Note: you can move files from node_modules to somewhere else you want to like dist, public, etc.

OR you can use unpkg:

https://unpkg.com/@ixjb94/indicators@latest/dist/browser-indicatorsNormalized-sync.js

Indicators Consists Of

Indicators consists of these classes:
1- Indicators: new Indicators()
2- IndicatorsNormalized: new IndicatorsNormalized()
3- IndicatorsSync: new IndicatorsSync()
4- IndicatorsNormalizedSync: new IndicatorsNormalizedSync()

Q: What is the difference between Indicators and IndicatorsNormalized?
A: IndicatorsNormalized will fill the gap for you, example (SMA 3 with 5 closes):

[NaN, NaN, 1, 2, 3]

But the Indicators will give you the SMA3 with 5 closes like this:

[1, 2, 3]

Note: Please note that the performance between IndicatorsNormalized and Indicators are the same,
so it's better to use IndicatorsNormalized.

Examples

Note: Everything isPromised so you need to do .then or await
unless you use Sync versions.

let ta = new Indicators()

ta.sma(close, 20)
ta.rsi(close, 14)
