Thats just a TIP I post about.
With island reversal patterns, I've noticed many attempts to have a comeback. But most every fall from grace volume, equals the volume coming out of the island bottom channel when successful. So if you see a pop down at the bottom island and the volume doesn't match the strength falling in, it rarely comes all the way out, for a real comeback.
If you see 10 million shares volume in the fall down, you need to see 10 million shares possible on the way out.
