Autotrading is always ON in MQL5 VPS.So, if you want to stop some EA, or to change the settings of the EA, or to remove the chart, or to add the other chart with the other EA - you should do it in your Metatrader, and after that - you should synchronize it with VPS.And there is small thread - ----------------
You can pause VPS, or move your VPS subscription from one account to anotherhttps://www.mql5.com/en/forum/172120
And you can see it from VPS logs - how many charts were synchronized (were sent) with/to VPS, how many EAs (one or zero), signal subscription (yes or not): you can see it from MQL5 log from your Metatrader -
(two log VPS files) Virtual Platform Logs
After each change in your signal or EA settings/removal, you need to synchronize with your MQL5 VPS in order for them to take effect.
The other way to stop your loaded EA or signal subscription from functioning is to Stop your VPS server.
