Bar Chart

A price chart that depicts each trading period (minute, hour, day, week, month, etc.) as a vertical line (“bar”) ranging from the low price to the high price.  Most bar charts also include two small hash marks on either side of the bar: one on the left that denotes the opening price and one on the right that denotes the closing price.

Below is an example of a bar chart featuring the PowerShares QQQ Trust ETF.
