How Can I Differentiate MT5 Account Number and MT4 Account Number ?

Users can differentiate their MT5 account(s) and MT4 account(s) based on the permutation of their account number.

The MT4 account number follows the following permutations:

MT4 Live 1 Server: 137xxxxx(7 Digits)

MT4 Live 2 Server: 40xxxx (6 Digits)

The MT5 account number follows the following permutations:

MT5 Live Server: 523xxxxx (7 Digits)

Hence, if an account number starts with 5 and has 7 digits, the account is a MT5 account number
