Stop recomputing OHLCV indicators after every new bar

volas is a Rust-backed Python library for efficient OHLCV data processing. It allows for cheap indicator refreshes and can handle large datasets. It provides a pandas-shaped API and supports various indicators and output formats. If you work with live OHLCV pipelines, you can provide feedback on its directive API, missing indicators, and performance comparison. You can find it on GitHub.
