Show HN: I built a quantitative analysis tool to retail traders

Hi HN,

I’ve been trading for 10+ years, mostly focusing on quantitative techniques like mean reversion and statistical arbitrage (pair trading). Over time, I’ve felt that many of the tools for these strategies are either too expensive, too slow, or simply not built with retail traders in mind.

So we decided to build QuantLens, a web-based tool that provides quantitative insights for the US stock market. Our goal is to make powerful quant tools accessible to everyone, not just institutions.

Key features:

Pair Trading: Find cointegrated stock pairs and analyze spread, z-score, divergence, and correlation.

Mean Reversion: Identify stocks deviating significantly from their historical mean.

Sector Analysis: Get a top-down view using sector-wide trends and relative performance.

Clean, fast UI: Designed to be lightweight and simple to explore.

This is still very much a work in progress, and we are actively building more features.

We would love to hear your feedback on: The concept The UI/UX Features you think would be useful for serious traders
