Hello CuriousGeo,

What you close the terminal (MetaTrader) and reopen it again you are disabling the EAs and they will stop trading.

When you use a VPS you should close the window of the VPS (usually that is a remote control window) but you should not close the MetaTrader itself. This way the EAs will not stop trading.

Why the charts disappeared….I can’t say that. But make sure not to close the MetaTrader.
