What it is

An open-source Python framework for researching, backtesting, optimizing, and live-trading crypto strategies. It offers a simple strategy syntax, a technical indicator library, support for multiple timeframes and symbols without look-ahead bias, market/limit/stop orders, partial fills, short selling, leverage, risk-management helpers, and a metrics system, plus parameter optimization via Optuna and Ray. Traders who already know Python can define and test their own strategies in minutes rather than weeks. It is focused on crypto markets, so users trading other asset classes will need to look elsewhere.
