@The_Perfect_Wave yes so TD you interact with JSON in its basic form so you can send JSON messages with python to servers. Alpaca makes it easier and automatically fills in things to make it JSON format for you. Both use JSON but alpaca will be easier to use because more api features. I think that meta trader or whatever is it’s own broker platform designed for algorithmic trading using like META4 or something is the language they call it. Idk it was all proprietary using their shit so I stayed away from it. Sort of like the thinkScript in TOS. At least that’s how I understood it. Could be wrong
