>>11893621I think of it because I played with it two years ago.
Take any active trading platform, put 100$ there, figure out the Python API (currency of choice => price, buy-order, sell-order) and query the price once a minute. You get a stream of prices and the algorithm when to buy and when to sell is really up to you.
The most naive way to make money is to do this on two exchanges and buy+sell whenever the price difference on the two is larger than the trading fee the exchange charges. Obviously, you need two exchanges with lots of volume and obviously, don't expect to make any money because if you find this situation, clearly other people are already doing it.
I ended up never making a nice summary about my hacky bot, but you'll definitely find youtubers or tutorials about it.
For something arguably related, I'm currently thinking if I should try to write a chess-bot from scratch and use
lichess.org as interface. I had some fun with the NIST dataset and a rough idea of how chess programming works and I'd like to combine the two. I do C++ and Python at work too, and I even know rudimentary Haskell - although I'd say Python is the obvious choice for quickly doing the website interaction. If you're interested in something like that (or somebody else, for that matter), you can find my contacts somewhere on the user page here
