BANKNIFTY Watch for the premium differences

BANKNIFTY
yesterday we capped a near perfect expiry trading session in BANKNIFTY, despite choppiness it played well with our trend decider areas.
For today While we have opened in spot above trend decider, the futures continue to be within the previous day reference. We have to be mindful of the premiums.
From a immediate BNF levels point of view we are watching these two areas.
1. Long above 22780 areas for 22000 and higher
2. Pullback into below the trend decider (22590 ) for a move to 22350 and lower

Note: BNF lot sizes have increased to 25

What is a TREND DECIDER- That one price point or zone , where our view flips. Bullish above, bearish Below

Comment:

Absolutely brilliant pullback from the marked minor reference zone, nearly 400 points now.
important to see the play near 20300 areas
