Yes, it’s possible for two people to log into the same MetaTrader 4 account at the same time from different devices, including mobile phones. MT4 allows multiple simultaneous sessions using the same login credentials. However, you should be careful: any trades, changes, or closures made by one person will immediately affect the account and be visible to the other. This can easily lead to confusion or conflicting actions. It’s important to communicate clearly with your partner and agree on rules for trading, or consider using separate accounts with an investor or manager password if you want clearer control and monitoring.
