Real Body and Upper and Lower Shadows

The rectangular area between the opening and the close of a session of trading is called the real body. The thin lines that look like candle wicks above and below the real body are called shadows. The shadow above the real body is called the upper shadow, the top end of the upper shadow corresponding to the high of the session of trading, and the shadow below the real body is called the lower shadow, where the bottom end of the lower shadow corresponds to the low of the session of trading.
