Show HN: I'll backtest your trading strategy for free

We've been working on https://www.growbell.com for a few months. It uses AI agents to parse natural language into trading strategies. That strategy then gets executed by our backtesting engine and spits out the results.

Here are some examples outputs:

It can handle commissions/slippage, etc but the main focus now is just testing it out in the wild. Some caveats:

1. Your strategy should trade equities (for now) 2. 20 years of data on SPY/QQQ, 2 years on other equities 3. It's only price/volume/technical data at the moment. News and fundaments are in the works.

Happy to answer any questions about tech stack! Otherwise you can leave your strategy description and I'll respond with a link to the results.
