Can a broker see your EA/indicators code & or can they manipulate it?

From what i’ve gathered, specifically from MetaTrader and no doubt a common theme with all trading software, they can indeed see what you have loaded onto it. There is a backend to all software, an entry point to a programme per se, and EA’s are stored on the trading application (otherwise when you turn your PC off what is going to happen?)

Hi @BaconSandwich,

As stated in our post above, as your MT4 broker, we cannot see the code of your EA. If you are running an EA on an MT4 terminal on your PC, and you turn off your PC, then your EA will stop running.

That’s why we have often said it’s worth considering a virtual private server (VPS) to keep your EA and MT4 terminal running 24 hours a day during the trading week, even if your own PC is turned off.
