I think brokerages have this kind of things ? I saw ads from Revolut recently with something similar.

You are talking about 2 different things in your post though, I believe: 1 - automating long term investmenets (this is the Revolut thing) - ie, setup an amount you set for investment every month - and it automatically buys whatever you want 2 - a research tool ? (not a bot though)

Or, it just hit me while writing, are you talking about quantitatives strategies ?? If yes, then yeah, half of Wall Street was working on that ! There were some open source attempts, I think the best known was Quantopian - look it up.
