A hundred technical indicator functions in JavaScript
ta.js is my first open-source project — around a hundred indicator functions in JavaScript, first commit 2020-08-24, v1.17.0 shipped earlier this week. I started it because I needed the indicator functions for my own work anyway and writing each of them turned out to be the cleanest way to learn them. I published it because if anyone actually used it, they might open issues on the ones I had gotten wrong, and that scrutiny loop was cheaper than anything I could have built for myself.
