You don't want to keep Windows and MetaTrader running
TSCopier's standard edition is installed on Windows and places MetaTrader trades through an Expert Advisor, so it copies only while that computer is on. Its site says Mac users need a VPS; its managed VPS costs from $18.99 a month on top of the licence, and its Cloud edition starts at $48.99 a month. Copygram runs in its own cloud on every plan, with nothing to install. TelegramFX Copier is cloud-based too, and needs a MetaAPI subscription.
