My EA should run for specified currency! need support?

[Sherif Hasan]

I would like to run EA for specified currency:

For dingle currency i have used following code:

if (Symbol() == "USDJPY")
{
return(0);

}

Question:

If i want to specify multiple currency shall i use following code?

if (Symbol() == "USDJPY || AUDJPY || NZDJPY")

If its wrong please give me an exact logic to use.

This is a right variant: if ( Symbol() == "USDJPY" || Symbol() == "AUDJPY" || Symbol() == "NZDJPY" )

Sign " || " is word "or" in English

Sing " && " is word "and" in English

1. Play video	Please edit your post. For large amounts of code, attach it.

2. You wrote

   if (Symbol() == "USDJPY || AUDJPY || NZDJPY") // no such pair "USDJPY || AUDJPY || NZDJPY"
   

   Even if you wrote

   if (Symbol() == "USDJPY" || "AUDJPY" || "NZDJPY") // if( boolean or string or string ) is nonsense
   

   You need to write if (boolean1 or boolean2 or boolean3):

    if ( Symbol() == "USDJPY" || Symbol() == "AUDJPY" || Symbol() == "NZDJPY" )

3. if (Symbol() == "USDJPY")
   {
   return(0);
   
   }

   This rejects USDJPY and accepts all others. If you only want those three you'll have to reverse the test

   if ( Symbol() != "USDJPY" && Symbol() != "AUDJPY" && Symbol() != "NZDJPY" ) 
   {
      return(0); // reject symbol
   }
   // symbol is ok
