## [ta v2.0.0: three libraries on one audited spec](/blog/ta-v200-three-libraries-on-one-audited-spec) Featured

May 14, 2026

ta v2.0.0 ships ta.js, ta.py, and ta.go on the same major version, with the same indicator set audited end-to-end against textbook formulas and a comparative benchmark in each language. Pure-JS ta.js wins 66 of 67 cross-library cases at 100k bars; pure-Go ta.go wins or ties everything in its field. The Python story is more complicated, and the post is honest about why.

## [A hundred technical indicator functions in JavaScript](/blog/a-hundred-technical-indicator-functions-in-javascript)

April 26, 2026

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.
