OHLC Bar Chart visually presents the data series as a sequence of bars.

Each OHLC bar is a vertical line connecting the High and the Low price points (ticks), and graphically represents the range of an instrument's price movement over a defined interval. The price of the first tick of the group, on which the bar is based, is indicated on the left side of the line by a mark known as the bar's Open component. The price of the last tick of the group, on which the bar is based, is indicated on the right side of the line by a mark known as the bar's Close component.

An OHLC Bar has three components: Open, High/Low, and Close.

The color and width of each of the bar's components can be customized in the Chart Style section.
