Node

npm install wickra

The package ships native bindings (built with napi-rs) and pulls in the right platform subpackage automatically — no node-gyp, no post-install build step.

• Latest: wickra 0.4.5
• Supported Node: 18 LTS and 20 LTS, on Linux x64 / arm64, macOS x64 / arm64, Windows x64. (Windows ARM64 is tracked but blocked on an npm name-publishing filter — see the release notes for status.)

Streaming

import { RSI } from 'wickra'

const rsi = new RSI(14)
for (const price of liveFeed) {
  const v = rsi.update(price)
  if (v != null && v > 70) console.log('overbought', v)
}

Batch (returns a Float64Array)

import { EMA } from 'wickra'

const ema = new EMA(20)
const out = ema.batch(prices)        // Float64Array, NaN during warmup

Multi-output indicators

import { MACD, BollingerBands } from 'wickra'

const macd = new MACD(12, 26, 9)
const out = macd.update(price)
// → { macd, signal, histogram } or null

const bb = new BollingerBands(20, 2.0)
const band = bb.update(price)
// → { upper, middle, lower, stddev } or null
