wickra 0.8.6

Streaming-first technical indicators: incremental, fast, install-free.

Streaming-first technical indicators. Install with pip install wickra — no system dependencies.

Wickra is a multi-language technical-analysis library with a Rust core and native bindings for Python, Node.js and WebAssembly, plus a C ABI that C, C++, C# / .NET, Go, Java, R and any other C-capable language links against. Every indicator is a state machine that updates in O(1) per new data point, so live trading bots and historical backtests share the exact same implementation.

import numpy as np
import wickra as ta

# Batch: classic TA-Lib-style usage
prices = np.linspace(100, 200, 1000)
rsi = ta.RSI(14)
values = rsi.batch(prices)              # numpy array, NaN during warmup

# Streaming: same indicator, fed tick by tick
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")

Documentation

Full documentation lives at docs.wickra.org:

• Quickstarts — Rust, Python, Node, WASM, C, C#, Go, Java, R.
• Indicators — a per-indicator deep dive (formula, parameters, warmup) for every one of the 514 indicators; start at the indicators overview.
• Reference — warmup periods, streaming vs batch, indicator chaining, the data layer.
• Guides — Cookbook, TA-Lib migration, FAQ.

Why Wickra

Most TA libraries are fast, or multi-language, or broad. Wickra refuses to pick. It's the streaming-first engine built for the workload the others treat as an afterthought — live, tick-by-tick data — without giving up the breadth of a full batch library, and without making you reimplement your indicators four times to get there.

• The biggest streaming-native catalogue, period. 514 indicators across 24 families — candlesticks, harmonic & chart patterns, market profile, market breadth, Renko/Kagi/Point&Figure bars, Ehlers DSP cycles, risk/performance metrics — every single one updating in O(1) per tick. TA-Lib ships ~150 and none of them stream.
• One Rust core, five first-class targets. Native Python · Node.js · WebAssembly · Rust plus a C ABI for C / C++, C# / .NET, Go, Java, R and any other C-capable language — identical math, identical results, zero per-language reimplementation and zero GIL bottleneck.
• Correct by construction, not by hope. Every update validates its input, runs a real warmup, and returns an Option so a single bad tick can't silently poison state. batch == streaming is bit-exact, fuzzed and 100 %-line-covered for all 514 indicators.
• Orders of magnitude faster where it counts. In streaming Wickra is 11–56× faster than the only other incremental peer and thousands of times faster than recompute-on-every-tick libraries. On batch it wins several rows outright and trades the simple recurrences (SMA, EMA, MACD) for its guarantees — and the losses are shown, not hidden.
• Install in one line, anywhere. pip install wickra / npm install wickra — precompiled wheels and binaries, no C toolchain, none of TA-Lib's setup pain. macOS · Linux · Windows.
• Batteries included. Indicator chaining, a streaming OHLCV CSV reader, and a live Binance kline feed ship in the box.
• Truly permissive. MIT OR Apache-2.0 — drop it straight into commercial and closed-source work.

Every other library forces one of those compromises. Wickra doesn't:

Library	Install	Streaming	Languages	Indicators	Active
★ Wickra	clean	yes, O(1)	Rust · Python · Node · WASM · C · C# · Go · Java · R	514	yes
kand	clean	yes	Python · WASM · Rust	~60	yes
ta-rs	clean	yes	Rust only	~30	stale
yata	clean	partial	Rust only	~35	yes
TA-Lib	yes (C deps)	no	many bindings	~150	barely
pandas-ta	clean	no	Python	~130	slow
finta	clean	no	Python	~80	stale
talipp	clean	yes	Python	~40	yes

Broad, multi-language, streaming-native and honest about its trade-offs — at the same time. That's the combination no one else ships.

Why Wickra exists

Wickra started as a personal itch. The existing TA libraries never quite fit the projects I was building, so I decided to build one from the ground up — partly to learn, partly because I genuinely enjoy taking something that already exists and trying to do it differently (and, ideally, better). It's open source because the useful version of that itch is the one other people can build on too.

Benchmarks

Wickra updates every indicator in O(1) per tick. In streaming — the workload it is built for — it is 11–56× faster than the only other incremental peer and thousands of times faster than recompute-on-every-tick libraries. Batch is competitive: it wins several rows outright and trades a few µs elsewhere for None-warmup, NaN-safety and bit-exact batch == streaming.

Full tables (Rust + Python, streaming + batch) and how to reproduce them live in BENCHMARKS.md.

Indicators

514 streaming-first indicators across twenty-four families. Every one passes the batch == streaming equivalence test, reference-value tests, and reset semantics tests. Each has a per-indicator deep dive (formula, parameters, warmup) at docs.wickra.org.

Every candlestick pattern emits a signed per-bar value — +1.0 bullish, −1.0 bearish, 0.0 none — so the family drops straight into a feature matrix as one column each. Doji is direction-less by default (+1.0 / 0.0); construct it in signed mode (Doji::new().signed(), Doji(signed=True), new Doji(true)) for a dragonfly / gravestone ±1 reading.

Adding a new indicator means implementing one trait in Rust; every binding inherits it automatically (the C ABI — and the C#, Go, Java and R bindings generated from it — regenerate from the core).

