July 12, 2026 How I built a browser terminal that lets you rewind any crypto move tick-by-tick

I kept missing the big ones. Every few days a coin would rip 100% and I'd think: what actually happened in the minutes before it moved? The order flow was right there - I just wasn't watching that pair at that second, and there was no way to rewind and look.

So I built EdgeDepth. The hard part was speed: it's a C++ terminal compiled to WebAssembly, rendering the chart, order book, tape and liquidation heatmap at 180 FPS in a browser tab. And it records every tick on 650+ Binance perps, all the time - so you can right-click any moment in the last 30 days and replay it deterministically, exactly as it happened.

The unlock: instead of asking "why didn't I catch that," you replay the 90 seconds before a cascade and start seeing the setup.

Every few days I'd watch some coin rip 100% and think - how did I miss that? What actually happened in the minutes before it moved? I want to see how the moved looked tick-by-tick BEFORE it took off.
