This type of JavaScript Candlestick chart is used to observe price fluctuations while trading. This makes it useful to dynamically display data for both longer and shorter intervals. Get your hands on the most advanced data visualization library at a discounted price. Start creating more sophisticated financial charts to describe the price changes of a security or currency with SciChart.js. Our candlestick graphs support interactive elements including animation, zooming and panning. Our boilerplates integrate easily with all your JavaScript frameworks, including Angular, Vue, Blazor, React, Electron and Next.js.

The default is true when focusTarget is set to ‘category’, otherwise the default is false. Overrides the default format for various aspects of date/datetime/timeofday data types when used with chart computed minorGridlines. Five or more columns, where the first column defines X-axis values or group labels,
and each multiple of four data columns after that defines a different series.


Build incredible complex dashboards with SciChart.js, our High Performance JavaScript Chart Library. In the SciChart.js demo – Candlestick Charts – volume bars are docked to the bottom of the chart. Passes back the current legend zero-based page index and the total number of pages. Returns the vertical data value at yPosition, which is a pixel offset down from the chart container’s top edge.

  • The candlestick and OHLC charts are for showing financial data in a graph.
  • You can enable legends by setting showInLegend to true.
  • For example, the business days alone can be represented in a week here.
  • If you are new to the ChartJS library, how to create a bar chart is a simple example for getting started.
  • Other related customizations include exportEnabled, animationEnabled, etc.
  • Given example shows stock price comparison of AT&T vs Verizon in 2016 using Multi Series Candlestick Chart.

Let’s use the DateTime axis tick strategy with the origin set to the current day or defined date. Look at the lower wick of the candlestick to get the security’s lowest price for the specified time period. Candlestick patterns are particularly useful because they visually reveal key information that is hidden from the chart. To find the high price of the security for the chosen period, look at the candlestick’s upper wick.


Conversely, the candlestick turns red when the price opens and then falls. SciChart.js is the latest software to be added to our award-winning chart library portfolio. Our priority is to enable javascript candlestick chart the creation of high-performance JavaScript charts for all your digital applications. Returns an object containing information about the onscreen placement of the chart and its elements.

A candlestick chart is used to show an opening and closing value
overlaid on top of a total variance. Candlestick charts are often
used to show stock value behavior. By the way, AnyChart has its own online editor for data visualizations like charts, maps, and dashboards, called AnyChart Playground. This candlestick chart is available right there so you can play with its code in a convenient way. Since the dataset is pretty large, instead of inserting the data directly in the .html file, let’s put it in a CSV file for convenience.

Candlestick Series or JavaScript Stock Charts can be created using the FastCandlestickRenderableSeries type. All code and data are processed and rendered in the browser. For more information on how to use these events, see
Basic Interactivity,
Handling Events, and
Firing Events. Sets a tooltip action to be executed when the user clicks on the action text. Removes the tooltip action with the requested actionID from the chart. Returns the tooltip action object with the requested actionID.

Candlestick Graphs are mostly used to represent stock price, foreign exchange, commodity, etc. Given example shows stock price comparison of AT&T vs Verizon in 2016 using Multi Series Candlestick Chart. It also contains source code that you can edit in-browser or save to run locally.

Step 3: Prepare the data

DateTime data with irregular intervals can be shown on the DateTime category axis. For example, the business days alone can be represented in a week here. Investors can determine whether the closing price was higher or lower than the opening price by looking at the wide portion of the candlestick.

Final JavaScript Candlestick Chart Application

When the price of the security starts at a specific price and then rises, the candlestick turns green. Trading professionals seeking chart patterns can use candlesticks charts for their analysis. Many traders consider candlestick charts to be easier to read and more visually appealing than conventional bar charts. Replaces the automatically generated Y-axis ticks with the specified array. Each element of the array should be either a valid tick value (such as a number, date, datetime, or timeofday), or an object. If it’s an object, it should have a v property for the tick value, and an optional f property containing the literal string to be displayed as the label.

If true, the chart will start at the baseline and animate to its final state. Here, the solid portion of the candle within the buy-sell spread defines the open & close price, and the candle “wick” defines the maximum and minimum price range. To begin with, we need to establish the settings for the event markers in our graph. To get started, we need to add the Common UI module by including the following CDN link in the head section of our HTML page. Add() can be called with a single XOHLC object or with an array of such objects. In the below code, the user can change the title and behaviour of the Y-Axis according to requirements.

This JavaScript Chart demo shows you how to create a JavaScript Candlestick Chart or Stock Chart using SciChart.js. You can format the date labels on the XAxis by following the instructions on the Axis Label Formatting page. A CategoryAxis is necessary if you have Forex or Stock market data which includes weekend or overnight gaps, as this axis type measures by x-index, not by x-value. For CryptoCurrency data the DateTimeNumericAxis can be used as these are 24/7 markets.

Even within markets, price is defined somewhere between bid prices and asking prices. You can set risingColor or color to show the rising or falling price in different colors. Some other frequently used customizations include zoomEnabled, animationEnabled, etc. It can also be used as a zoom tool, as well as provides interactivity to the charts. Please note that using LightningChart JS for Trading use cases requires a special license agreement.For more information, please contact us.

Candlestick charts are widely used in technical analysis of price movement patterns. Candlestick charts are a fantastic data visualization tool for tracking the price movements of stocks over a period of time. In this tutorial, I’ll show you how to create your own candlestick chart using JavaScript. This example shows basic implementation of candlestick chart using OHLCSeries. This type of chart is used as a trading tool to visualize price movements. A candlestick figure can represent multiple recorded values, which are packed into 4 values (open, high, low and close).
