The typical stock chart is represented with ticker data in a candlestick chart which is used for the technical analysis of the price ranges. A candlestick chart compares the high and low prices of a day to the open and close of the ticker symbol.
- The body of the candlestick chart shows the open and close trade values (O/C).
- The wicks of the candlestick chart show the high and low trade prices (H/L).
- The distance between the top and bottom of the ticker value is the day range of the ticker price.
- The candlestick chart ticker value is hollow when the asset closed higher than it opened.
- The candlestick chart ticker value is filled when the asset closed lower than it opened.
- A black or red candle represents a price with a lower closing price than the prior candle's close.
- A white or green candle represents a higher closing price than the prior candle's close.

Web Components Chart Annotations
The Crosshair Annotation Layer provides crossing lines that meet at the actual value of every targeted series. Crosshair types include: Horizontal, Vertical, and Both. The Crosshairs can also be configured to snap to data points by setting the
crosshairsSnapToData property to true, otherwise the crosshairs will be interpolated between data points. Annotations can also be enabled to display the crosshair's value along the axis.
The Final Value Layer provides a quick view along the axis of the ending value displayed in a series.
The Callout Layer displays a callout at X/Y positions.
Note: When using the ordinal X axis mode, the CalloutsXMemberPath should point to the numeric index of the item, otherwise CalloutsXMemberPath should point to the time value.
Web Components Chart Panes
The following panes are available:
- Price Pane - Renders prices using Line, Candlestick, Bar (OHLC), trendlines and financial overlays.
- Indicator Pane - Renders all the financial indicators in a separate chart while the BollingerBands and PriceChannel overlays are rendered in the Price Pane because they share the same values range on Y-Axis.
- Volume Pane - Renders stocks volumes using Column, Line, and Area chart types below all above panes.
- Zoom Pane - Controls the zoom of all the panes and it is always rendered at bottom of the chart.
Financial Indicators are often used by traders to measure changes and to show trends in stock prices. These indicators are usually displayed below the price pane because they do not share the same Y-Axis scale.
By default the indicator panes are not displayed. The toolbar allows the end user to select which indicator to display at run time.
In order to display an indicator pane initially, the
indicatorTypes property must be set to a least one type of indicator, as demonstrated in the following code:
The volume pane represents the number of shares traded during a given period. Low volume would indicate little interest, while high volume would indicate high interest with a lot of trades. This can be displayed using column, line or area chart types. The toolbar allows the end user to display the volume pane by selecting a chart type to render the data at runtime. In order the display the pane, a volume type must be set, as demonstrated in the following code:
This pane displays stock prices and shows the stock's high, low, open and close prices over time. In addition it can display trend lines and overlays. Your end user can choose different chart types from the toolbar. By default, the chart type is set to
Auto. You can override the default setting, as demonstrated in the following code:
Note that is recommended to use line chart type if plotting multiple data sources or if plotting data source with a lot of data points.
This pane controls the zoom of all the displayed panes. This pane is displayed by default. It can be turned off by setting the
none as demonstrated in the following code:
Note that you should set the
zoomSliderType option to the same value as the

In this example, the stock chart is plotting revenue for United States.
