Just like a bar chart, a candlestick shows the market’s open, high, low, and close price for a period. But the candlestick has a wide rectangular part known as the body that represents the price range between the open and close of that day’s trading. And two shadows representing the highs and the lows. When the real body is filled in or is red, it means the close was lower than the open. If the real body is white/green, it means the close was higher than the open. Candlestick charts also depict the volume of a particular day. The width of the body keeps changing according to the volume.
