What the columns mean6 groups · 10 columns

Report’s part: The report’s own share of what the options priced the day before, taken from two or more expiries.; ColumnsPriced
Realized: C2C is the previous close to the next close; By 10:00, the 09:55–10:05 ET average price against the previous close, never substituted from the open when it is missing.; ColumnsC2CBy 10:00
Chart: The grey band is what the options priced and the marks are what happened, on a ±25% scale.; ColumnsPriced · realized · ±25%
Crush: How far implied volatility fell in the report’s expiry. ATM is at the strike nearest the price, day before to day after at 15:46, read late in the session, so it does not compare with a figure read at the open. As-sold is at the strike a position was already holding; a blank there is not a small crush, because after a big move that strike is often no longer quoted the day after. Open is backed out of the option’s own 10:00 price the next morning.; ColumnsATMAs-soldOpen
Forecast: Pred. is the crush we wrote the day before the report and never changed, marked rec where it was rebuilt from history. Error is what happened minus the forecast, graded against the collapse at the new strike, in points of the crush.; ColumnsPred.Error
Sold: P&L: sold at the bid the day before and bought back at the 10:00 ask, as a share of the premium collected. A record of what happened, not a recommendation.; ColumnsP&L

The stock closed past the priced move on 2 of 7 reports, and was past it at 10:00 the next morning on 2 of 7. It held 80% or more of its 10:00 move into the close on 6 of 7. Sold P&L, locked here, is what selling the straddle kept at each report. It opens with a free account. A record of what happened, not a recommendation. A dash is a number we do not have, not a zero.

SNDK · data quality on this name · every marker, countedSNDK · data quality on this name

We publish flagged reports instead of dropping them. A marker on one report says little about the company and one on most of them says a lot, so the count is what tells them apart.

Every marker on this name, counted against the report it touched, newest first as in the history above. The first column is the current reading.

What each marker means10 markers

macro event in the window A scheduled macro event (a CPI print, an FOMC day) falls inside the decomposition window, so a little of the volatility attributed to the event belongs to the calendar instead.Affects Implied (event)

held to expiry The straddle that was sold expired at one of these closes, so its price there is its settlement value: the distance from the stock to the strike. That exit pays no bid/ask spread, and it ignores the cost of being assigned stock on the in-the-money leg.Affects Short-straddle P&L

crush expiry substituted The expiry that would have been measured was not available on both sides of the print, so a neighbouring one stood in. The crush is real; it is measured on a slightly different contract than the label implies.Affects Crush (re-struck)

thin trade at the cover Too few prints stand behind the 10:00 anchor for it to be a reliable price. The crush is shown and kept out of the rankings.Affects Crush at 10:00

derived numbers unreliable Quotes on this name were too wide — or a 25Δ wing was missing — for the derived numbers on this row to be trusted: implied move, decomposition, crush and skew. Shown, kept off the board’s sort, and marked ≈ where its rank is shown.Affects The derived columns

30-day IV extrapolated No pair of listed expiries brackets 30 days, so the 30-day volatility was extrapolated more than a week past the nearest one rather than interpolated. A shorter reach is not flagged: it moves the number by well under one volatility point.Affects Crush (30-day) · IV rank

an anchor was refused At least one observation behind the 10:00 crush was rejected: a price below intrinsic, a crossed quote, or a solve that did not converge. The number here was measured from the anchors that did invert, and is scored normally.Affects Crush at 10:00

gapped past the wings The stock gapped far enough that the contract sold at T−1 is no longer near the money at the cover, so the as-sold crush there is partly a move along the smile rather than a collapse in volatility.Affects Crush at 10:00 (as sold)

next-morning price from quotes The option at the 10:00 strike did not trade on both sides between 09:55 and 10:05, so the next-morning volatility was read from the midpoint of its quoted bid and ask over the same ten minutes. Used only when both sides were quoted and the quote was less than 50% wide.Affects Crush at 10:00

wide straddle quote The T−1 straddle’s bid-ask spread was wide relative to its own price, so every number read off that quote inherits the width. Published on purpose — the friction is real — but kept off the board’s sort, and marked ≈ where its rank is shown.Affects Implied (naive) · Short-straddle P&L
