Mastercard Doing a 180. MAI called tops too early last time I looked at Mastercard. That's why you have stop losses.
It is a common feature I found when using Elliott, that there is frequently one subwave that is left unaccounted for, causing one to call pivot prematurily.
But calling pivot is never easy no matter, which tactic you use. Similarly, vWAP derived reversal to mean strategies often fail, as well as many of Jurik (and others -not singling anyone out) indicators that can be used for this purpose.
In my experience, it almost does not matter what you use, as long as you are the master of your system. Reading an indicator is easy, but reading what is between the lines is what creates real profit. Mechanical interpretation of squiggly lines does not lead to profits in the long run.
