How to NOT to run EA on certain symbol.

New comment
 

Dear all.

How do I code if I don't want to make EA run on certain symbol?

I took the code from other topic.

Thanks in advanced.


int OnInit()

{
   // Check Licensing Restrictions
   if( boolRestrictOnInit() ) return( INIT_FAILED );

   // ...

   return( INIT_SUCCEEDED );  // Initialisation complete
}

void OnDeinit(const int reason){
ObjectDelete(NULL,"close_all");
   }

void OnTimer(){
   onTimer();
   }

void OnTick()
{

   if(IsTesting())
      
      (onTimer()) return;
      
   // Check Licensing Restrictions
   if( boolRestrictOnTick() ) return;
   
   /// ..
}

               { return( boolRestrictAlert() ); }

            boolRestrictionsUnverified = false;
         }
      }
   }
   return( false );

Figure it  out!

 
Do not post code that will not even compile. 
   boolRestrictions =
      boolRestrictAccountNumber  ||
      boolRestrictSymbols
The latter is a function.
 

Before opening an order just write this:

if(_Symbol != "EURUSD")

And this "if" makes sure that the symbol isn't  EURUSD

 
what is this function for though? you can simply choose not to run the EA in that particular chart?
 
Thanks to all
 
You may also want to une the StringSubstr() Function to Filter out broker added Letters to different Pairs/Symbols. (Ex: EURUSDecn could be reduced to EURUSD)
