what should be the name of the custom indicator in IndicatorCreate() function as first parameter if we import indicator in ExperAdvisor as resourse?

[HF2020]

Hi and good day all
I really appreciated your help if let me know how to define the name of imported indicator as resource to the ExperAdvisor in  IndicatorCreate() function.
As you know probably we have to pass the name of custom indicator as first parameter.
The case when a custom indicator handle is created in OnInit() function. FYI I have read this page but I could not find my answer.

#resource "\\Indicators\\Indicator.ex5"

// ============================
MqlParam Indicator_Params[];
      ArrayResize(QQE_Params_4T,8);
      Indicator_Params.type         =TYPE_STRING;
      Indicator_Params.string_value=Name_of_Indicator;  ===> ???? (how to define it since its custom indicator 

// ============================
int  IndicatorCreate(
   string           symbol,                            // symbol name
   ENUM_TIMEFRAMES  period,                            // timeframe
   ENUM_INDICATOR   indicator_type,                    // indicator type from the enumeration ENUM_INDICATOR
   int              parameters_cnt=0,                  // number of parameters
   const MqlParam&  parameters_array[]=NULL,           // array of parameters
   );

Thanks in advance

Thanks for sharing this dear William but I am using the CiCustom class which using the create function inside the create function as you can see the IndicatorCreate function has been called by passing the params which should be the include name of the indicator
how to define the name, btw I have tried what you have suggested ( ::Indicators\\indicator.ex5 ) as name of indicator but still it could not find it and load the indicator.
let say you have indicator and you imported as follow

#resource "\\Indicators\\name_custom_indicator.ex5"

then how would you name it if you are going to pass it as param to create function of CiCustom class,

MqlParam Indicator_Params[];
      ArrayResize(QQE_Params_4T,8);
      Indicator_Params.type         =TYPE_STRING;
      Indicator_Params.string_value="::Indicators\\name_custom_indicator.ex5";  ===> ???? you will define it like this, not worked for me.

 create function of CiCustom class

//+------------------------------------------------------------------+
//| Creation of the indicator with universal parameters              |
//+------------------------------------------------------------------+
bool CIndicator::Create(const string symbol,const ENUM_TIMEFRAMES period,
                        const ENUM_INDICATOR type,const int num_params,const MqlParam &params[])
  {
//--- check history
   if(!SetSymbolPeriod(symbol,period))
      return(false);
//--- create
   m_handle=IndicatorCreate(symbol,period,type,num_params,params);
//--- check result
   if(m_handle==INVALID_HANDLE)
      return(false);
//--- idicator successfully created
   if(!Initialize(symbol,period,num_params,params))
     {
      //--- initialization failed
      IndicatorRelease(m_handle);
      m_handle=INVALID_HANDLE;
      return(false);
     }
//--- ok
   return(true);
  }

Thanks

Read the documentation about resource it's right there with code example.

Thanks dear Alian
if you are referring to this page and GetRelativeProgramPath();
I have used this but for your information it will return the directory of ExperAdvisor and name of it.
lets say I have multiple indicator as resource how can I distinguish this.

  string path=GetRelativeProgramPath();
//--- indicator buffers mapping
   handle=iCustom(_Symbol,_Period,path,0,0);
   if(handle==INVALID_HANDLE)
     {

based on the above code I have to define my Indicator params which include the name as below but it is not working

MqlParam Indicator_Params[];
      ArrayResize(QQE_Params_4T,8);
      Indicator_Params.type         =TYPE_STRING;
      Indicator_Params.string_value= GetRelativeProgramPath();  ===> ???? will you define it like??? 

it has not worked for me
Please let me know what should I define in Indicator_Params.string_value= ??????
Thanks in advance

???? will you define it like??? 

Of course not. I have no idea what you are trying to do. Post all the needed code that COMPILES, if you need coding help. Your snippets are useless.

Ok sure this my EA code
I have QQE indicator which I have imported as resource and I want to create handle of this indicator and use it in my code later.
this is error I received whenever I run my EA.

I hope it is clear now what I am trying to do
I just need to know what should I define the name of the custom indicator as param

   string path=GetRelativeProgramPath();

   ArrayResize(QQE_Params,8);
   QQE_Params[0].type         =TYPE_STRING;
   QQE_Params[0].string_value=path;  =======> this path is NOT correct 

Thanks

Dear @Alain Verleyen did you get the idea what I am trying the do
I need to know how to define the name (or maybe the path) of the custom indicator which imported as resources into the EA.
Really Appreciated your help.

You should not try all and anything without understanding what you are doing.

   QQE_Params[0].string_value = "::Indicators\\Z_QQE.ex5";
