This package should be a swiss knife for building automated trading bots in Common Lisp. At present, it is draws all of its information from publically accessilble sources, namely the still extant but existentially tenuous yahoo finance, the free (but requiring registration) API offered by finnhub.io, and most recently, the alpaca trading API. Alpaca doesn’t really offer service to people outside the United States, which is a pain in the ass, because their service is well documented, and their APIs are solid. Ultimately, I’m probably going to use this collection with Interactive Brokers, which operate all over the world, but specifically in Canada where I am located.
I will be adding support for various API’s as I move along scratching my own itches. I’d like to get the yahoo finance support to parity with the yfinance python module built to their API.
