5d
NIFTY 23600 PE
Nifty closed at 23,649.95, leaving 23,600 as the nearest defended put shelf. If spot slips below it and holds, the floor weakens and writers will lose the clean range argument.
5d
NIFTY 23700 CE
Nifty stayed below 23,700 after closing at 23,649.95, keeping the strike as the first call-writer ceiling. A close above 23,700 will challenge the range and pull attention to 23,800.
5d
BANKNIFTY 53500 PE
BankNifty closed at 53,537.00, making 53,500 the immediate put-writer trench. A sustained break below 53,500 will turn the floor from support into supply pressure.
5d
BANKNIFTY 54000 CE
BankNifty remained below 54,000 after closing at 53,537.00, so call writers still own the nearby ceiling. A close above 54,000 will weaken that control and reset the chain higher.
