Put/Call Ratio Deviation Screener · how the report is assembledConceptual map
  1. 01Name’s prior sessions
  2. 02Call / put vs baseline
  3. 03Mix deviation

This uses call ÷ put contracts, despite the official title.

Read the output

  1. 01Session call contracts ÷ put contracts (tape size, not OI).
  2. 02That name’s average daily ratio on sessions strictly before the represented date.
  3. 03Deviation = today ÷ baseline − 1, labeled call-heavy / put-heavy / in line.

Keep in mind

It is not the UOA volume/OI screen and not the OI lottery screen.

How to read it

From report to evidence

  1. 01

    Run the mix screen

    Open Put/Call Ratio Deviation Screener in Cookbooks. Tighten min |deviation| if the board is noisy.

  2. 02

    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.

  3. 03

    Handoff to UOA or tape if you act

    Unusual mix plus unusual volume/OI is two facts. This recipe only has the mix.

Method and limitations

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. Official app template: Put/Call Ratio Deviation Screener.

What the report 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.

Deviation is today (call size ÷ put size) divided by that symbol’s own average daily ratio on prior sessions, minus one — not versus a market-wide 1.0.

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.
