Some corrections go for a third or even a fourth leg, so I prefer a different labeling system to account for this and discuss it later in the books. In its simplest form, it counts the legs of a pullback. For example, if there is a down leg in a bull trend or in a trading range and a bar then goes above the high of the prior bar, this breakout is a high 1. If the market then has a second leg down and then a bar goes above the high of a prior bar, the breakout bar is a high 2. A third occurrence is a high 3, and a fourth is a high 4. In a bear leg or in a trading range, if the market reverses back down after one leg, the entry is a low 1. If it reverses back down after two legs up, the entry is a low 2 entry and the bar before it is a low 2 setup or signal.
Since measured moves are an important part of trading and the AB = CD terminology is inconsistent with the more commonly used ABC labeling, the AB = CD terminology should not be used. Also, I prefer to count legs and therefore prefer numbers, so I will refer to each move as a leg, such as leg 1 or the first push, and then leg 2, and so forth. After the chapter on bar counting in the second book, I will also use the high/low 1, 2, 3, 4 labeling because it is useful for traders.
