Protecting EA from unauthorized use

[nidalzd]

I developed and EA and wanted to protect it from unauthorized use , so i used time limit from an article mentioned here.

#property copyright "Copyright © 2009, etc"
#property link      "http://etc.com.ua"

int start()
{datetime LastAllowedDate = D'2009.09.11 23:59:00'; 

  if (TimeCurrent() >= LastAllowedDate) 
  {
    Print("Demo period has expired " + TimeToStr(LastAllowedDate,TIME_DATE|TIME_SECONDS));
    return(1);
  }
  
  Print("You can work until "+ TimeToStr(LastAllowedDate,TIME_DATE|TIME_SECONDS));
}

and the ea is still working normally although it is expired

How would that stop the EA though, shouldn't it be in the OnTick() event?

#property strict

datetime LastAllowedDate = D'2009.09.11 23:59:00'; 

void OnTick() {
   if( TimeCurrent() <= LastAllowedDate ) {
      Print( "You can work until ",      TimeToString( LastAllowedDate ) );
    } else {
      Print( "Demo period has expired ", TimeToString( LastAllowedDate ) );
      ExpertRemove();
    };
};
