If you can't see the log in the picture, here are a few of the most recent entries

Sorry, there was an error in Print() for the down arrow, the time of the up arrow was being substituted, corrected it, but it doesn't matter now.

Is the time of the rightmost candle 10:00 on the hourly chart?

Alexey Viktorov:

Is the time of the rightmost candle 10:00 on the hourly chart?

That's what I'm talking about, the Expert Advisor can't see the edge candle, and I can't get to the error, so I'm shouting for help

Here is a picture of the corrected Print() for the Down arrow

Sergey Voytsekhovsky:

Did you do ArraySetAsSeries() on both arrays ?

[Sergey Voytsekhovsky]

Artyom Trishkin:

Did you do ArraySetAsSeries() on both arrays?

Yes, to both.

int OnInit()
  {
   ArraySetAsSeries(Buf_Arrow_Buy, true);
   ArraySetAsSeries(Buf_Arrow_Sell, true);
//---
   CrossAD = iCustom(asymbol.Name(), _Period, "iCrossAD");
   if (CrossAD == INVALID_HANDLE)
   {
      Print("Не удалось создать описатель индикатора iCrossAD!");
      return(INIT_FAILED);
   }
      else Print("Хендл iCrossAD = ",CrossAD);
//---
   return(INIT_SUCCEEDED);
  }

I noticed that on theiCustom indicator activated in parallel on the chart, the arrows on the main chart do not show up. Can it be the reason?

[Artyom Trishkin]

Sergey Voytsekhovsky:

Yes, to both.

In the loop, when n==0 print the time of bar n - you will immediately understand where the loop begins.

[Sergey Voytsekhovsky]

Sergey Voytsekhovsky:

Yes, to both.

I removed and put the indicator back on, arrows appeared, EA still does not see the arrow

[Sergey Voytsekhovsky]

Sergey Voytsekhovsky:

Took it down and put the indicator back up, arrows appeared, EA still does not see the arrow at the end

I compiled the Expert Advisor - the arrows of the parallel running indicator on the main chart have disappeared. Some kind of hobgoblin has started or what?
