Run their alerts on multiply servers? They're using some kinda bot so their posts are sent simantaneously to all discords they're in. Do they build their own or is there somewhere you can download it for free or purchase?
It's easy to write using python. The API is well documented. It might become more difficult to get the information into python. What would you like to distribute? Manually written messages or real time trading events? I use discord to notify myself about runtime errors of my trading algos.
Example of one of the analysts on a discord I am in. He's on multiply trading servers throwing out his alerts.
