Why, if (indicator) is written to draw only on the first run

   if(_LastError==0 && prev_calculated==0)
     {
      for(i=countBars-1;i>0;i--)
        {
         Label1Buffer[i]=(p_Symbol[i]+pGBP_Symbol[i])/2;
         Print("Label1Buffer "+IntegerToString(i)+" : "+DoubleToString(Label1Buffer[i]));
        };
     };

with a new tick the buffer is reset (the line disappears)? The buffer does not remember the old values. How to properly make it draw everything on the first run and only the difference if rates_total-prev_calculated>0?

upd man... it's because of moving ArrayInitialize to OnCalculate... Either rubbish on the first run, or a hassle.

For now, the issue has been resolved.

I meant to build it myself using MQL5 tools.

Build whatever you want in the indicator window.

Maybe you can tell me how, where to start?

Can you be more specific? How to transfer in a buffer a value of some parameter of tool RTS-9.13 from a window of the market review, for example volume of orders on sale?

If you don't want to understand it yourself, you can go to Work. It will cost you 50 quid and you won't have to think about it. There are classes and standard functions for orders, positions, trades and they are easy to find by entering this into the search. How buffers are filled in the link I gave.

Thank you. I'll look it up.

How to pass a receiving array name in Copy*?

There are double a[], b[], c[], and string name={"a", "b", "c"};

I need

for(i=0;i<2;i++)
     {
       CopyClose(name[i],_Period,0,countBars,Array);
     }

How can I copy the array name instead of Array?

Something simple, can't find it.

There is a "standard deviation channel" object. How can I programmatically obtain the distance in pips from the centre line to the edge of the channel?
