Here is the code and the output of the Strategy Tester:  

void OnInit()
{
double K[],D[];

int s  = iStochastic(_Symbol,PERIOD_M1,5,3,3,MODE_SMA,STO_LOWHIGH);
ArraySetAsSeries(K,true);
CopyBuffer(s,0,0,15,K);
 for (int i=0; i< ArraySize(K); i++)
 {PrintFormat("K%d:  %f",i,K[i]);}


}

The output is here:

I am confused. As previously I was getting correct values but now the values are all garbage. Kindly, help me.

That's what is happening when nothing is checked.

  • Is your handle valid ?
  • Is CopyBuffer() returning an error ? How much data were copied ?

The handle is (iStochastic in OnInit), the CopyBuffer in OnTick (or OnTimer).

Please read the documentation !

Is there no way to get the values at OnInit()?
