Crate quantwave_polars 

quantwave-polars

Polars integration for QuantWave: the QuantWaveExt::ta() namespace on LazyFrame for 218 vectorized indicators, plus bt for backtest helpers.

Quick start

use polars::prelude::*;
use quantwave_polars::QuantWaveExt;

df.ta().rsi("close", 14)

Under the hood, expression plugins call the same quantwave-core math as streaming Next<T> structs — see parity guide.
