Candlestick Chart
A candlestick is a visual representation of price movement during a given period. A candlestick chart is a group of candlesticks in chronological order. A candlestick has two parts, the "body" and the "tails". If the body is filled in (blue), the stock price has gone down during that time period, whereby the top of body is the open price and the bottom of the body is the close. If the body is not filled in (white), the stock price has gone up during that time period, whereby the bottom of the body is the open and the top of the body is the close. If the stock price did not change, a horizontal line will represent the body. The "tails", or vertical lines, extending from the body indicate the high and low prices during that time period.
