Go

Verified against the Rust reference. Every one of Wickra's 514 indicators is replayed through all 10 languages and checked bit-for-bit against the Rust core's golden fixtures in CI — the math here is provably identical to every other binding (how).

The Go binding is a cgo shim on the C ABI hub. It links the prebuilt Wickra C ABI library and exposes all 514 indicators as idiomatic Go types.

• Distribution: standalone Go module (github.com/wickra-lib/wickra-go) with the prebuilt native libraries committed per platform, so go get builds with no extra steps.
• Built on: the C ABI hub via cgo, with wrappers generated from wickra.h.
• Memory model: opaque handles freed by Close(), with a runtime.SetFinalizer backstop; defer x.Close() for prompt cleanup.

The type shape

Every indicator is a type with Update / Batch / WarmupPeriod / IsReady / Reset / Close. Use defer x.Close() so the native handle is freed promptly.

import wickra "github.com/wickra-lib/wickra-go"

sma, err := wickra.NewSma(14) // ErrInvalidParams on invalid params
if err != nil {
	panic(err)
}
defer sma.Close()

w := sma.WarmupPeriod() // updates until ready: 14
v := sma.Update(42.0)   // NaN while warming up
ready := sma.IsReady()  // false until warmed up
sma.Reset()

The alt-chart bar builders (RenkoBars, KagiBars, …) have no WarmupPeriod / IsReady — a candle can complete 0..n bars, so they have no warmup.

Streaming

rsi, _ := wickra.NewRsi(14)
defer rsi.Close()
for _, price := range feed {
	v := rsi.Update(price)
	if !math.IsNaN(v) && v > 70.0 {
		fmt.Printf("overbought %.2f\n", v)
	}
}

Batch (one call over a whole series)

ema, _ := wickra.NewEma(20)
defer ema.Close()
values := ema.Batch(prices) // NaN at warmup positions

Multi-output indicators

Indicators with several outputs return a value plus a bool — false while warming up:

macd, _ := wickra.NewMacdIndicator(12, 26, 9)
defer macd.Close()
for _, price := range feed {
	if m, ok := macd.Update(price); ok {
		fmt.Printf("macd=%.4f signal=%.4f hist=%.4f\n", m.Macd, m.Signal, m.Histogram)
	}
}

Candle-input indicators take OHLCV plus a timestamp, e.g. atr.Update(open, high, low, close, volume, timestamp).
