Bar Chart

A method of displaying the open, high, low and close prices for a financial instrument for a specific period. Bar charts use single, vertical bars to illustrate a stock's price range and opening/closing prices for a designated time period. The bars may illustrate daily, weekly, or monthly periods. For example on a weekly chart, each bar represents one week and on a daily chart, each bar represents one day. The top of the bar indicates the stock's highest price of the period. The bottom of the bar represents the stock's lowest price for that period. The small perpendicular bar on the left designates the stock's opening price. The one on the right shows the stock's closing price.
