Abort EA during OnInit()

Route206 2015.06.16 14:12

Apologies for what could potentially be a stupid question, but i just don't seem to be able to figure it out: Can someone help me in terminating an EA when during OnInit() it find certain parameters, values etc unacceptable?

something like the below:

OnInit()
   {   
   if(certain_variable == acceptable)
      {continue;}
      else
      {Alert("Unacceptable input for ",certain_variable," pls check and start over");
      SOMETHING_THAT_TERMINTES_THIS_EA();}
   return;
   }

I can put in all the Alerts i want, but the things starts and then crashes when indeed inputs are off.

thank,

Ron.

OnInit()
   {   
   if(certain_variable == acceptable)
      {continue;} << can't use continue outside of a loop.
      else
      {Alert("Unacceptable input for ",certain_variable," pls check and start over");
      SOMETHING_THAT_TERMINTES_THIS_EA();}
   return;
   }

Event Handling Functions - MQL4 Documentation

int OnInit()
   {   
   if(certain_variable != acceptable)
      {Alert("Unacceptable input for ",certain_variable," pls check and start over");
      return INIT_PARAMETERS_INCORRECT;}
   return INIT_SUCCEEDED;
   }
