Array of arrays: invalid array access

[Roberto Gentili]

I would like to use an array of arrays as in the following code

double data[2][1];
int indicatorIndex;

int OnInit() {
   int index = indicatorIndex++;
   SetIndexBuffer(index,data[0],INDICATOR_DATA);
   index = indicatorIndex++;
   SetIndexBuffer(index, data[1],INDICATOR_DATA);
}

... But I get the error "invalid array access": how can I fix it?

Indicator buffers are dynamic arrays managed by terminal. You should not use statically allocated ones on your own.

If you want to use an array of arrays as index buffers in an indicator, you may use IndBufArray.mqh from the algotrading book (look into the section describing "IndUnityPercent" indicator).

SetIndexBuffer is not used that way, and doesn't support two-dimensional arrays

these kind of arrays are used to store values in rows and columns

double data[2][2];

int OnInit()
  {
//---
   data[0][0] = 1.1;
   data[0][1] = 1.2;
   
   data[1][0] = 2.1;
   data[1][1] = 2.2;   
   
   
   Print("This array value: ",  data[1][0]);
//---
   return(INIT_SUCCEEDED);
  }
