Candle Size

A candlestick chart (also called Japanese candlestick chart) is a style of financial chart used to describe price movements of a security, derivative, or currency.

It is similar to a bar chart in that each candlestick represents all four important pieces of information for that day: open and close in the thick body; 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.
