Wickra

Wickra is a family of 24 open-source trading libraries: a streaming-first indicator core and twenty-three data-driven products built on it. Every one of them is a Rust core with a CLI and the same ten-language binding surface — native Python, Node.js and WASM, plus a C ABI for C, C++, C#, Go, Java and R — released to crates.io, PyPI, npm, NuGet, Maven Central, the Go module proxy and R-universe from one pipeline, and checked byte-for-byte across all ten languages by a golden corpus in every repository.

▶ Live demos: all 514 indicators over real Binance market data, in your browser — live.wickra.org; a backtest whose equity curve builds bar by bar — backtest-live.wickra.org; one strategy spec running side by side in Python, Rust, JS and Go — playground.wickra.org. Zero backend, all of them.

Site: wickra.org · Docs: docs.wickra.org, and one site per product (table below)

The core in three lines, in Python:

import wickra as ta

rsi = ta.RSI(14)
for price in live_feed:
    value = rsi.update(price)   # O(1) — no recomputation over history
    if value is not None and value > 70:
        print("overbought")

Six layers, twenty-four repositories. The release badge is each repository's latest published version; the docs column is its own documentation site.

The core, in every language:

Every product installs the same way with its own name: pip install wickra-<name>, npm install wickra-<name> (and wickra-<name>-wasm for the browser), cargo install wickra-<name> for the CLI, dotnet add package Wickra.<Name>, org.wickra:wickra-<name> on Maven Central, go get github.com/wickra-lib/wickra-<name>-go, and the R package with the hyphen dropped (wickracopilot, wickrafeaturestore, …) from r-universe. The exact identifiers are the badges on each repository's README.

No C compiler, no headers, no Rust toolchain required to install the native packages — pre-built on every supported platform. The C ABIs ship the same way: a ready-to-link header + shared/static library per platform on every release.

Supported versions, family-wide: Rust 1.86 · Python 3.9 · Node.js 22 · WASM (any modern engine) · C99 · C++17 · .NET 8 · Go 1.23 · Java 22 · R ≥ 4.1 — the Requirements page has the per-language detail, and each product's README its own.

• One core, 514 indicators across twenty-four families, every one a state machine that updates in O(1) per new data point — the same code for the backtest and the live tick, and the same numbers in every product above.
• Data, not code. A strategy, a scan, a fingerprint, a proof — each is a JSON spec the Rust core executes, so the same spec runs unchanged from any of the ten languages and produces the same bytes.
• Identical across all 10 languages — proven, not promised. Every repository carries a golden corpus that CI replays through Rust, Python, Node.js, WASM, C, C++, C#, Go, Java and R and compares byte-for-byte.
• Zero third-party dependencies in every language, unsafe-forbidden Rust cores, hash-locked CI, SHA-pinned actions, signed commits and build provenance on every release — the same supply chain in all twenty-four repos.
• One release pipeline. A tag publishes to every registry at once; the org keeps a version snapshot of what each registry actually holds.

• wickra-docs — the core's documentation, live at docs.wickra.org: per-indicator deep-dives, quickstarts for every language, the cookbook and the TA-Lib migration guide
• webpage — the marketing site, live at wickra.org: landing page, live in-browser WASM demo, benchmarks
• wickra-live — live.wickra.org, every indicator over a real Binance feed in the browser
• wickra-backtest-live — backtest-live.wickra.org, the backtester compiled to WebAssembly
• wickra-playground — playground.wickra.org, one StrategySpec side by side in Python, Rust, JS and Go
• wickra-<name>-site — one VitePress site per product, deployed at <name>.wickra.org; wickra-<name>-go — the published Go module of each product, mirrored from bindings/go/ on every release

Please do not open a public issue for a security vulnerability in any repository of the family. Report it privately through that repository's Security tab ("Report a vulnerability") or by email to support@wickra.org with a subject line starting [wickra security]; every repository's SECURITY.md carries the same policy.

Every repository is dual-licensed under MIT or Apache-2.0 — OSI-approved, permissive open source, at your option.

If Wickra saved you time, the cheapest way to say thanks is to ⭐ a repo.
