Specification
We have an existing Expert Advisor (EA) for MetaTrader 4.
We need to restrict the EA so it only works on specific MetaTrader account ID(s).
Key Requirements:
Add account ID locking functionality to the EA.
EA should run only on authorized account number(s).
If used on any unauthorized account, the EA should:
Stop trading, and/or
Display an error message (e.g., “Unauthorized Account”).
Ability to easily update or add allowed account IDs (preferably via input or internal list).
Ensure the lock cannot be easily bypassed.
Maintain all existing EA functionality without changes.
