Frequently Asked Questions

Is heavy put volume always bearish?

No. Can be bearish speculation, protective hedging, or premium selling. Without trade-side classification we cannot distinguish — spot action + skew change usually resolves it.

How is this different from high put/call ratio?

P/C ratio is total puts vs calls. This normalizes put volume against put OI specifically — isolating FRESH put-side flow rather than the side balance.

Does this help identify squeeze setups?

Indirectly. Persistent put buying on low-float names can precede short-squeeze dynamics, but the interpretation requires short-interest data alongside.

Why filter by put_oi?

Put Vol/OI computed when put OI is tiny produces noisy rankings. The 10,000 floor ensures we rank on chains with meaningful accumulated put positioning.
