("Error copying rates buffer - error: ",GetLastError());
      return;
     }
   P=(rates[0].high+rates[0].low+rates[0].close)/3;
   S1=P*2-rates[0].high;
   R1=P*2-rates[0].low;
   S2=P-rates[0].high+rates[0].low;
   R2=P+rates[0].high-rates[0].low;
   S3=rates[0].low-2*(rates[0].high-P);
   R3=rates[0].high+2*(P-rates[0].low);
   P=NormalizeDouble(P,_Digits);
   S1=NormalizeDouble(S1,_Digits);
   R1=NormalizeDouble(R1,_Digits);
   S2=NormalizeDouble(S2,_Digits);
   R2=NormalizeDouble(R2,_Digits);
   S3=NormalizeDouble(S3,_Digits);
   R3=NormalizeDouble(R3,_Digits);
   Print("P = ",P," || S1 = ",S1," || R1 = ",R1," || S2 = ",S2," || R2 = ",R2," || S3 = ",S3," || R3 = ",R3);

 it gets the daily pivot points
