Hello, you can use the STP standard account of Live 1, Live 5 and Live 6 servers, the ECN professional account of Live 4 and Live 5 servers, and the CENT account of Live 3 and Live 5 servers to create a signal source or copy account.
However, please note that the account types of the signal source and the follower must be consistent. STP standard accounts can only follow STP standard accounts, ECN professional accounts can only follow ECN professional accounts, and CENT accounts can only follow CENT accounts.
