A sharp correction of almost 47% doesn't look like wave 4 by any means like others are thinking.
An extended 5th wave is followed by a sharp correction.
Seems like corrective Wave A has been completed and a small pullback Wave B is expected towards 2000 odd levels before further fall towards 900 odd levels as Wave C to form a Zigzag.
I am just guesstimating a zigzag to support my current view, it can be any corrective pattern we will see later.
I have drawn a key level which is adding confluence for the price to find support.
Not a trade recommendation, do your own due diligence before taking any action.
