For Wednesday
Banknifty level 22550 ,22650 and 22750 means 22550 to 22750 resistance zone but banknifty so many time test so not strong.
Above 22550 buy side upto 22600 and 22630
Above 22650 buy side upto 22700 and 22730
Above 22750 you can go long if sustain then 23000 also possible
Down side 22550 and 22350 both act as a support
