Anatomy of a Candlestick
The first feature is known as the body and is the wide midsection of the candlestick that depicts the open and close during the observation period (most charts allow you to set the range for the candlesticks).
The close represents the top of the body in the green candlestick and the bottom of the body in the red candle.
The opposite is true of the open, which forms the bottom of the green candlestick and the top of the red candlestick.
4. High and Low
The last components, the high and low, are represented in the second feature of the candlestick referred to as the ‘wick’. Wicks are simply displayed as the thin lines extended above and below the body.
