Wave C is usually 100% – 161.8% x Wave A in size, but it is possible that it becomes as big as 261.8% on rare occasions.
What I feel is banknifty is making a zigzag with C extended.
The further down may be till 2.618x and the level is 34800(PRZ).
This is not a trade advise but we can observe the case.
Thank you.
