Built a brutally honest futures backtester. Looking for beta testers
My live bot lost its first 3 trades in 2 days. The backtest was filling orders on the signal bar. Classic.
So I built Kapybar. Describe your strategy to Claude or ChatGPT (any language, voice, even a screenshot), confirm the rules, and it runs on 40 liquid CME futures (ES, NQ, CL, GC, ZN… + micros), 1-min to daily, back to 2008.
- next-bar fills, real rolls, commissions
- always vs buy-and-hold
- flags luck and edges that die with one more tick of cost
- last 2 years hidden until your final verdict (3 shots per market)
- prop-firm pass odds, minus luck
It tests your ideas, it doesn't make them up. If something passes, it means something.
Looking for serious rule-based traders. Needs Claude or ChatGPT Plus (MCP connector, 2 min setup). Free during beta.
No money, no broker access, no API keys.
Comment how you trade and I'll send an invite.
