A candlestick chart is a type of price chart widely used by technical analysts. Candlesticks capture the same price information as a bar chart: the open, high, low and close. A thick box (known as the body of the candle) joins the open and close values. Thin lines on either end of the body (known as shadows) join the high and low prices. If the open value is higher than the close value, the body of the candle is solid or colored. Conversely, if the close is higher than the open then the body of the candle is clear, white or unshaded.
