OI Lottery Screener · how the report is assembledConceptual map
  1. 01Price, delta, OI filters
  2. 02Screen cheap OTM
  3. 03Contracts by ΔOI

Option price is the contract price; the entire premium is at risk.

Read the output

  1. 01Contracts with option price at or under a cap, |delta| at or under a cap, and oi_change_1d at or above a floor.
  2. 02Standing OI and session volume as context.
  3. 03Reader-tunable price, |delta|, ΔOI, OI, and DTE bounds (default DTE starts at 1).

Keep in mind

It is not the Unusual Options Activity volume/OI screen.

How to read it

From report to evidence

  1. 01

    Run the lottery screen

    Open OI Lottery Screener in Cookbooks. Tighten max price or |delta| if the board is too loud.

  2. 02

    Read ΔOI against price and delta

    A $0.15 8-delta call with +8,000 OI is the pattern. Volume/OI without cheapness belongs on the UOA recipe.

  3. 03

    Handoff to tape and OI path

    Option Trades and Pre-Move Positioning still do live prints and multi-session OI. This is one snapshot.

Method and limitations

A paid Cookbook that ranks cheap, far-OTM contracts with a large day-over-day OI increase. Deep-OTM is |delta|, not strike distance. It does not name a trader or promote lotto tickets. Official app template: OI Lottery Screener.

What the report computes

  • Contracts with option price at or under a cap, |delta| at or under a cap, and oi_change_1d at or above a floor.
  • Standing OI and session volume as context.
  • Reader-tunable price, |delta|, ΔOI, OI, and DTE bounds (default DTE starts at 1).

What it does not claim

  • It is not the Unusual Options Activity volume/OI screen.
  • ΔOI is not proof of a new speculative long, opening status, or a next-session pop.
  • It does not promote lottery trades. Product stance is validate, not sell lottos.

Deep-OTM is |delta| with a reader cap (default 0.2), not a raw strike-distance guess; option price is OptionChainTable.close, not underlying spot.

Frequently asked questions

Is this the same as the UOA screener?
No. UOA is volume versus standing OI (and relative volume). This screen is cheap + deep-OTM + ΔOI.
Does a big ΔOI mean someone opened a lotto?
Not from this report. Spreads, hedges, and closing prints can all add or look like added OI on a snapshot.
