The main feature of these indicators is their continuous operation, which means that you can use them both for real trading and for teaching trading strategies on history, since this is a passage from the beginning to the end of the stream of candles. This approach allows you to reduce the number of necessary calculations by tens of times and is the most optimal in terms of performance.

This method allows you to get the current value of the indicator, usually performed according to the data of a closed candle. The method call affects all subsequent calculations of the indicator readings.

The method of calculating the instantaneous value of the indicator allows you to obtain information about the indicator readings in real time, without affecting future readings. This allows you to work with the indicator inside the candle.

Releases are available under Node Package Manager (npm):

npm install @debut/indicators

import { SMA } from '@debut/indicators';
const sma = new SMA(4); // Create SMA with 4 period

// SMA workflow
//=> [ '2.50', '3.50', '4.50', '5.50', '6.50', '7.50' ]
//=>   │       │       │       │       │       └─(6+7+8+9)/4
//=>   │       │       │       │       └─(5+6+7+8)/4
