There is evidence (which I will not get into all of them here) to suggest Feb was a top in NDX. One piece of evidence is the bigger Head and Shoulder structures at a top are usually a reversal pattern as bulls and bears fight it out. Multiple heads and shoulders (as seen in the chart) increase the likelihood that the bigger structure is valid and a top is in. Tops can never be known prior so there is still a lot of work that needs to be done.
I initially posted the H&S back on March 3rd. Since then, the structure has morphed into a bigger H&S and created another mini one within it.
