Compared to traditional bar charts, many traders consider candlestick charts more visually appealing and easier to interpret. Each candlestick provides a simple, visually appealing picture of price action; a trader can instantly compare the relationship between the open and close as well as the high and low.

Hollow candlesticks, where the close is greater than the open, indicate buying pressure. Filled candlesticks, where the close is less than the open, indicate selling pressure
