Sushi Roll

No, this one doesn't have anything to do with raw fish. Or even rice, or food, or Japan, or Asia. It has to do with technical analysis.

The term applies to a certain pattern that occurs in technical analysis. It involves 10 candlebars (charts representing distinct periods of time...usually a trading session). The first five have a narrow range: highs and lows pretty close together. The next five have a wider range (higher highs and lower lows) than the first group.

Taken as a whole, the pattern suggests some change is coming. Like when animals start acting funny before an earthquake, or how waves get bigger before a storm rolls in.

The "sushi roll" name comes from the fact that the first group of candlesticks (known as the inside bars) get wrapped up by the second set (known as the outside bars). So the inside is wrapped up in the outside...like the fish in a tuna roll.
