      Once a pattern is revealed, the next step is to confirm the pattern.With all technical indicators, volume is one of the best confirmations.With any sharp price movement, if volume does not increase, it is usuallyan indication of a "weak" breakout, and one that should be approached withcaution. For sideways trends, any variance in the average daily volume overa period of days can often be a revealing indication of an upcoming changein pattern. It is important to remember, however, that even volume as aconfirming indicator of price movement is never 100-percent accurate.
