Common questions about NDXP
What does the options flow on NDXP actually mean?
It is the money that changed hands in NDXP options on 2026-10-16: $106.0M paid for calls, $1.0B for puts. Premium is the better read than contract count, because a thousand cheap far-dated calls and one large near-dated block are not the same conviction, and only premium tells them apart.
Is heavy call buying in NDXP bullish?
Not by itself. 10% of NDXP's premium sat on the call side, and a good share of any day's call volume is someone hedging a short, closing a position, or a market maker managing inventory. Flow says where money went, never why. It is one input among several, which is how it is weighted on the desk.
What is the difference between volume and open interest on NDXP?
Volume is what traded today: 44651 calls and 64029 puts. Open interest is what is still on the book afterwards. Volume can spike and vanish the same day; open interest rising means positions were opened rather than closed.
