Crate polars_ta 

polars-ta

Native Polars Series interface for technical analysis indicators. Numerically identical to ta-lib’s C implementation.

Quick Start

use polars::prelude::*;
use polars_ta::trend::sma_series;

let close = Series::new("close".into(), &[1.0f64, 2.0, 3.0, 4.0, 5.0]);
let result = sma_series(&close, 3).unwrap();
// result: Series of length 3 = [2.0, 3.0, 4.0]

Output Convention

Output Series are shorter than input Series by lookback elements, matching ta-lib’s C API. The caller is responsible for index alignment.

Modules

• trend — Moving averages and trend indicators
• oscillator — Momentum oscillators
• volume — Volume-based indicators
• volatility — Volatility measures

Modules

math_ops

Math operator indicators: arithmetic operations and rolling window statistics (wraps polars_ta_core::math_ops).

math_transform

Element-wise mathematical transformations (wraps polars_ta_core::math_transform). All functions have lookback = 0, so output length equals input length.

oscillator

Oscillator indicators: Polars Series wrappers.

price_transform

Price transform indicators (wraps polars_ta_core::price_transform). All functions have lookback = 0, so output length equals input length.

trend

Trend indicators: Polars Series wrappers.

volatility

Volatility indicators: Polars Series wrappers.

volume

Volume indicators: Polars Series wrappers.
