This is a volume Candle indicator. Volume Candlestick charts are created in the traditional way using open, high, low, and close data but with the addition of a volume component that determines the width of the candlestick. The greater the volume, the wider the candlestick. The colors in the Volume chart also have meaning. A green volume bar means the stock closed higher on that day versus the previous day's close. A red volume bar means the stock closed lower on that day than the previous day's close.
