lumibot 4.5.19

Python framework for algorithmic trading: backtesting and live deployment for stocks, options, crypto, futures, and forex. Same code for backtest and live trading.

Lumibot: Backtestable AI Trading Agents for Algorithmic Trading

Build deterministic trading strategies, multi-agent LLM trading systems, and hybrid strategies that backtest, paper trade, and execute through real brokers. Lumibot is an open-source algorithmic trading framework for stocks, options, crypto, futures, forex, indexes, SEC fundamentals, macro data, technical indicators, and AI agents that can actually place orders.

Build, backtest, and deploy an AI trading bot on BotSpot
Describe a strategy in plain English. BotSpot generates Lumibot code, runs the backtest, and deploys it in the cloud.

What You Can Build

• Deterministic strategies: normal Python logic, indicators, if statements, scheduled rules, position sizing, and risk controls.
• AI-agent strategies: one or more agents that reason through evidence, call tools, write memory, and optionally place orders.
• Backtests: replay historical data and simulated orders with artifacts you can inspect.
• Paper or live trading: reuse the same strategy code with real broker state and real order routing.

Backtestable AI Trading Agents

Lumibot now includes a built-in AI agent runtime for financial research, reasoning, debate, risk review, and trade execution. Agents can inspect market data, read filings, query indicators, search memory, compare macro context, and submit orders through the same Lumibot strategy loop used by normal backtests and live trading.

Classic Python strategies are still first-class. The point is not to replace deterministic trading logic. The point is that Lumibot lets you choose the right level of intelligence: fixed rules, AI agents, or a hybrid where Python handles the hard gates and agents reason through evidence.

An investment committee is one example pattern:

In that pattern, read-only research agents gather evidence and a trading-enabled portfolio manager decides whether to place Lumibot orders. It is one pattern, not the only pattern. You can build a single-agent strategy, a specialist research flow, bull/bear/neutral committees, model-vs-model debates, deterministic execution gates, or agent reviewers layered on top of normal Python logic.

Built-in AI agent tools include market/account state, order inspection, DuckDB queries, documentation search, Alpaca news when credentials exist, technical indicators, SEC fundamentals and filings, FRED macro data, local memory, and Telegram notifications.

Build Without Code on BotSpot

BotSpot is the managed cloud product built on Lumibot. Use it when you want to describe a strategy in plain English, have AI generate Lumibot code, backtest it, and deploy it without managing servers.

• Build strategies using natural language -- the AI writes production-ready Lumibot code for you
• Backtest against years of historical data with a single click
• Deploy to live trading with real brokers including Alpaca, Interactive Brokers, Tradier, Schwab, Tradovate, TopstepX via ProjectX, Bitunix, Coinbase, Kraken, WEEX, KuCoin, Binance, BitMEX, Bybit, and OKX
• Browse a marketplace of proven, community-built strategies you can run immediately

Start on BotSpot: Build, backtest, and deploy AI trading bots

Quick Start

pip install lumibot

from datetime import datetime
from lumibot.strategies import Strategy
from lumibot.backtesting import YahooDataBacktesting

class MyStrategy(Strategy):
    def on_trading_iteration(self):
        if self.first_iteration:
            aapl = self.create_order("AAPL", 10, "buy")
            self.submit_order(aapl)

MyStrategy.backtest(
    YahooDataBacktesting,
    datetime(2023, 1, 1),
    datetime(2024, 1, 1),
)

python my_strategy.py

That same strategy code works with live brokers. Just swap the broker class.

For full setup guides, broker tutorials, AI-agent docs, examples, and deployment notes, use the Lumibot documentation.

Deploy Live

Option A: BotSpot (managed cloud)

BotSpot runs your Lumibot strategies on hosted infrastructure with scheduling, monitoring, and live execution. Build strategies with AI, no coding required.

• Create trading bots using natural language
• Backtest with historical data
• Deploy to trade automatically 24/7
• Join a community of algorithmic traders

Open BotSpot.trade

Option B: Self-hosted (full control)

Run Lumibot on your own machine with any supported broker:

from lumibot.brokers import Alpaca
from lumibot.traders import Trader

ALPACA_CONFIG = {
    "API_KEY": "your-key",
    "API_SECRET": "your-secret",
    "PAPER": True,
}

broker = Alpaca(ALPACA_CONFIG)
strategy = MyStrategy(broker=broker)

trader = Trader()
trader.add_strategy(strategy)
trader.run_all()

Supported Brokers

Lumibot supports stocks, options, crypto, futures, forex, and indexes across several broker integrations:

• Alpaca
• Interactive Brokers and Interactive Brokers REST
• Tradier
• Schwab
• Tradovate
• TopstepX futures (via ProjectX)
• Bitunix
• Selected CCXT crypto paths. Coinbase, Kraken, and WEEX have auto-detected credential paths; KuCoin, Binance, and BitMEX have documented manual CCXT setup paths; Kraken, Binance, KuCoin, BitMEX, Bybit, and OKX have documented backtesting examples. Lumibot does not claim blanket support for every CCXT exchange.

Recommended Data Provider

For the deepest historical coverage (stocks, options, futures, indexes), we recommend ThetaData. Use promo code BotSpot10 for 10% off your first order.

AI Trading Agents

Lumibot includes a built-in AI trading agent runtime. Build agents that run identically in backtests and live trading.

• Create agents with self.agents.create(...)
• Use a different model per agent with model="openai/gpt-5.5" or any LiteLLM/ADK-supported provider string
• Make research agents read-only with allow_trading=False
• Give agents built-in SEC fundamentals, filings, FRED macro data, indicators, memory, and notifications
• Use DuckDB for time-series analysis instead of dumping raw bars into prompts
• Mount external MCP servers for news, macro data, filings, or any domain-specific tools
• Replay identical agent decisions in backtests without paying for another model call

• Agent Documentation
• Agent Flow Design
• AI Investment Committee Example
• Standalone AI Committee Demo
• Stock Agent Example
• Options Agent Example
• Full Guide

Memory and Traceability

AI strategies can record decisions, lessons, open theses, tool calls, and run artifacts as local files. This makes an AI backtest reviewable instead of a black box: you can inspect why the agent traded, which tools it used, and what it remembered for later iterations.
