Interesting read, I will admit some of it was confusing to me, still got a lot to learn. (and how to spell, form should be from on the retrace from the A/D leg)
Looking at TVIX again I determined that the fib retrace of .382 was a crab pattern which has a final D point at 161.8 extension from the X/A leg. Very interesting outcome and target for profit.
So where does that leave us now? The deeper retrace at point B sets up a possible Butterfly pattern, and the final D point is similar to the crab pattern with a 1.618 extension from the X/A leg and also has a fib .382 retrace of the A/D leg for a profit target. Which also lines up with the last structure support/resistance at 19.38
