Completes the F1 family (Simple & Weighted MAs). The Rust core for both SMMA (Wilder's RMA) and TRIMA (triangular MA) already landed; this adds the remaining Definition-of-Done steps: - Python: PySmma / PyTrima PyO3 classes + module registration + .pyi stubs. - Node: SmmaNode / TrimaNode via the scalar-indicator macro; index.d.ts and index.js updated for the two new classes. - WASM: WasmSmma / WasmTrima via the scalar-indicator macro. - Wiki: Indicator-Smma.md and Indicator-Trima.md (full pages) plus rows in Indicators-Overview.md and entries in Home.md. cargo fmt + clippy (core/wickra/data/wasm/node) clean; 208 core tests, 25 data tests and 31 doctests green.
@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');
}
