Indicators

Indicators - Highstock module

Indicators available in this plugin: SMA, EMA, ATR, RSI. You can use these indicators for free.

We also have other indicators available: Bollinger Bands, MACD, Momentum, CCI, Stochastic, Rate of Change (ROC), Accumulation / distribution (AD), Pivot Points, ZigZag, Weighted Moving Average (WMA), Price Envelopes.
If you're are interested in purchasing them, developing new indicators or any other tools, please contact us at: [email protected]

Requirements

  • Version 2.0+ requires the latest Highstock (v2.1.5+)
  • Version 1.1 requires Highstock v2.1.5
  • Version <1.1 supported since Highstock v1.3.9 to Highstock v2.1.4

Versions

  • 2.x - Improved logic for calculations and performance. Values are based on initial points, not grouped. When points are grouped by dataGrouping then indicators values are grouped too.
  • 1.x - Initial version of Indicators.js. Calculations are based on grouped points (aka dataGrouping)

Installation

  • Like any other Highcharts module (e.g. exporting), add <script> tag pointing to indicators.js below Highcharts script tag. Then attach all required indicators (like ema.js, rsi.js).

  • For NPM users:

    var Highcharts = require('highcharts/highstock');
    require('indicators')(Highcharts);
    require('sma')(Highcharts);
    require('ema')(Highcharts);
    require('rsi')(Highcharts);
    require('atr')(Highcharts);
  • For BOWER users:
bower install highcharts-indicators
