How to lock the indicaotr with password

[Cromo]

I have just protect the indicator with password key.

extern string Password = "The password";

void OnTick()
{
    if( Password != "The password" )
    {
        Comment("The password is wrong.");
        return;
    }
 
  ///Main code/////  


}

But if I use this code, I can not read indicator buffer signal. It is always empty value.

Can you tell me why this happened?

Use the debugger or print out your variables, and find out why. Do you really expect us to debug your code for you?
