Candlestick chart

A candlestick chart (also called Japanese candlestick chart or K-line) is a style of financial chart used to describe price movements of a security, derivative, or currency. While similar in appearance to a bar chart, each "candle" represents four important pieces of information for that day: open and close in the thick body, and high and low in the "candle wick". Being densely packed with information, it tends to represent trading patterns over short periods of time, often a few days or a few trading sessions. Candlestick charts are most often used in technical analysis of equity and currency price patterns. They are used by traders to determine possible price movement based on past patterns, and who use the opening price, closing price, high and low of that time period. They are visually similar to box plots, though box plots show different information.
