The speaker whiteboards two very reliable chart patterns which are two of his favorites. The double top and double bottom repeat themselves due to human emotion. Traders need to see how the market reacts at the pivot point which represents the pivot which is between the two highs or two lows in both of these patterns.
For a double top, the distance between the high and the pivot point represents the amount that a stock is expected to head lower after it breaks below the pivot point. Conversely, for a double bottom, the stock is expected to move higher in the amount of the pivot point minus the double bottom once it breaks above the pivot.
