The third pattern in the price pattern series is the eight-bar open/close moving average pattern. It is a simple pattern that is based on the relationship between the opening and closing price of a price bar. Typically, market lows are preceded by a period of accumulation while market highs are often preceded by a period of distribution. One way to determine pending price tops or bottoms is to monitor the relationship between the opening and closing price of a market over a given period of time. If the close of a given price bar is higher than the open of a given price bar for a given period of time, then a low is likely. If the close of a given price bar is lower than the open of a given price bar a given period of time, then a high is likely. This chapter demonstrates a simple method for determining and taking advantage of short-term trend changes using the eight open/close pattern.
