anyone here running a scalable MT4/MT5 integration?
i'm building an app that needs to connect to multiple MT4/MT5 accounts and i've kind of hit the point where i need to stop guessing and pick an architecture.
my first thought was just running terminals with EAs, but the more i think about it, the more it feels like that's going to get ugly once you have more than a handful of accounts. i really don't love the idea of babysitting a bunch of windows VPSs forever. i've been looking into different options, including using a Meta Trader API instead, but it's surprisingly hard to tell what people are actually doing in production and what's just possible if you don't mind a ton of maintenance.
who've built something like this, what did you end up with? are you still running terminals behind the scenes, using an API layer, or something completely different?
trying to avoid building myself into a corner before this grows any further.
