iMa data in loop

New comment
 

Hello,


I have a iMa inside a loop, whitch opens symbols in the marketwatch. See below. The problem is that when there are many symbols in the marketwatch the script becomes unstable and slow. How can I fix this issue?


 for(int i=0; i< ArraySize(selectedSymbols); i++)

     {

     maHdl = iMA(selectedSymbols[i], PERIOD_D1, 64, 0, MODE_LWMA, PRICE_CLOSE);

     CopyBuffer(maHdl,0,0,7,maD1);

      IndicatorRelease(maHdl);

     Print("Getting data for: " + selectedSymbols[i]);

     }
 

  1. Please edit your (original) post and use the CODE button (Alt-S)! (For large amounts of code, attach it.)

  2.  maHdl = iMA(selectedSymbols[i], PERIOD_D1, 64, 0, MODE_LWMA, PRICE_CLOSE);
 CopyBuffer(maHdl,0,0,7,maD1);

    Perhaps you should read the manual, especially the examples.

    They all (including iCustom) return a handle (an int.) You get that in OnInit. In OnTick (after the indicator has updated its buffers,) you use the handle, shift and count to get the data.

  3. On MT5: Unless the chart is that specific pair/TF, you must synchronize the terminal Data from the Server before accessing candle/indicator values.

It is a script I use, so I don’t have oninit.

Then you must wait and verify. Your code doesn't. Re-read the links in #1.3
