Are you really calling that thing that happened at the end of July a normal thing? To me it was fear at its finest. The price broke out and acted like it was about to establish a higher low and then when it corrected it didn't go half the way. It went far below the point from where it started to rise which means that people oversold. Not onl;y those who bought into that rise sold but also those who were holding at the downtrend, before it even broke out to the upside.
