Sonnet 5 + Claude Code strategy makes 369%

Anthropic just released Claude Sonnet 5 — so I put it to work doing real algo trading research to see how it stacks up against Claude Opus 4.8 and Sonnet 4.6. Using the Jesse framework and its MCP tools, I had it write, backtest, optimize, and Monte-Carlo-validate two trend-following crypto strategies on BTC, ETH and SOL, then dug into the generated code and the results myself. Here's how good Claude Sonnet 5 actually is for building trading strategies — and whether its speed makes it worth using over Opus. 00:00 Claude Sonnet 5 Is Here 0:54 Benchmarks: Sonnet 5 vs Opus 2:20 Connecting Jesse to Claude Code 3:23 The Research Prompt 4:53 The Agent's Results 6:41 Strategy 1 Deep-Dive 10:12 Monte Carlo Overfit Check 11:16 Reviewing Strategy 2 13:05 Inside the Generated Code 15:29 Final Verdict 👉 Get these strategies code: https://jesse.trade/strategies/tftrailbreakout?utm_source=sonnet5 https://jesse.trade/strategies/tfatrexitbreakout?utm_source=sonnet5 👉 Join our FREE Discord community: https://jesse.trade/discord 👉 Follow our Telegram channel: https://jesse.trade/telegram 👉 Apex signup URL for 25% fee discounts: https://jesse.trade/apex 👉 Bybit signup URL:: https://jesse.trade/bybit 👉 Explore my other strategies: https://jesse.trade/strategies?utm_source=sonnet5
