I've spent years stitching together Jupyter notebooks, backtrader, broker APIs, and spreadsheets for risk tracking. CPZAI replaces all of that. I built a momentum strategy, backtested it against 20 years of data, connected my broker, and had it running in paper trading — all within a single session. The risk management tools alone are worth it; scenario testing and drawdown analysis are baked into the workflow, not bolted on as an afterthought.

The AI strategist (Simons) is genuinely useful — not a gimmick chatbot. It helped me debug a position sizing issue and suggested a volatility filter I hadn't considered. The strategy builder uses Python, so there's no proprietary language to learn.
