However, there have been instances where the fib levels of the cd line will act as resistance. Take a look at the example below.
It is up to your trading plan to determine where you are entering your trade. A word of advice from Mr. Wolfe is to enter somewhere in between point 5 and the 2-4 line attached to point 3. He calls this the "sweet spot." I'm sure he has a more accurate way of entering his trades but I have never taken his course so I cannot comment on how you should trade this pattern.
I hope this answers your question.
