Technical analysis library implemented natively in Python?

Numerics is hard. Even if speed is of no concern to you numerical stability, error propagation, etc. are best left to dedicated, battle-probed libraries. Many of which chose not to use Python but Fortran or C as their primary language.

I don't think it's a problem if you don't understand, say, even a simple matrix-matrix multiplication in an expert library. If it says it computes A*B then it'll probably do, without you worrying how.

You probably know this but if you are going to make any substantial mathematical calculations, numpy. It is also advisable to move array data over from pandas to numpy (again, only if you have extensive math calculations) Pandas to numpy and back is easy. Also this page mostly has links to research in finance but there are many python examples scattered within: https://www.palmislandtraders.com/econ136/e136lit.htm These aren't libraries (maybe there is one or two in there somewhere) but typically github-based python programs. Good luck with your trading bot. Always a fun project! More on reddit.com

Additionally, due to the fact that this was previously the only reliable library available, it is still the most widely used library for calculating technical indicators. Having said that, installing ta-lib is difficult and requires some trial and error, making it very inconvenient to use. Unless you specifically require this library for some reason, I would choose to use its main alternative: pandas-ta.
