Box plot chart (stock)

A box plot chart shows the price changes over time for stocks, bonds, currencies, commodities, and other types of financial instruments. Each bar corresponds to a time unit, for example, one day, hour, or minute. This chart type is frequently used in the technical analysis of financial market trends.

Box plot charts are similar to candlestick charts. The difference is that in addition to the open, close, low, and high values, you can also specify the median value.

The following table lists the main elements of the box plot.

Image	Item	Explanation
	Body	The region between the opening and closing prices (see below) for the time unit represented. The color of the body depends on whether the closing price is higher or lower than the opening price (the colors depend on the color palette used). In this example, the closing price is higher than the opening price.
	Open	The price at the beginning of the time unit represented.
	Close	The price at the end of the time unit represented.
	Mid	The median price traded in the time unit represented. That is the price in the middle of the whole list of prices (sorted in ascending or descending order) traded in the time unit represented or the average of the two middle prices (if there is an even number of data points).
	Low	The lowest price traded in the time unit represented.
	High	The highest price traded in the time unit represented.

When to use

Box plot charts can help you detect, predict, and monitor the trends of the stock prices, assisting you in the stock buying or selling decisions.
