What it is

An open-source quantitative trading framework written in C++ with Python bindings, focused on fast research and backtesting workflows. It decomposes strategies into independently replaceable parts such as signals, stop-loss/take-profit rules, money management, slippage and fund allocation, which users can combine into a reusable strategy library and validate through backtests. It supports multiple storage backends (HDF5, MySQL, ClickHouse, SQLite) and suits quantitative researchers who want to assemble and test systematic strategies from modular components. As a research tool, it provides no securities trading service itself, and users bear full responsibility for any trading interfaces they add, with the project intended for study and academic use only.
