Cannot load custom indicator (MQL5 Checker)

[Abdeljalil El Kedmiri]

Hello everyone,

Could you please help me resolve this error? The MQL5 checker displays the message: "Cannot load custom indicator...". However, both the indicator and the strategy work perfectly on demo and real accounts.

Here’s the indicator path I’m using:

#resource "\\Indicators\\Dynamic fibos.ex5"

Any advice would be greatly appreciated!

Something seems wrong in your code. Please show the part of your code where:

• You are declaring the indicator as a resource.
• You are calling the iCustom() function for it.

Also, re-read the documentation about including an indicator as a resource ... Documentation on MQL5: MQL5 programs / Resources

Working with custom indicators included as resources

One or several custom indicators may be necessary for the operation of MQL5 applications. All of them can be included into the code of an executable MQL5 program. Inclusion of indicators as resources simplifies the distribution of applications.

Below is an example of including and using SampleIndicator.ex5 custom indicator located in terminal_data_folder\MQL5\Indicators\ directory:

   handle_ind=iCustom(_Symbol,_Period,"::Indicators\\SampleIndicator.ex5");
   if(handle_ind==INVALID_HANDLE)
     {
      Print("Expert: iCustom call: Error code=",GetLastError());
      return(INIT_FAILED);
     }

   return(INIT_SUCCEEDED);
  }

From this article:
The checks a trading robot must pass before publication in the Market

If the operation of your program requires calling to the data of a custom indicator, then all the necessary indicators should be placed to the Resources. Market products are supposed to be ready to work in any unprepared environment, so they should contain all everything they need within their EX4/EX5 files. Recommended related articles:

Thank you, Fernando, for your response.

Yes, I’ve read the documentation and tried various suggestions I found in the forum. My issue is solely with the MQL5 checker.

I was wondering if there might be a way to pass the check or perhaps include the indicator in the product description as a workaround.

 #resource "\\Indicators\\Dynamic fibos.ex5"  
int Fb_handle;

int OnInit ()
:
:
//initialize crossed
   for (i = 0; i < ArraySize(crossed); i++)
      crossed[i] = true;
   Fb_handle = iCustom(NULL, PERIOD_CURRENT, "Dynamic fibos", true, Fibo_Level_1, Fibo_Level_2, Fibo_Level_3, Fibo_Level_4, Fibo_Level_5, 0.886, 0, Bars_Back, false);
   if(Fb_handle < 0)
     {
      Print("The creation of fibos has failed: Dynamic Fb_handle=", INVALID_HANDLE);
      Print("Runtime error = ", GetLastError());
      return(INIT_FAILED);
     }
   
   return(INIT_SUCCEEDED);
  }

Abdeljalil El Kedmiri #: Yes, I’ve read the documentation and tried various suggestions I found in the forum. My issue is solely with the MQL5 checker.

You may have read the documentation but you are not following it's instructions correctly.

Your code is incorrect ...

Fb_handle = iCustom(NULL, PERIOD_CURRENT, "Dynamic fibos", true, Fibo_Level_1, Fibo_Level_2, Fibo_Level_3, Fibo_Level_4, Fibo_Level_5, 0.886, 0, Bars_Back, false);

This is how you should be using the indicator name parameter ...

Fb_handle = iCustom(NULL, PERIOD_CURRENT, "::Indicators\\Dynamic fibos", true, Fibo_Level_1, Fibo_Level_2, Fibo_Level_3, Fibo_Level_4, Fibo_Level_5, 0.886, 0, Bars_Back, false);

There is no "workaround". You have to do it correctly.

"::Indicators\\Dynamic fibos"

You're absolutely right! I completely forgot to include the path. Thank you so much!
