Where it runs
TSCopier's standard edition is installed on Windows and adds an Expert Advisor to your MetaTrader terminals; its site says Mac users need a VPS and recommends one so copying continues when your computer is off. It sells a managed VPS from $18.99 a month on top of the licence, and a separate Cloud edition from $48.99 a month. Copygram runs in its own cloud on every plan: nothing is installed and nothing has to stay open.
