Candle Stick Chart

  • 6 minutes to read

Short Description

The Candle Stick Chart is represented by the CandleStickSeriesView object, which belongs to Financial Series Views (also called Low-High-Open-Close).

This view is used to show the variation in the price of stock over the course of a day. Each point consists of a rectangle (body the bottom and top values of which correspond to the Open and Close prices) and a vertical line (shadow, wick or tail the bottom and top values of which correspond to the Low and High prices). If the stock closes higher than its opening price, the body is hollow. And if the stock closes lower than its opening price, the body is filled.

For Candle Stick charts, you can choose for which price level (Low, High, Open or Close) to enable FinancialSeriesViewBase.ReductionOptions, meaning that in case the specified price is lower in comparison to the previous point’s value, the subsequent point is painted red (or any other color).

A Candle Stick chart is shown in the image below. Note that this chart type is based upon XYDiagram, so it can be rotated to show bars either vertically or horizontally.
