<script src="node_modules/@sunrise1002/tats/dist/browser.es6.js"></script>

For ES5 support it is necessary to include the babel-polyfill and respective file browser.js otherwise you will get an error. For example see index.html

Pattern detection

Pattern detection is removed from version 3.0, if you need pattern detection use v2.0

All indicators will be available in window object. So you can just use

sma({period : 5, values : [1,2,3,4,5,6,7,8,9], reversedInput : true});

or

SMA.calculate({period : 5, values : [1,2,3,4,5,6,7,8,9]});

API

There are three ways you can use to get the indicator results.

calculate

Every indicator has a static method calculate which can be used to calculate the indicator without creating an object.

const sma = require('@sunrise1002/tats').sma;
var prices = [1,2,3,4,5,6,7,8,9,10,12,13,15];
var period = 10;
sma({period : period, values : prices})

or

const SMA = require('@sunrise1002/tats').SMA;
var prices = [1,2,3,4,5,6,7,8,9,10,12,13,15];
var period = 10;
SMA.calculate({period : period, values : prices})

nextValue

nextValue method is used to get the next indicator value.

var sma = new SMA({period : period, values : []});
var results = [];
prices.forEach(price => {
  var result = sma.nextValue(price);
  if(result)
    results.push(result)
});

getResult

This a merge of calculate and nextValue. The usual use case would be

1. Initialize indicator with available price value

2. Get results for initialized values

3. Use
