This doesn't say that but normally, the most recent setup began from 42500 and the one before that is 41K.
so simple PA says that this should act as support zones.
1000pt in BN is 2.5%, which is actually nothing.
42500 decisively gone. now 41800. but 41k is nearest TDST support.
Nifty is bit steeper TDST support 17k, but maybe some sideways instead and not necessarily hit it in this expiry week.
Both are setup bars #7.
so until bar #8/9 ie. Mon-tue, we need to see what range is formed by them. These are crucial days, even though rally/bull flips can occur but currently all news are headwinds.
