Run the put/call ratio deviation recipe
A paid Cookbook that compares each single name’s session call/put contract ratio to that same name’s average daily ratio on prior sessions. Names without enough history are omitted, not padded.

The job
See whose call/put mix shifted versus its own tape, not versus a market-wide 1.0 rule of thumb.
What this recipe computes
- Session call contracts ÷ put contracts (tape size, not OI).
- That name’s average daily ratio on sessions strictly before the represented date.
- Deviation = today ÷ baseline − 1, labeled call-heavy / put-heavy / in line.
What it does not claim
- It is not the UOA volume/OI screen and not the OI lottery screen.
- A high ratio is not “bullish” unless it is high versus that name’s own history.
- Mix is not opening status, a trader identity, or a forecast.
How to read it
Step 1
Run the mix screen
Open Put/Call Ratio Deviation Screener in Cookbooks. Tighten min |deviation| if the board is noisy.
Step 2
Read today versus baseline, not the raw ratio
A 3.0 ratio is ordinary if that name usually prints 2.8. The deviation column is the job.
Step 3
Handoff to UOA or tape if you act
Unusual mix plus unusual volume/OI is two facts. This recipe only has the mix.
Frequently asked questions
- Is a high call/put ratio a buy signal?
- No. This screen only flags a mix that is far from that name’s own baseline. It does not say the next session goes up.
- Why was a name omitted?
- Not enough completed sessions in the baseline window, or put volume was zero (ratio undefined). That is unavailable, not a 1.0.

- Put/call ratioPut/call ratio compares put activity to call activity by contracts, volume, or premium. Context decides whether heavy puts mean hedges or bearish bets.
- Option flowOption flow is the time-and-sales stream of options prints: contract, size, premium, and inferred aggressor side.
- Unusual options activity (UOA)UOA flags contracts or underlyings trading far above recent norms in volume, size, or premium. It is an attention screen, not a directional signal.

- Options Flow for Swing TradersSwing traders care about positioning that can last more than a day: unusual flow, OI confirmation, and walls for multi-day levels.
