Strike 24,000 PE vs 24,300 CE: what the open-interest shift is (and isn't) telling us
Sharing my read of today's option chain (sample data).
During the afternoon slide, put writers added heavily at 24,000 while call writers rolled down from 24,500 to 24,300. The put-call ratio moved from roughly 0.7 to 0.9.
| Strike | Call OI chg | Put OI chg |
|---|---|---|
| 24,300 | +32.8 L | −12.1 L |
| 24,100 | −4.2 L | +24.5 L |
| 24,000 | −16.9 L | +48.2 L |
My takeaway: the market is pricing a 24,000–24,300 range into expiry. OI is not a crystal ball though, writers get trapped too.
Questions for the room:
- Are writers at 24,000 hedged with futures, or naked?
- How much weight do you give OI versus price action?
Not investment advice. I hold no positions.

Good read. I'd add that the 24,000 put base coincides with the 50-day average, so writers have a technical reason to defend it.
Agreed. If 24,000 breaks on a closing basis, I expect those writers to cover fast.
That's the risk with crowded strikes — the unwind can accelerate the move.

Counterpoint: a lot of that put OI is likely hedged with futures shorts. I wouldn't read it as pure bullishness.
Fair. Without participant-wise data we are guessing at the hedge ratio.

Saving this. The table format is really helpful for beginners like me.
