About Wickra X-Ray

Wickra X-Ray is a free explorer that shows, historically, what only Wickra computes — footprint, order-book heatmap, liquidation map and funding/OI divergence. One data-driven core folds a recorded dataset into render data-models; a front-end just draws them.

What makes it different

• Four microstructure panels. Footprint (traded volume per price bin, split by aggressor side), order-book heatmap (resting liquidity over a time × price grid), liquidation map (liquidation events clustered by price bin), and funding/OI divergence (funding, open interest and price on one time axis).
• Frames are data, not commands. xray-core folds an XraySpec over a recorded dataset — trades, order-book diffs, funding and open interest — into XrayFrame render data-models, never renderer calls. A front-end simply draws the frame.
• Deterministic core. The parallel (rayon) and sequential (WASM fallback) builds are byte-for-byte identical, and the frame crosses the C ABI and WASM unchanged.
• Free to explore. X-Ray reads recorded datasets and renders them; it never trades and needs no key.

Why it exists

Footprint, book heatmaps and liquidation maps are usually locked behind paid terminals. Wickra X-Ray computes them from open data and defines the surface once, in Rust, as a JSON-over-C-ABI data API (Xray::command), exposed to Rust, Python, Node.js, WASM and — over a C ABI — C, C++, C#, Go, Java and R, plus a web front-end (Vue + Canvas) that renders the frames in the browser.
