Build a strategy backtesting engine with Claude Code
Describe entry, exit, stop and size in plain English; include fees and slippage; get win rate, max drawdown and a dashboard.
Prompt for your agent
Goal: Test a trading strategy on historical data before risking money. Setup: agents used in source: Claude; tools/MCPs stated: TradingView. Steps: 1. Open Claude Code and send the backtesting prompt (attached to the post). 2. Describe your strategy in plain English: entry, exit, stop, position size. 3. Tell it to include fees and slippage. 4. Run it and ask for win rate, max drawdown and average R per trade. 5. Ask for a dashboard to visualise the results. 6. Quality-check: import the source into TradingView and compare. Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify. Note: The author’s claimed returns are his own; past performance isn’t a forecast. Based on: Miles Deutscher — https://x.com/milesdeutscher/status/2108079450927833334
