0DTE Options AI Trading Bot

This bot trades 0DTE options: options that expire the same day. It sells a bear call spread on SPY, the S&P 500 ETF, and keeps the premium if SPY stays below the short strike by the close. 0DTE is now the biggest part of the index options market: in August 2025 it was a record 62.4% of all SPX options trading (Cboe).

How it works

1. Research agent checks SPY and the calls that expire today every 15 minutes. It finds the call near 0.20 delta and the call 5 points higher, with their prices.

2. Trading agent sells that spread once a day, risking about 1% of the account.

3. The trading agent keeps watching and closes the spread early when you have kept half the credit, when closing costs twice the credit, or when SPY rises above the short strike. It never opens a new spread in the last 30 minutes of the day.

Change symbol to "SPX" to trade S&P 500 index options, if your broker offers them.

Backtest tear sheet

GPT-6 Luna, January 5 to 6, 2026, Alpaca option prices, $100,000 start. Each morning the bot sold a 2-contract SPY bear call spread that expired that day, for about $0.27 a share. Both days SPY rallied into the short strike, and the bot closed the spread early at its loss limit, near 2 to 3 times the credit because it checks every 15 minutes. It ended at $99,826 (-0.2%). A losing window, shown as it happened.

Run it yourself

pip install lumibot
python -m lumibot.example_strategies.ai_0dte_options_trading_bot

Put these in your .env file: OPENAI_API_KEY, and your broker keys (for example ALPACA_API_KEY, ALPACA_API_SECRET, and ALPACA_IS_PAPER=true for paper trading). With IS_BACKTESTING=false the bot trades. With IS_BACKTESTING=true it backtests instead; set BACKTESTING_START and BACKTESTING_END to pick the dates, and start with a week or two, because every AI call costs a little. Option and minute-bar backtests use Alpaca’s free history, so paper Alpaca keys are enough.

Good to know

• 0DTE options move very fast. Paper trade first.

• The bot checks every 15 minutes, so it makes a lot of AI calls per day.
