No, installing an Expert Advisor (EA) into a terminal within your VPS will not require closing open trades.
However, if you have installed EAs while you have open orders on your account, you may need to refresh the terminal for them to appear; here’s how:
- Log in to your MT4/MT5 terminal, after the EA has been installed.
- Find the Navigator window, then right-click on Expert Advisors and select Refresh.
- Now any installed EAs will appear.
You can safely follow these steps without closing any open trades within the terminal.
