The nautilus-indicators crate provides a comprehensive collection of technical analysis indicators for quantitative trading and market research. This includes a wide variety of indicators organized by category, with a unified trait-based architecture for consistent usage:

  • Moving averages: SMA, EMA, DEMA, HMA, WMA, VWAP, adaptive averages, and linear regression.
  • Momentum indicators: RSI, MACD, Aroon, Bollinger Bands, CCI, Stochastics, and rate of change.
  • Volatility indicators: ATR, Donchian Channels, Keltner Channels, and volatility ratios.
  • Ratio analysis: Efficiency ratios and spread analysis for relative performance.
  • Order book indicators: Book imbalance ratio for analyzing market microstructure.
  • Common indicator trait: Unified interface supporting bars, quotes, trades, and order book data.

All indicators are designed for high-performance real-time processing with bounded memory usage and efficient circular buffer implementations. The crate supports both Rust-native usage and Python integration for strategy development and backtesting.
