got tired of closed orderflow tools. wanted to own the stack and learn more so i built cryexc, my free crypto orderflow tool using imgui/c++/wasm two modes - demo: browser connects to exchanges (realtime) - self-hosted: your own backend for historical data link/demo below 👇

crypto liquidity is fragmented across dozens of markets watching just binance means you're missing depth on bybit, okx, etc by the time you check all tabs, the market moved without you so i built an orderbook aggregator and you can use it for free 1/n

working on imgui aggregated orderbook heatmaps toggle and merge liquidity across multiple venues demo runs 100% in-browser btw (connecting directly to exchange websockets), but can connect my backend to aggregate much more all running smoothly alongside the footprint charts

working on multi-symbol support for cryexc few people asked for this, select between binance perps >$5m volume (if binance is blocked in your region, you get top hyperliquid symbols) tick size is tricky to generalize across all alts (still tuning it), but starting to look good

new day new features. focusing on QOL today - theme engine + default presets (what am I missing?). theming surprisingly easy with imgui - local state persistence. used EM_JS to bridge c++ to browser localstorage now it remembers exact layout, tabs, and settings after reload
