Candle batch() methods that index parallel high/low/close/volume arrays without first checking their lengths panic on a length mismatch. Adds an equal-length guard returning a clean error to the 11 affected Node methods (Stochastic, ADX, CCI, WilliamsR, MFI, PSAR, Keltner, Donchian, VWAP, AO, Aroon), the 10 affected WASM methods, and the 8 affected Python methods (WilliamsR, ADX, MFI, PSAR, Keltner, VWAP, AO, Aroon) -- matching the guard ATR/OBV already had. Verified in Node: mismatched arrays now throw instead of crashing.
@wickra/wickra
Node.js bindings for the Wickra streaming-first technical indicators library.
Install
Once published, install per platform via the precompiled native package:
npm install @wickra/wickra
Build from source
cd bindings/node
npm install
npm run build
npm test
The native module is built via napi-rs. The build script
produces a wickra.<platform>-<arch>.node binary in the package root that
index.js loads at runtime.
Usage
import { SMA, RSI, MACD, version } from '@wickra/wickra';
console.log('wickra', version());
// Batch:
const prices = Array.from({ length: 1000 }, (_, i) => 100 + Math.sin(i * 0.1) * 5);
const rsi = new RSI(14).batch(prices);
// Streaming:
const macd = new MACD(12, 26, 9);
for (const p of livePriceStream) {
const v = macd.update(p);
if (v && v.histogram > 0) console.log('bullish crossover candidate');
}
