"Mark Fishers Sushi Roll Reversal "
Never heard of that one.
He defines it as a period 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. (The pattern is similar to a bearish or bullish engulfing pattern except that instead of a pattern of two single bars, it is composed of multiple bars.) In his example, Fisher uses 10-minute bars.
When the sushi roll pattern shows up in a downtrend, it warns of a possible trend reversal, showing that it’s a good time to look to buy or at the very least, exit a short position. If it occurs during an uptrend, the trader gets ready to sell. While Fisher discusses five-bar patterns, the number or duration of bars is not set in stone. The trick is to identify a pattern consisting of the number of both inside and outside bars that are the best fit with the chosen stock or commodity using a time frame that matches the overall desired time in the trade.
