Black Candlestick
A Black Candle represents the open, high, low and closing points on a candlestick chart for a time period where the opening price is above the closing price. At the top and bottom of the candle are wicks which are also sometimes called shadows.

A black candle is the same as a red candle. Some candlestick charts show the up candles as green candles and the down candles as red candles.
