Check out the MQL5 Reference Guide / Technical Indicators / iCustom

Thank you very much for your promptness)

On topic. I almost got it, but COUNTER does not start in the terminal log says

removed

loaded successfully

it worked!!!

you have an error here.

   v161_handle=iCustom(NULL,0,"ErolМТ5");                            
   v162_handle=iCustom(NULL,0,"ErolМТ5");
   Sum_handle=iCustom(NULL,0,"ErolМТ5");

In this case, all three variables will have the same handle. as you are calling the same indicator three times.

Yes, but as I understand it, the values of the index lines of the indicator (the values of the 3 lines)

we get through:

CopyBuffer(v161_handle,1,0,3,Spr1Buffer)
CopyBuffer(v162_handle,2,0,3,Spr2Buffer)
CopyBuffer(Sum_handle,4,0,3,SumBuffer)

here 1, 2 and 4 are the index values of the indicator lines, which are stored in the buffer,

which we then compare with each other.

But that's not a problem, it doesn't calculate correctly with these indicator line indices

[vda]

Any advice on where to go or what to do here?

void OnTick()
{  
   ArraySetAsSeries(Spr1Buffer,true);
   ArraySetAsSeries(Spr2Buffer,true);
   ArraySetAsSeries(SumBuffer,true);

   if(CopyBuffer(v161_handle,1,0,3,Spr1Buffer)<0 || CopyBuffer(v162_handle,2,0,3,Spr2Buffer)<0 || CopyBuffer(Sum_handle,4,0,3,SumBuffer)<0)
      {
      Alert("Ошибка копирования буферов индикатора номер ошибки:",GetLastError());
      }
   bool SellSpr1 =(Spr1Buffer[1] > Spr2Buffer[1]);
   bool SellSum1 =(SumBuffer[1]>=Sp);
   if(SellSpr1 && SellSum1 && !PositionSelect(_Symbol))     
      {
        PositionOpenSell1();
      }
   bool BuySpr1 =(Spr1Buffer[1] < Spr2Buffer[1]);
   bool BuySum1 =(SumBuffer[1]>=Sp);
   if(BuySpr1 && BuySum1 && !PositionSelect(_Symbol))     
      {
        PositionOpenBuy1();
      }

It is sufficient to load one copy of the indicator and address the necessary buffer indexes via the copy buffer

sergey1294:

no it is not, I cannot get the values of the 2nd line

as the values of 2 line indices stored in different buffers are compared.

   bool SellSpr1 =(Spr1Buffer[1] > Spr2Buffer[1]);

[Sergey Gritsay]

alexluek:

Wrong, it is not possible to get the values of the 2nd line

as the values of 2 line indices stored in different buffers are compared.

there may be an error in the indicator itself

sergey1294:

the indicator reads correctly

Saving the drowning is the job of the drowning.

It may come in handy for the future:

To call 2 or more indicator lines in an EA for the current bar

choose 1 handle and call the indicator, then use the copybuffer to save index values

and then work with these buffers. sergey1294 thanks for the help!
