Frequently Asked Questions

What is the put/call ratio?

Put contract volume divided by call contract volume over the session. Above 1.0 = more put activity (hedging or bearish); below 0.7 = more call activity (bullish or speculative). Extreme readings can be contrarian at market-wide levels, but at the single-name level they typically reflect real directional positioning.

Why does the change matter more than the level?

The level is regime-dependent (some names always run high P/C because of chronic hedging demand). The day-over-day change isolates fresh flow — the moment positioning actually shifted, which is the signal informational traders react to.

Is this the same as unusual options activity?

Related but different. Unusual activity ranks by absolute volume; this screener ranks by directional shift. A name can have normal volume but a P/C ratio that flipped from 0.4 to 1.8 — that is a fresh hedging signal this screener would surface but unusual-activity would miss.
