Definition of 'Sushi Roll'
A candlestick pattern consisting of 10 bars where the first five (inside bars) are confined within a narrow range of highs and lows and the second five (outside bars) engulf the first with both a higher high and lower low. If a sushi roll appears in a prevailing trend, it is a sign that there may be an upcoming trend reversal.
