Open-high-low-close chart

An open-high-low-close chart (OHLC) is a type of chart typically used in technical analysis to illustrate movements in the price of a financial instrument over time. Each vertical line on the chart shows the price range over one unit of time, e.g., one day or one hour. Tick marks project from each side of the line indicating the opening price on the left, and the closing price for that time period on the right. The bars may be shown in different hues depending on whether prices rose or fell in that period.
