I built this because I wanted to track the relationship between two assets—but no exchange or TradingView chart existed for it. I needed a way to visualize this ratio historically and in real time, so I made a simple, open-source ratio tracker using WebSockets and TradingView Lightweight Charts.

What It Does:

Continuously tracks a custom price ratio in real-time Uses WebSockets (Binance API) for live market updates Displays historical trends with TradingView Lightweight Charts Works on mobile & desktop (PWA-ready, no backend) Live demo: https://neogas.eluvade.com GitHub repo: https://github.com/Eluvade/neogas

I figured others might have custom market relationships they want to track, so it’s fully open-source. You can modify it, add new pairs, or even integrate alerts.

Would love feedback—how else would you use a custom ratio tracker like this?
