A CandleVolume candlestick consists of five components: open, high, low, close and volume. As with normal candlesticks, the open and close form the body of the candlestick, while the high and low form the upper and lower shadows. Volume determines the width of the candlestick. Wide candlesticks form when volume is high, while narrow candlesticks form when volume is low. The example below shows basic black and white candlesticks based on CandleVolume. Wide and hollow candlesticks form when the close is well above the open and volume is high. Wide and filled candlesticks form when the close is well below the open and volume is high. Narrow candlesticks form when volume is relatively low.
