This is old code but most of it is still valid for both MQL4 and MQL5 and can be adapted to an Indicator or EA. Use it as a reference and adapt it to your own needs:

Here is a sample of my own code that I use, but it is up to you to implement properly. I'm not offering any support on it. It is up to you to do the necessary research and learning.

I need this for mt4 and mt5, i am sure that the code is different than the one that you just posted. Thanks for the help.

Did I not state that the code I provided works on both MQL4 and MQL5?

Why do you say that it is not?
Also, remember to use the strict property at the begining of the file in MQL4:
#property strict

I am pretty new to coding. I was trying to cut and paste code for putting an expiration date and/or locking the ea to a specific account #... Can anyone show me how to do that or just do it?
Here is the code that i tried. I have an mt4 and mt5 EA.. On all threads that i have read people say that it is easy... I think I must be a moron.
Can someone help.
