Overview

A Japanese candlestick chart is a combination of a line and bar chart used to describe price movements of an equity over time, where each bar represents the range of price movement over a given time interval. It is mostly used in technical analysis of equity and currency price patterns.

Candlesticks consist of the body (black or white) and an upper and a lower shadow (wick). The wick illustrates the highest and lowest traded prices of a stock, and the body represents the opening and closing trades. If the stock went up, the body is white, with the opening price at the bottom of the body and the closing price at the top. If the stock went down, the body is black, with the opening price at the top and the closing price at the bottom. It is not necessary for a candlestick to have either a body or a wick.

Some traders find candlestick charts easier to read than OHLC charts.

Japanese candlestick is a series type that is predominantly used for demonstrating the stock market data, due to its specifics. So AnyChart Japanese Candlestick series are also available in AnyStock - see the Japanese Candlestick series in AnyStock article to learn more.

This article explains how to create a basic Japanese Candlestick chart as as well as configure settings that are specific to the type. See the table below to get a brief overview of the Japanese Candlestick chart's characteristics:

Modules

The Japanese Candlestick chart requires adding the Core and Basic Cartesian modules:

<script src="https://cdn.anychart.com/releases/8.13.0/js/anychart-cartesian.min.js"></script>

Alternatively, you can use the Base module, which includes, among other things, the two modules mentioned above:

Quick Start

To create a Japanese Candlestick chart, use the anychart.candlestick() chart constructor. If you pass the data to this chart constructor, it creates a Candlestick series.

To create a Candlestick series explicitly, call the candlestick() method.

The following sample demonstrates how a basic single-series Japanese Candlestick chart is created:

// create data
var data = [
  [Date.UTC(2007, 07, 23), 23.55, 23.88, 23.38, 23.62],
  [Date.UTC(2007, 07, 24), 22.65, 23.7, 22.65, 23.36],
  [Date.UTC(2007, 07, 25), 22.75, 23.7, 22.69, 23.44],
  [Date.UTC(2007, 07, 26), 23.2, 23.39, 22.87, 22.92],
  [Date.UTC(2007, 07, 27), 23.98, 24.49, 23.47, 23.49],
  [Date.UTC(2007, 07, 30), 23.55, 23.88, 23.38, 23.62],
  [Date.UTC(2007, 07, 31), 23.88, 23.93, 23.24, 23.25],
  [Date.UTC(2007, 08, 01), 23.17, 23.4, 22.85, 23.25],
  [Date.UTC(2007, 08, 02), 22.65, 23.7, 22.65, 23.36],
  [Date.UTC(2007, 08, 03), 23.2, 23.39, 22.87, 22.92],
  [Date.UTC(2007, 08, 06), 23.03, 23.15, 22.44, 22.97],
  [Date.UTC(2007, 08, 07), 22.75, 23.7, 22.69, 23.44]
];

// create a chart
chart = anychart.candlestick();

// create a japanese candlestick series and set the data
var series = chart.candlestick(data);

// set the container id
chart.container("container");

// initiate drawing the chart
chart.draw();

General Settings

In AnyChart there are many settings that are configured in the same way for all chart types, including the Area chart (for example, legend and interactivity settings).

Read the overview of general settings: General Settings.

Special Settings

Appearance

The appearance settings of a Japanese Candlestick series can be configured in three states: normal, hover, and selected. Use the normal(), hovered(), and selected() methods.

Combine them with the following methods to adjust falling and rising candlesticks:

• fallingFill() and risingFill() to set the fill
• fallingHatchFill() and risingHatchFill() to set the hatch fill
• fallingStroke() and risingStroke()to set the stroke

Also, you can use some other methods from anychart.core.StateSettings.

In the sample below, there are two Japanese Candlestick series with appearance settings configured:

// configure the visual settings of the first series
series1.normal().fallingFill("#00cc99", 0.3);
series1.normal().fallingStroke("#00cc99", 1, "10 5", "round");
series1.hovered().fallingFill("#00cc99", 0.1);
series1.hovered().fallingStroke("#00cc99", 2, "10 5", "round");
series1.selected().fallingFill("#00cc99", 0.5);
series1.selected().fallingStroke("#00cc99", 4, "10 5", "round");

series1.normal().risingFill("#0066cc", 0.3);
series1.normal().risingStroke("#0066cc");
series1.hovered().risingFill("#0066cc", 0.1);
series1.hovered().risingStroke("#0066cc", 2);
series1.selected().risingFill("#0066cc", 0.5);
series1.selected().risingStroke("#0066cc", 4);


// configure the visual settings of the second series
series2.normal().fallingFill("#00cc99", 0.3);
series2.normal().fallingHatchFill("forward-diagonal", "#00cc99");
series2.normal().fallingStroke("#00cc99", 1, "10 5", "round");
series2.hovered().fallingFill("#00cc99", 0.1);
series2.hovered().fallingHatchFill("forward-diagonal", "#00cc99");
series2.hovered().fallingStroke("#00cc99", 2, "10 5", "round");
series2.selected().fallingFill("#00cc99", 0.5);
series2.selected().fallingStroke("#00cc99", 4, "10 5", "round");
series2.selected().fallingHatchFill("forward-diagonal", "#00cc99");

series2.normal().risingFill("#0066cc", 0.3);
series2.normal().risingHatchFill("forward-diagonal", "#0066cc");
series2.normal().risingStroke("#0066cc");
series2.hovered().risingFill("#0066cc", 0.1);
series2.hovered().risingHatchFill("forward-diagonal", "#0066cc");
series2.hovered().risingStroke("#0066cc", 2);
series2.selected().risingFill("#0066cc", 0.5);
series2.selected().risingStroke("#0066cc", 4);
series2.selected().risingHatchFill("forward-diagonal", "#0066cc");

Point Size

This chart type allows you to set the size of its points. Read more in the Point Size article.

Labels

Labels are text or image elements that can be placed anywhere on any chart (they can be enabled on a whole series or for a single point). For text labels, font settings and text formatters are available.

Tooltips

A Tooltip is a text box displayed when a point on a chart is hovered over. There is a number of visual and other settings available: for example, you can edit the text by using font settings and text formatters, change the style of background, adjust the position of a tooltip, and so on.

Candlestick Patterns

In technical analysis, a candlestick pattern is a movement in prices shown graphically on a candlestick chart. Some believe that it can predict a particular market movement. The recognition of the pattern is subjective, and charting programs have to rely on predefined rules to match the pattern. There are 42 recognized patterns, which can be divided into two groups: simple and complex.

Here are the most popular simple patterns, shown in the sample below:
