Makes a great gift

Use the measure rule to predict a price target. The rule varies from chart pattern to pattern as the below table shows. Usually the measure rule is the height added to (upward breakouts) or subtracted from (downward breakouts) the breakout price (this is the method I describe in my book, Encyclopedia of Chart Patterns, Second Edition).

Unfortunately, that formula doesn’t work well. Instead, multiply the height by the “percentage meeting price target,” which I show in the below table as percentages. The result should be a closer and more accurate price target.

For example, if a broadening top has a high price of 25 and a low of 20 with a breakout of 22, an upward breakout target in a bull market would be B + ((H - L) * 62%) = 22 + ((25 – 20) * 62%) = $ 25.10. A downward breakout in a bull market would use the formula B - ((H - L) * 37%) = 22 – ((25 – 20) * 37%) = $ 20.15.

The formula may look complex but it’s not. Anyone with a doctorate in mathematics can figure it out in a few hours.

Notes:

B = The breakout price which is where price pierces a trendline.

CBG = The closing price before a gap.

CPH = The highest price in the corrective phase.

CPL = The lowest price in the corrective phase.

H = Price of the highest peak in the chart pattern

L = Price of the lowest valley in the chart pattern

H – L is the price of the highest peak minus the price of the lowest valley.

HL = Lowest price in the head.

HH = Highest price in the head.

NL = Neckline, measured vertically from the peak or valley in the head.

RL = Price of the right saucer lip.