Languages

Binding	Install	Example
Python (PyO3)	pip install wickra	examples/python/backtest.py
Node.js (napi-rs)	npm install wickra	examples/node/backtest.js
Browser / WASM	npm install wickra-wasm	examples/wasm/index.html
Rust	cargo add wickra	examples/rust/src/bin/backtest.rs
C / C++ (C ABI)	header + library, see bindings/c	examples/c/streaming.c
C# / .NET (C ABI)	dotnet add package Wickra, see bindings/csharp	examples/csharp/streaming
Go (cgo, C ABI)	go get github.com/wickra-lib/wickra/bindings/go, see bindings/go	examples/go/streaming
Java (FFM, C ABI)	Maven Central org.wickra:wickra, see bindings/java	examples/java (Streaming)
R (.Call, C ABI)	R CMD INSTALL bindings/r, see bindings/r	examples/r/streaming.R

Each binding ships several runnable examples (streaming, backtest, live feed); examples/README.md is the full cross-language index.

The wickra-core crate is unsafe-forbidden, so the native bindings are memory-safe end to end. The C ABI runs the same safe core; only its thin FFI boundary uses unsafe, and the caller owns handle lifetimes (_new / _free).

Rust API

use wickra::{Indicator, BatchExt, Chain, Ema, Rsi, Sma};

// Streaming or batch — same trait, same code.
let mut sma = Sma::new(14)?;
let out: Vec<Option<f64>> = sma.batch(&[1.0, 2.0, 3.0, 4.0, 5.0]);

let mut rsi = Rsi::new(14)?;
for price in live_feed {
    if let Some(v) = rsi.update(price) {
        println!("RSI = {v}");
    }
}

// Compose indicators: RSI(7) on top of EMA(14).
let mut chain = Chain::new(Ema::new(14)?, Rsi::new(7)?);
chain.update(price);

Live data sources

wickra-data (separate crate, opt-in) ships:

• A streaming OHLCV CSV reader.
• A tick-to-candle aggregator with arbitrary timeframes.
• A candle resampler for multi-timeframe analysis (1m → 5m → 1h on the fly).
• A Binance Spot WebSocket kline adapter (feature live-binance).

use wickra::{Indicator, Rsi};
use wickra_data::live::binance::{BinanceKlineStream, Interval};

let mut stream = BinanceKlineStream::connect(&["BTCUSDT".into()], Interval::OneMinute).await?;
let mut rsi = Rsi::new(14)?;
while let Some(event) = stream.next_event().await? {
    if event.is_closed {
        if let Some(v) = rsi.update(event.candle.close) {
            println!("RSI = {v:.2}");
        }
    }
}

A Python live-trading example using the public websockets package lives at examples/python/live_trading.py.

Testing

Every layer is covered; run the suites with the commands in Building everything from source.

• wickra-core: unit tests per indicator — textbook reference values (Wilder RSI, Bollinger Bands, MACD, ATR, Stochastic), batch == streaming equivalence, reset semantics, NaN/Inf handling, and property tests. A catalogue-wide property harness (tests/invariants.rs) additionally asserts batch == streaming, reset == fresh, and non-finite-input rejection for every indicator and bar-builder.
• wickra-data: unit tests for CSV decoding, the tick aggregator, the resampler, and the Binance payload parser.
• bindings/python: pytest covering smoke checks, streaming/batch equivalence, reference values, lifecycle, input validation, and dict/tuple candle inputs.
• bindings/node: node --test cases for batch, streaming, and reference values across all indicators.
• bindings/wasm: wasm-bindgen-test cases for constructors, equivalence, and reference values.
• bindings/c: Rust unit tests over the FFI boundary, plus C and C++ smoke tests and offline example ctests run on the three OSes.
• bindings/csharp: dotnet test cases covering one indicator per FFI archetype (scalar/batch, multi-output, bars, profile, array input) plus SMA reference values.
• bindings/go: go test cases covering one indicator per FFI archetype (scalar/batch, multi-output, bars, profile, array input), reset, and lifecycle.
• bindings/r: testthat cases covering one indicator per FFI archetype (scalar/batch, multi-output, bars, profile, array input), reset, and validation.
• bindings/java: JUnit cases covering one indicator per FFI archetype (scalar/batch, multi-output, bars, profile, array input) plus batch equivalence.

The four C-ABI bindings (C#, Go, Java, R) additionally replay a shared, language-neutral golden fixture (testdata/golden/*.csv, generated by cargo run -p wickra-examples --bin gen_golden) and assert exact parity with the Rust reference outputs across every archetype (SMA, EMA, RSI, ATR, MACD, ADX, Beta), catching FFI wiring bugs the math-only core tests cannot see.

Contributing

Contributions are very welcome — issues, bug reports, ideas, and pull requests all land in the same place: https://github.com/wickra-lib/wickra.

A short orientation for first-time contributors:

• Adding an indicator. Implement the Indicator trait in crates/wickra-core/src/indicators/<name>.rs, wire it into indicators/mod.rs and the crate root, and add reference-value tests, a batch == streaming equivalence test, and (where it makes sense) a proptest. The four bindings inherit your indicator automatically once you expose it in the language wrappers.
• Fixing a numeric bug. Add a failing test that pins the textbook value first, then fix the math. Property tests in crates/wickra-core catch most regressions; please don't disable them.
• Improving a binding. Each binding lives under bindings/<lang> with its own tests; please keep the batch == streaming invariant.
• Style. cargo fmt --all + cargo clippy --workspace --all-targets -- -D warnings are CI gates; running them locally before pushing keeps reviews short.

For larger architectural changes, open an issue first so we can sketch the shape together before you invest the time.
