LumiBot vs Backtrader¶
Backtrader is one of the best-known Python backtesting libraries. LumiBot is a
Python framework for backtesting and live trading that also runs AI agents inside
the strategy. Both are open source and both use a strategy class with a
next-style loop, so moving between them is natural.

When to choose Backtrader¶
Choose Backtrader if you want a stable, self-contained backtesting library with very few dependencies and a large set of indicators, and you are happy with its current feature set. Many tutorials and books use it.
When to choose LumiBot¶
Choose LumiBot if you want active development, options and broker support beyond Interactive Brokers and Oanda, or AI agents that make decisions inside a backtest you can inspect. The same strategy class runs in a backtest, in paper trading and live.
Moving from Backtrader to LumiBot¶
There is a step-by-step guide: Migrating from Backtrader to LumiBot. In short,
Backtrader’s next() becomes LumiBot’s on_trading_iteration(), and data
feeds become a backtesting data source or a broker.
