About Wickra Synth

Wickra Synth generates deterministic synthetic market microstructure — OHLCV candles, order-book snapshots, trades and funding — from a single seed. A generation is a JSON document — data, not code — so the exact same synthetic market is drawn in every one of ten languages and is byte-for-byte identical for a given seed.

What makes it different

• One seed, one market. A fixed portable PRNG (SplitMix64 seeding xoshiro256++) lives only in the Rust core, so a given seed yields the identical stream on every platform and through every binding — no wall-clock, no OS entropy.
• The spec is data. A serde GenSpec — a seed, a bar count, a start_price, a list of regimes and a microstructure block. Because it is data, it crosses the C ABI and WASM unchanged.
• Full microstructure. Not just a price line: OHLCV candles plus order-book snapshots, trades and funding samples, mirroring the JSON shapes of the rest of the ecosystem.
• Deterministic, proven. The same seed replays the exact same stream, pinned by a golden corpus replayed through all ten bindings in CI.

Why it exists

Realistic market data for tests, training and demos is hard to source and rarely reproducible. Wickra Synth defines the generator once, in Rust, and exposes it as a JSON-over-C-ABI data API to Rust, Python, Node.js, WASM and — over a C ABI — C, C++, C#, Go, Java and R. The spec itself is portable JSON, so the same synthetic market runs anywhere and feeds a backtest, a screen or an RL environment unchanged.
