Converts OHLC Candlestick data to Heikin-Ashi

The conversion is done based on this:

``javascript
HA.Close = (Open(0) + High(0) + Low(0) + Close(0)) / 4;
HA.Open = (HA.Open(-1) + HA.Close(-1)) / 2;
HA.High = MAX(High(0), HA.Open(0), HA.Close(0));
HA.Low = Min(Low(0), HA - Open(0), HA.Close(0));

// Where (0) means current candle, and (-1) means the previous candle
`

The output is an array of the same size

`javascript
let result = [{
open: 100,
high: 200,
low: 10,
close: 50,
}, ...
]
`

Install

`bash
npm i -S heikinashi
`

Usage

`javascript
var HeikinAshi = require("heikinashi");

let result = HeikinAshi([
{
time: 1525651200,
close: 9377.81,
high: 9662.23,
low: 9202.13,
open: 9643.99,
volume: 73842.44,
},
...
],
options{
overWrite: false, //overwrites the original data or create a new array
formatNumbers: false, //formats the numbers and reduces their significant digits based on the values
decimals: 4, //number of significant digits
forceExactDecimals: false //force the number of significant digits or reduce them if the number is high
});

console.log("result: ", JSON.stringify(result, null, 2));
``
