TA-Lib is a C/C++ library of 200+ battle-tested technical analysis functions (indicators like ADX, MACD, RSI, Bollinger Bands, plus candlestick pattern recognition) for financial market data. ta-lib-python is the most widely used binding, built with Cython and NumPy for 2-4x faster performance than the original SWIG bindings, with Pandas and Polars support.
Use cases
- calculate RSI and MACD indicators on stock price data
- detect candlestick patterns in OHLC time series
- compute Bollinger Bands for a trading strategy backtest
- perform technical analysis on financial market data in Python
- build quantitative finance signals with 200+ indicators
- efficiently compute moving averages over large numpy arrays
When to choose
- you need industry-standard, production-proven technical analysis indicators
- you want fast NumPy/Pandas/Polars integration for large market datasets
- you need candlestick pattern recognition (CDL* functions)
- you want a stable, BSD-licensed library battle-tested since 2001
When to avoid
- you need a pure-Python solution with no C library dependency
- you want modern indicators beyond the classic 200 (consider pandas-ta)
- you need streaming/real-time tick processing (streaming API is still in development)
- you're not working with financial time-series data
