mktlib 0.9.0

Polars-native financial market toolkit

mktlib

Financial market toolkit built entirely on Polars.

tl;dr

• Fast enough for real work — vectorized Polars engine grid-searches thousands of parameter combos on minute-bar data without reaching for Numba or Cython
• Lightweight — pure Polars throughout, including synthetic data generation via Rust-native plugins. No pandas, no NumPy, no heavy ML stack
• Well tested — cross-validated exchange calendars, full backtest parity tests across engines, and pandera schema validation on every DataFrame-returning function to guarantee no silent column/dtype regressions
• Swiss-army knife — scheduling, rates, metrics, backtesting, reporting, and data generation in one package. Great for learning, prototyping, or production
• Apache 2.0 — use it anywhere, fork it, vendor it, no strings attached

Disclaimer: Backtesting results and any computed market returns are for educational and research purposes only. They do not constitute financial advice, and past performance does not indicate future results.
