BANKNIFTY is showing 5 waves down from the top. Considering this as an impulse move, the current upward structure can only be corrective. This may retrace 50-61.8% fibonacci level where it could reverse with a sharp decline. Currently, an invalidation level can only be considered at the 46,300 top, i.e start of wave 1.
This idea is based on the Elliott Wave Theory. Manage your own risk while investing/Trading.
