Let's take the case on the far right of the figure (“Setup 2”). In the rise from I to H, there is no knot of support. The uphill move is fast and long.

The way to trade this is to split the move in half and place an order to close out the trade there. In this example, midway up the run from I to H is J. Place an order to cover a short at J. After the double top FG confirms when price closes below H, price drops to K before beginning a pullback.

Figure 1.8 Shown are three ways to trade a pullback.

You don't see this setup often because there is usually a knot along the uphill run from I to H, but it does happen. Take advantage of it and expect the stock to find support midway in the I to H run like it does here at J.

If the run does show a knot but it looks too far below the chart pattern, then split the run in half like I've explained. In technical terms, if support is too far away, then price will reverse closer to the chart pattern. What is closer? Most pullbacks bottom in the 7% to 8% range. If a knot is 10% or 15% away, then that's too far unless there's a fundamental reason to drive price down hard and fast (bad earnings, bad future outlook, that kind of thing).

If the move from I to H is exceptionally long, you might want to split the run into thirds and place a trading order a third of the way down to I from H. Search for other stocks showing the same pattern and see where they turn. The Patternz simulator can make the search easy.
