4,843 backtested trading strategies. Free. Ranked by Sharpe ratio. The top one sits at 3.39. Here's what's inside: → every strategy tested over decades of real data → Sharpe ratio, t stat and years tested for each one → full Python code and data → 136 libraries for backtesting, bots, market data and broker APIs → 55 trading books, beginner to pro And here's how to turn one into a live bot with Opus 5.5: 1. Pick from the 61 strongest strategies, sorted by market: stocks, bonds, forex or crypto 2. Create a free account to unlock the Python code and data 3. Paste the code into Claude Code and ask Opus to explain every rule in plain English. When it buys. When it sells. Why. 4. Ask Opus to rerun the backtest with REAL fees on the last 3 years. If it doesn't make money after costs, stop here. 5. Have Opus convert the research code into live code that reads real prices and fires real signals 6. Connect a broker from the libraries, like Alpaca for stocks or Binance for crypto 7. Add a risk layer: fixed position size, a stop loss on every trade, a daily loss limit and a kill switch 8. Paper trade for 2 weeks with fake money. If live results don't match the backtest, the strategy isn't ready. 9. Add Telegram alerts so your phone pings on every trade. Only then go live, and start small. A great backtest is a starting point, not a promise. Most strategies die in step 4 or step 8. That's the point. Better they die there than with your money.
