How to edit the name of the indicator (.mq.4) ? and to put a cord that only i can allow anyone to use this indicator by putting his LOG IN id .

int OnInit()
  {
   IndicatorShortName("NONAME");
   return(INIT_SUCCEEDED);
  }

 Lots of different ways. Here is one example:

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {
   if(!ValidAcc()) { return(rates_total); }
   
   // rest of your code

   return(rates_total);
  }

bool ValidAcc()
  {
   switch(AccountNumber())
     {
      case 12345: return(true);
      case 78910: return(true);
      // add more account numbers here
     }   
   return(false);
  }

thanks dear but its not compiled error. please send me mail on ankitkumarsjs@gmail.com 

or comment your mail so that i can contact you. please setup it 

The code compiles without error at my end:

I'm afraid I don't offer support by email, but if you post up your code here (using SRC) the community should be able to help

i am getting this error can you say where to insert the code you gave ?

That error tells you that your indicator already has OnCalculate. There can only be one in an indicator.

If you are using the standard MACD indicator, it would look like this (new code highlighted in yellow):

AM UNABLE TO TO IN THIS PLEASE DO IN THIS AS I DID IN MACD 

THANKS
