Japanese candlestick charts are similar to bar charts in that each ‘candle’ shows the opening price, closing price, high price and low price for the period. The candles are either green or red, depending on whether the closing price is higher than the opening price (green) or below it (red). The main body, or ‘wax’, represents the range between the opening and closing price and the ‘wicks’ show the highs and lows.
