On the smaller pull back right now it is allowed to do so, because it has not broken the major median line severely. So right now it can actually come down to 4180 or even 4170, but not lower than 4160.
On the smaller time frame such as M5 I see a triangular breakout. It is yet to be proven it is actually a triangle, and cant say so until further time passes by, but for now its thrust is behaving within the expectations of a uptrend scenario
