In simple English
This tool helps you build and run automated trading systems in Python. You can write traditional rules or use artificial intelligence agents to make buying and selling decisions. It lets you test your strategy on past market data before you risk any real cash. You can then connect the same code to a live broker account to trade automatically. The software is free to download, but you will pay for market data feeds and model calls if you use artificial intelligence.
What it is
LumiBot is an open-source algorithmic trading framework with built-in support for artificial intelligence agents, historical backtesting, and twelve different brokers. It allows you to define a single strategy class and switch seamlessly between historical simulation, paper trading, and live execution.
What it is good for
Solo builders who want to test trading strategies on historical data or run automated trading bots using Python without writing custom broker connections from scratch.
