**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
bindings for Python, Node.js, and WebAssembly. 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.
```python
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")
```

## 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.
Plenty of TA libraries are fast. Each one forces a trade-off Wickra does not:
| Library | Install | Streaming | Languages | Indicators | Active |
|------------------|-------------|-------------|-----------------------------|-----------:|--------|
| **★ Wickra**| **clean** | **yes, O(1)** | **Python · Node · WASM · Rust** | **423** | **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 |
Wickra's edge is **breadth with reach**: 447 indicators that all update in O(1)
per tick and ship natively to Python, Node.js, WebAssembly and Rust from a
single engine.
**On speed — and why Wickra isn't the fastest.** It deliberately isn't. The
leaner Rust crates (kand, ta-rs) win several of the micro-benchmarks below, and
those losses are shown rather than hidden. The gap is a *choice*, not a ceiling:
every `update` validates its input, runs a real warmup before it emits a value,
and returns an `Option` so a single bad tick can't silently poison the state.
ta-rs, by contrast, hands back a bare `f64` from the first tick with no
validation. If Wickra threw all of that away — raw `f64` out, no checks, no
warmup contract — it would match or beat the leanest crate on every row. It
keeps the guarantees instead, and still wins RSI, Bollinger and ATR against kand.
What no other library matches is the *combination*: catalogue size, native O(1)
streaming, NaN-safety, and four first-class language targets at once.
## Benchmarks
Three comparisons, split by layer and mode. Read them as **relative** speedups
on identical input — absolute µs depend on CPU, memory clock and OS scheduler,
not a universal contract.
- **Reproduced on:** Windows 11 Pro 26200, AMD Ryzen 9 9950X, 64 GB DDR5,
Rust 1.92 (release: `lto = "fat"`, `codegen-units = 1`), Python 3.12.
- **Reproduce yourself:**
- Rust core vs Rust crates: `cargo bench -p wickra-bench`
- Python vs Python libs: `pip install -e bindings/python[bench]` then
`python -m benchmarks.compare_libraries` (auto-detects installed peers).
### 1. Rust core vs the other Rust TA crates
Like-for-like, no language-binding overhead, over a 50 000-bar series (µs for
the whole series, lower = faster). This is the honest engine comparison —
Wickra wins some and loses some, and both are shown.
**Streaming** (one value fed per `update`):
| Indicator | **★ Wickra** | kand | ta-rs | yata |
|------------------|------------------:|-----:|------:|-----:|
| SMA(20) | 50 | 38 | 47 | 38 |
| EMA(20) | 154 | 69 | 56 | 69 |
| RSI(14) | 164 | 216 | 74 | — |
| MACD(12, 26, 9) | 275 | 143 | 66 | — |
| Bollinger(20, 2) | **128 ★** | 248 | 168 | — |
| ATR(14) | 152 | 166 | 61 | — |
**Batch** (whole series at once). Only Wickra and kand expose a batch API;
ta-rs and yata are streaming-only.
| Indicator | **★ Wickra** | kand |
|------------------|------------------:|-----:|
| SMA(20) | 82 | 42 |
| EMA(20) | 159 | 74 |
| RSI(14) | **253 ★** | 274 |
| MACD(12, 26, 9) | 681 | 283 |
| Bollinger(20, 2) | **445 ★** | 462 |
| ATR(14) | 175 | 173 |
ta-rs is the per-indicator speed champion on almost every row — it returns a
bare `f64` with no warmup state and no input validation, trading away the
`None`-warmup and NaN-safety semantics Wickra keeps. Against kand, Wickra wins
streaming RSI, Bollinger and ATR (and batch RSI + Bollinger); Bollinger is the
one row where Wickra is the outright fastest of all four. The leaner crates
still win the pure recurrences (EMA, MACD) and SMA. yata exposes only SMA/EMA as
raw-value methods, so its other rows are omitted rather than faked.
### 2. Python vs the Python TA ecosystem — batch
Full pass over a 20 000-bar series, µs/op (lower = faster). **★** per row.
| Indicator | **★ Wickra** | finta | TA-Lib | tulipy |
|------------------|------------------:|---------------------|--------|--------|
| SMA(20) | **59.6 ★** | 354.2 (5.9× slower) | ⧗ | ⧗ |
| EMA(20) | **88.4 ★** | 309.3 (3.5× slower) | ⧗ | ⧗ |
| RSI(14) | **77.3 ★** | 1 283 (16.6× slower)| ⧗ | ⧗ |
| MACD(12, 26, 9) | **116.4 ★** | 529.5 (4.6× slower) | ⧗ | ⧗ |
| Bollinger(20, 2) | **146.0 ★** | 1 246 (8.5× slower) | ⧗ | ⧗ |
| ATR(14) | **135.8 ★** | 3 812 (28× slower) | ⧗ | ⧗ |
> ⧗ = published by the CI Linux job. TA-Lib and tulipy ship C extensions that
> don't build cleanly on every desktop, so their canonical numbers come from the
> `cross-library-bench` workflow rather than this local table. pandas-ta needs
> Python ≥ 3.12 and isn't in the 3.11 CI matrix. The script auto-detects
> whichever peers are installed in your environment.
### 3. Python — streaming (per-tick latency)
Seed 5 000 bars, then feed ticks one at a time. talipp is the only Python peer
with a true incremental API; batch-only libraries like TA-Lib must recompute the
entire history on every tick — Wickra updates in O(1).
| Indicator | **★ Wickra (per tick)** | talipp (per tick) |
|------------------|------------------------------:|-------------------------|
| SMA(20) | **0.067 µs ★** | 0.63 µs (9.4× slower) |
| EMA(20) | **0.051 µs ★** | 0.63 µs (12.2× slower) |
| RSI(14) | **0.053 µs ★** | 1.00 µs (19.1× slower) |
| MACD(12, 26, 9) | **0.071 µs ★** | 3.64 µs (51.5× slower) |
| Bollinger(20, 2) | **0.085 µs ★** | 4.87 µs (57.2× slower) |
Run the suite yourself:
```bash
cargo bench -p wickra-bench # Rust core vs kand / ta-rs / yata
pip install -e bindings/python[bench] # Python peers
python -m benchmarks.compare_libraries
```

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; all four bindings
inherit it automatically.
## 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` |
Each binding ships several runnable examples (streaming, backtest, live feed);
[`examples/README.md`](examples/README.md) is the full cross-language index.
The wickra-core crate is `unsafe`-forbidden, so every binding inherits a
memory-safe implementation.
## Rust API
```rust
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`).
```rust
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`.

Wickra's own regression benchmarks live in `crates/wickra/benches/`; the
cross-library comparison against kand, ta-rs and yata lives in the internal
`crates/wickra-bench/` crate. Runnable Rust examples live in the workspace member
crate at `examples/rust/`. There is no top-level `benches/` directory.
## Building everything from source
```bash
# Rust core + tests
cargo test --workspace
cargo clippy --workspace --all-targets -- -D warnings
cargo bench -p wickra # Wickra's own regression benchmarks
cargo bench -p wickra-bench # cross-library comparison (kand, ta-rs, yata)
# Python binding (requires Rust toolchain + maturin)
cd bindings/python
maturin develop --release
pytest
# WASM binding (requires wasm-pack + wasm32-unknown-unknown target)
wasm-pack build bindings/wasm --target web --release --features panic-hook
# Node binding (requires @napi-rs/cli)
cd bindings/node && npm install && npm run build && npm test
```
## Testing
Every layer is covered; run the suites with the commands in
[Building everything from source](#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.
- `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.
## 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.
