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), PSAR, MFI, Price Envelopes..
If you're are interested in purchasing them, developing new indicators or any other tools, please contact us at: start@blacklabel.pl You may also want to check our other demo here: http://demo.blacklabel.pl.

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);

Code

The latest code is available on github: (https://github.com/blacklabel/indicators/)

                title: {
                    text:'My RSI title'

Parameters

Property	Type	Description
id	String	id of series
type	String	type of indicator (one of: `sma`, `ema`, `atr`, `rsi`)
showInLegend	Boolean	determines if indicator should be visible in the legend. Defaults to `false`.
name	String	name is used in legend and tooltip to display indicator. By default it's the same as type.
styles	Object	color, dashstyle, width etc. for a indicator line
yAxis (ATR/RSI)	Object	yAxis object like in Highcharts, options for additional yAxis
params	Object	config options for indicator
params.approximation (SMA/EMA/ATR/RSI)	String/Function	The same property as in `dataGrouping.approximation` for Highstock. Supported since version 2.0.0. Defaults to `"average"`.
params.period (SMA/EMA/ATR/RSI)	Number	base perdiod for indicator (it's number of points to be calculated). Defaults to `14`.
params.index (SMA/EMA)	Number	y-value index. Useful when using candlestick/ohlc/range series to determine which value (open/high/low/close) should be used in indicator. Defaults to `0`.
params.overbought (RSI)	Number	overbought value between 0-100. Defaults to `70`.
params.oversold (RSI)	Number	oversold value between 0-100. Defaults to `30`.
params.decimals (RSI)	Number	Precision for the calculations. For example decimals=1 will cut off value 123.4567 to 123.4. Higher value provides more accurate values, but will cost performance. Defaults to `4`.
tooltip.pointFormat	String	`point.color` and `point.y` return values from indicator. Disabled by default.

New options/methods in Chart:

Method	Version:	Description
chart.addIndicator(options, [redraw])	v 1.0.0+	Add new indicator with given options. Optionally redraw chart.
chart.indicators.allItems	v 1.0.0+	Array containing all indicators.
chart.alignAxes	v 1.0.9+	`true`/`false`. When idicator requires separate yAxis (like ATR or RSI) then indicators plugin will update heights of the axes to fit plotting area. Disable it and set `yAxis.top` and `yAxis.height` when you want different heights for the y-axes. Defaults to `true`. Note: When disabled, top and height options need to be set for all axes for better view.
tooltip.enabledIndicators	v 1.0.0+	`true`/`false`, show indicators in tooltip. Disabled by default.
Highcharts.approximations	v 2.0.0+	Object containing built-in approximations (functions) in Highstock. For more details see `dataGrouping.approximation`

Indicator object

Method	Description
indicator.update(options)	Update indicator with given options
indicator.destroy()	Destroy indicator
indicator.setVisible(true\|false)	Hide or show indicator.
