* docs: standardise language naming and add binding security sections Canonical binding list everywhere: Rust, Python, Node.js, WASM, C, C++, C#, Go, Java, R. Use C# (not .NET) as the language label, WASM (not WebAssembly) in prose, and frame the C ABI as a hub rather than a list item. - Bump stale indicator counts (200+ -> 514) and family count (sixteen -> twenty-four) in the Node/Python/WASM and docs READMEs. - Add a short Security section to all eight binding READMEs. - Relabel benchmark rows (C -> C / C++, C# / .NET -> C#). - Fix the 'language stecker' wording in the C#/Go/R API intros. - Documentation only; no code or public API changes. * release.yml: extend install snippets and expose version output Add the missing registry installs to the release body (dotnet, go, Gradle/ Maven Central, r-universe) alongside cargo/pip/npm, and expose a v-stripped 'version' output from the tag step for the Gradle coordinate. Also fix the C-ABI language order in the assets note (C# before Go). * release.yml: correct the release body (10 languages, all registries) Reframe the tagline to '10 languages' (native Rust/Python/Node.js/WASM + a C ABI hub for C, C++, C#, Go, Java, R) instead of '4 language registries', note that C#/Java/Go/R publish to NuGet/Maven/Go/r-universe via their own jobs, and tidy the Node.js label and the C-ABI hub list.

# Wickra — Python

**Streaming-first technical indicators for Python. `pip install wickra` — no
|
|
system dependencies, no C build tooling.**
|
|
|
|
Wickra is a multi-language technical-analysis library with a Rust core and
|
|
bindings for Python, Node.js and WASM, plus a C ABI for C, C++, C#, Go, Java, R and any
|
|
other C-capable language. Every indicator is an O(1)
|
|
streaming state machine, so live trading bots and historical backtests share
|
|
the exact same implementation. This package is the Python binding (PyO3); it
|
|
exposes all 514 streaming-first indicators across twenty-four families.
|
|
|
|
## Install
|
|
|
|
```bash
|
|
pip install wickra
|
|
```
|
|
|
|
Pre-built wheels ship for Linux, macOS, and Windows — there is nothing to
|
|
compile and no C library to track down.
|
|
|
|
## Quick start
|
|
|
|
```python
|
|
import numpy as np
|
|
import wickra as ta
|
|
|
|
# Batch: classic TA-Lib-style usage over a whole array.
|
|
prices = np.linspace(100, 200, 1000)
|
|
rsi = ta.RSI(14)
|
|
values = rsi.batch(prices) # numpy array, NaN during warmup
|
|
|
|
# Streaming: the same indicator, fed tick by tick in O(1).
|
|
rsi = ta.RSI(14)
|
|
for price in live_feed:
|
|
value = rsi.update(price) # no recomputation over history
|
|
if value is not None and value > 70:
|
|
print("overbought")
|
|
```
|
|
|
|
`batch(prices)` and feeding the same prices through `update()` produce
|
|
identical values — the equivalence is enforced by the test suite.
|
|
|
|
## Benchmark
|
|
|
|
Two benchmarks ship with the binding:
|
|
|
|
- `benchmarks/throughput.py` — streaming and batch updates-per-second for `SMA`,
|
|
`ATR` and `MACD`. This is per-binding FFI overhead (the same Rust core runs
|
|
under every binding), not a cross-library ratio.
|
|
- `benchmarks/compare_libraries.py` — the cross-library comparison against
|
|
TA-Lib, pandas-ta, tulipy and finta that backs the headline speedups.
|
|
|
|
```bash
|
|
maturin develop --release
|
|
python -m benchmarks.throughput
|
|
python -m benchmarks.compare_libraries # cross-library; auto-detects installed peers
|
|
```
|
|
|
|
See the repository [BENCHMARKS.md](https://github.com/wickra-lib/wickra/blob/main/BENCHMARKS.md).

|

|
## Documentation
|
|
|
|
The full indicator catalogue, guides, quickstarts, and API reference live in
|
|
the main repository and documentation site:
|
|
|
|
- **Repository & full indicator list:** <https://github.com/wickra-lib/wickra>
|
|
- **Docs** (quickstarts, cookbook, TA-Lib migration): <https://docs.wickra.org>
|
|
- **Runnable examples:** [`examples/python/`](https://github.com/wickra-lib/wickra/tree/main/examples/python)
|
|
|
|
Wickra ships native bindings for Python, Node.js, WASM and Rust, plus a
|
|
C ABI hub that any C-capable language (C, C++, C#, Go, Java, R) links against —
|
|
all exposing the same indicators from the shared, `unsafe`-forbidden Rust core.
|
|
|
|
## Security
|
|
|
|
Found a security issue? **Please don't open a public issue.** Report it privately
|
|
via the affected repository's *Security* tab (*"Report a vulnerability"*) or email
|
|
**support@wickra.org** with a subject line starting `[wickra security]`. Full
|
|
policy: <https://github.com/wickra-lib/wickra/blob/main/SECURITY.md>.

|
## Disclaimer
|
|
|
|
Wickra is an indicator toolkit, not a trading system. The values it computes
|
|
are deterministic transforms of the input data — they are not financial advice
|
|
and do not predict the market. Any use in a live trading context is at your own
|
|
risk. The library is provided **as is**, without warranty of any kind.
