I concur with thatguy25. I am no expert, but have been trading using Luc's method since a few days before he deleted his old channel (and have net profit so far).
Your first circle is a clear base, which is never cracked. With Luc's method, there is no buy signal.
Your second base is cracked, and is quickly retested. Where it is retested is your new base. (Marked with an orange line in my edit).
Your two middle circles are "safe" buy zones, until they retest the previous base. Your last circle is NOT a safe buy zone, there is no clear base defining it.
