Two brains, one terminal — Claude writes the trading code, ChatGPT reviews it, and the entire setup takes five minutes. I learned this yesterday… and it’s already changed how I’m building every agent in my £50K → £500K challenge. Here’s the problem no one talks about: When you ask Claude to review code Claude just wrote, it’s the same model, with the same training, checking the same work. Same blind spots. Same assumptions. It’s a student marking their own exam. For landing pages, that’s fine. For agents trading real money… it’s expensive. I’ve already lost thousands to gaps I didn’t know existed. So I installed OpenAI’s Codex CLI inside my Claude Code terminal and used it to review my Red Day DCA strategy — the dip-buying agent running my entire portfolio. It found: 14 issues Across 6 categories 5 rated critical or high One of them? A trigger that bypassed my strategy’s hard ceiling — meaning it could place buy orders above the price I explicitly told it to stop at. That’s what a second model — with a different training set — finds in minutes. This is the dual-brain setup every serious AI trader should be running. ⚠️ DISCLAIMER: Nothing in this video constitutes financial, investment, or tax advice. I am not a financial adviser.
