From Typewriters to Transformers: AI Is Just the Next Tools Abstraction (hardcoresoftware.learningbyshipping.com)

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:

https://growbell.com/strategy/public/mkxvyv https://growbell.com/strategy/public/xgiieo

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 we'll respond with a link to the results.

Seems interesting. However, 2 years of data is nothing when evaluating equity patterns, so users beware (recommend this as educational only). I'd personally want the performance data correlated with things like interest rates, inflation, unemployment, international trade data, etc so that equity performance data has more context.

But if it does work, let me know the next moonshot since I'm about to be fired.

The 2 years is only temporarily. To get more years of data we have to either A) pay Polygon $$$ or B) pull poor quality data from Yahoo finance. Until there's more product/market fit, we're refraining from A.

Your additional correlations are on point. Those fundamentals will be coming in before the end of summer. Sign up for the beta waitlist if you want to give it a go.

Or if you have a strategy you want to see tested, happy to give it a go and return the link!

And good luck on your next opportunity. You'll find something great.
