no-talib is now renamed to talib-stream This lib for efficiently calculating weighted ta-lib metrics with streaming support.
npm install no-talibOften we need realtime calculation some weighted metric that requires previous knowledge, such as EMA, RSI, ATR. Ideally longer priods are better. But it would cost a lot of time to simply calculate from the beginning.
This lib is intended for fast calculating indicators from data stream.
npm i talib-stream --save
example code
const atrKeeperRes: any = [];
const atrKeeper = new AtrKeeper({ periods: period });
_.each(sampleCandles, c => {
atrKeeper.add({
close,
high,
low,
});
atrKeeperRes.push(atrKeeper.get());
});
