Mirror examples/python/live_trading.py for the Node binding: connect to the public Binance kline WebSocket, stream close prices through RSI / MACD / Bollinger Bands, and print BUY/SELL candidate signals when all three agree. The symbol and interval are validated before being spliced into the stream URL, and non-kline frames (acks, heartbeats) are skipped. Uses the standard `ws` package, added as a devDependency so it installs with `npm install` for anyone running the examples but never reaches a consumer of the published package.
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
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';
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');
}
