This next price cluster, in General Motors, comes from a coincidence of
three key price relationships between 30.00 and 30.08 (see Figure 6-29). You
may recognize this chart from the earlier chapter on retracements where
I illustrated the .236 retracement by itself. Even though some traders might
feel comfortable trading using a single price retracement, I think you would
prefer to know that there were at least two more overlapping price relationships
in that area!
