mplfinance

What it is

A Python package providing matplotlib utilities for the visualization and visual analysis of financial data. It offers a new API that works directly with Pandas DataFrames containing OHLC data and a DatetimeIndex, automatically handling the extra matplotlib work that users previously had to do manually. Features include candlestick plotting, technical studies, subplots, price-movement plots such as Renko, coloring individual candlesticks, and realtime plot updating. The tool suits Python-based quants who want straightforward charting, though it is a visualization library rather than a trading system and leaves data sourcing and strategy logic to the user.
