* 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.

**Streaming-first technical indicators for Go, over the Wickra C ABI hub via cgo.**
|
|
|
|
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 Go binding; it consumes the C ABI hub through
|
|
cgo and exposes all 514 streaming-first indicators as idiomatic types.
|
|
|
|
## Install
|
|
|
|
Use the published **`wickra-go`** module, which bundles the prebuilt C ABI
|
|
library for every platform, so `go get` + `go build` works with no extra steps
|
|
(a C compiler is still required, as the binding uses cgo):
|
|
|
|
```bash
|
|
go get github.com/wickra-lib/wickra-go
|
|
```
|
|
|
|
```go
|
|
import wickra "github.com/wickra-lib/wickra-go"
|
|
```
|
|
|
|
`wickra-go` is generated from this directory by the release pipeline: it mirrors
|
|
the Go sources, the vendored C ABI header (`include/wickra.h`) and the prebuilt
|
|
libraries under `lib/<goos>_<goarch>/`. On Linux/macOS the library path is baked
|
|
in via rpath; on Windows the DLL must be discoverable at run time (next to the
|
|
executable or on `PATH`).
|
|
|
|
### Building from this repository (contributors)
|
|
|
|
This `bindings/go` directory is the development source. To build it directly,
|
|
compile the C ABI and stage the library into the per-platform directory cgo
|
|
links against:
|
|
|
|
```bash
|
|
cargo build -p wickra-c --release
|
|
mkdir -p bindings/go/lib/linux_amd64 # match your GOOS_GOARCH
|
|
cp target/release/libwickra.so bindings/go/lib/linux_amd64/ # Linux
|
|
cp target/release/libwickra.dylib bindings/go/lib/darwin_arm64/ # macOS (arm64)
|
|
cp target/release/wickra.dll bindings/go/lib/windows_amd64/ # Windows
|
|
```
|
|
|
|
## Quick start
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
|
|
wickra "github.com/wickra-lib/wickra/bindings/go"
|
|
)
|
|
|
|
func main() {
|
|
// Batch: run an indicator over a whole series (NaN at warmup positions).
|
|
prices := make([]float64, 1000)
|
|
for i := range prices {
|
|
prices[i] = 100.0 + float64(i)*0.1
|
|
}
|
|
sma, _ := wickra.NewSma(20)
|
|
defer sma.Close()
|
|
values := sma.Batch(prices)
|
|
|
|
// Streaming: the same indicator, fed tick by tick in O(1).
|
|
rsi, _ := wickra.NewRsi(14)
|
|
defer rsi.Close()
|
|
for _, price := range prices {
|
|
value := rsi.Update(price) // NaN during warmup, no recomputation
|
|
if value > 70 {
|
|
fmt.Println("overbought")
|
|
}
|
|
}
|
|
_ = values
|
|
}
|
|
```
|
|
|
|
`Batch(prices)` and feeding the same prices through `Update()` produce identical
|
|
values — the equivalence is enforced by the test suite. Multi-output indicators
|
|
(MACD, Bollinger, ADX, …) return `(Output, bool)`, with `false` while warming up.
|
|
Every indicator owns a native handle freed by `Close()`; a finalizer is wired as
|
|
a backstop, but call `Close()` (e.g. with `defer`) to release memory promptly.
|
|
|
|
## Benchmark
|
|
|
|
`benchmarks/throughput.go` reports streaming and batch updates-per-second for
|
|
`SMA`, `ATR` and `MACD`. It measures this binding's FFI overhead, not a
|
|
cross-library ratio (the same Rust core runs under every binding) — see the
|
|
repository [BENCHMARKS.md](https://github.com/wickra-lib/wickra/blob/main/BENCHMARKS.md) §3.
|
|
|
|
```bash
|
|
cd benchmarks && go run .
|
|
```
|
|
|
|
## 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/go/`](https://github.com/wickra-lib/wickra/tree/main/examples/go)
|
|
|
|
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.

## 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.
