I am trying to use single account lock from this https://www.mql5.com/en/articles/359 but even when the account number is correct it won't initialize the indicator.

Securing MQL5 code: Password Protection, Key Generators, Time-limits, Remote Licenses and Advanced EA License Key Encryption Techniques

www.mql5.com

Most developers need to have their code secured. This article will present a few different ways to protect MQL5 software. All examples in the article will refer to Expert Advisors but the same rules can be applied to Scripts and Indicators. The article starts with simple password protection and follows with key generators, licensing a given...

pkoolc1: even when the account number is correct it won't initialize the indicator.

   if (password_status == -1) Print("Indicator is not allowed to run on this account."); 
    
//---
   return(0);

Of course not. If the status is negative you print a message and return. If the status is good you return. When do you ever expect it to complete initialization?

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

Thanks, corrected my mistake. Return was in the wrong place.

Hi! I have the same problem, could you tell me where you placed the return? I am new to programming I am learning .. I appreciate your help thank you very much

Hi, Hope you have found the solution to it as you said that return was on wrong place.. Even I am having the same problem.. My indicator is not being initialized. So please can you explain what did you do with that ''return'' ?
