TRANSPARENCY & UPDATES

Transparency and updates log: what we corrected and why

Market numbers change, and we can get a number or its description wrong. When that happens, we don't erase it quietly. We write here what it said, what it says now, and why, with the date. Each entry takes you to the page so you can check it yourself.

Last updated: Oct 7, 2026 · 8 entries, 6 of them corrections

  1. Correction

    Gamma regime and next-day move size: the result after comparing each stock with itself

    BeforeNext-day range above the Gamma Flip 3.1% and below it 2.6%, the "opposite of what you'd expect".
    NowThat comparison mixed calm stocks with volatile ones. Comparing each stock with itself shows no real difference: the move is neither calmer nor wider.

  2. Methodology

    We published a study on options walls from our archive

    What's newWe compared how walls hold against a random line at the same distance. Result: both held about the same, so distance is what explains the hold. The numbers update after every session.

  3. Definition

    We rewrote the definitions of the Call Wall and Put Wall

    BeforeA ceiling that caps the rise, and a floor that gets defended.
    NowWhere market makers' hedging is concentrated now: a map of positioning, not a barrier that stops price. And next to every hold rate on the platform, the random line's rate now shows too.

  4. Correction

    The "What we declined to show" page carried a result that did not hold up over time

    BeforeThe Put Wall held 71.3% versus 65.7% for a fake level, over only 12 days.
    NowThe number now comes from the test rerun after every session. Over 57 sessions, the wall and the random line came out about equal, and the sentence updates itself if the result changes.

  5. Correction

    The track record description promised a longer period than its data covered

    Before"Over 24 months" in the page description.
    NowThe period is written from the dates of the first and last trade in the same table, so it never claims more than it shows.

  6. Correction

    The wall hold rate was measuring mid-session levels

    BeforeA published rate (88%) said to be for end-of-session levels, which was taking the last snapshot at noon because of a timing bug.
    NowThe last snapshot is truly taken inside the session on New York time, and the hold rate is shown by the wall's distance from price, not as a single number.

  7. Correction

    The 10-year Treasury yield showed two different numbers on two pages

    What it used to show4.63% on one page and 4.69% on another on the same day, because each page fetched it separately.
    NowOne source calculates the number for every page, so one concept never shows two numbers.

  8. Correction

    Fixed prices that showed in the ticker when the live feed was down

    BeforeNine hard-coded prices, one of them 40% away from the market.
    NowThe ticker shows only what it actually receives, and an automatic check blocks any hard-coded price from coming back.

How do we handle mistakes?

  • We correct it on the page itself and then add the entry here the same day.
  • We never delete an entry from the log, even when the mistake is old.
  • Each number is calculated from one source on every page, so one thing never shows two numbers.
