Test AI trading ideas on paper first

“I want AI to help with trading ideas without risking real money.”

Use AI to research, write down rules and test them on past data or a paper account. Never let an agent trade real money on its own. Not financial advice.

Fix it yourself in 3 steps

Write your idea as clear rules: what triggers a buy, a sell, and how much.
Ask the AI to backtest the rules on past data and log every simulated trade.
Paper-trade for a few months and compare to simply holding an index fund.

Copy this prompt

Turn this idea into exact trading rules: [idea]. Backtest it on [ticker/period] data, log every simulated trade, and report total return, worst drawdown, and comparison to buy-and-hold. List ways the test could be misleading. Paper trading only — don't connect to any brokerage or place orders. Not financial advice. Stop after the report.

Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
