Candlestick Components

The candlestick has a wide part, which is called the "real body", and a narrow line called the "shadow":

1. The body represents the price range between the open and close of that day's trading. 
2. When the real body is filled, black, or green it means the close was lower than the open. If the real body is empty, or red it means the close was higher than the open.
3. The shadows show the high & low prices of that day's trading.
