What it is

An open-source Python framework for algorithmic trading where the same strategy code can be used for both backtesting and live trading across stocks, options, crypto, futures, forex, and prediction markets. It supports multiple broker integrations, including Alpaca and Interactive Brokers, and provides a strategy lifecycle that separates trading logic from broker configuration, along with backtesting that produces trade logs and tearsheets without requiring an API key. Traders and developers who want to test rule-based or AI-agent strategies on historical data before deploying through a broker will find it useful. The framework requires configuring a broker account for live trading, and converting a backtest-only example into live trading involves more than flipping a setting, since run mode must be selected explicitly.
