1//! # polars-ta-classic
2//!
3//! A 1-to-1 Rust/Polars reimplementation of
4//! [pandas-ta-classic](https://github.com/xgboosted/pandas-ta-classic).
5//!
6//! Provides 150 technical-analysis indicators across 9 categories:
7//! momentum (45), overlap (36), trend (18), volume (17), volatility (14),
8//! statistics (10), candles (5), performance (3), cycles (2).

10// TA indicators inherently take many parameters and rely on indexed
11// access to prior bars; both patterns are intrinsic to the algorithms.
