On deep days the with-trend touch is the more frequent of the two: the move tends to extend, not correct.

50 % is a coin flip; the interval under each number is the 95 % range of the true frequency.

The close is what a position held to the end earns on the underlying, before costs; the two extremes are what it could have taken or lost along the way. |t| ≥ 2 is roughly 95 % confidence that the mean is not zero.

On 31 deep days the move from the 09:30 open to 15:40 was at least 0.75 %. By High / Low the price then touched 0.20 % against the trend in 65 % of them and with the trend in 74 % (shallow days: 44 % / 56 %); the close was against the trend in 39 %, the average move to 16:00 — -0.04 % (t = -0.6). There is nothing to trade here: the price wiggles both ways and closes on either side about equally.

1 · Does a deeper move make the correction more likely?

PLTR · 0DTE sessions · move from the 09:30 open to 15:40 · window 15:40–16:00

Every "touch" is by the High and Low of each minute in the window, measured from the window-start price. Each threshold has two columns: against the trend and with it — when both grow together with depth, that is volatility, not a correction. Rows are nested: "≥ 1.00 %" contains "≥ 1.50 %". Bars are proportional to the percentage.

2 · When inside the window is the correction reached?

deep days (≥ 0.75 %, n = 31) vs shallow (< 0.50 %, n = 9)

Top: the share of days that have touched 0.20 % from the window-start price by the end of each minute, by High / Low — against the trend and with it. Bottom: the average High − Low range of each minute, and the running close-to-close move of deep days.

"The extreme fell here" is the segment holding the deepest counter-trend (or the furthest with-trend) point of the whole window; the last segment collects every day whose move ran into the close. "Inside the segment" measures each five minutes on their own, from the segment's opening price.

3 · How many minutes before the close to enter?

direction and depth are read at the entry minute itself; exit at 16:00

Each row is its own experiment: a position against the trend opened at that minute on days that had moved at least 0.75 %. "To the close" is the close-to-close result; the two High / Low columns are the furthest the price went from the entry in the trader's favour (against the trend) and against them (with the trend) before the end. Six entries are compared at once, so one mildly significant row among six is expected by chance.

Δ is the counter-trend touch rate minus the with-trend one on deep days: the part of the touching that is a correction rather than noise. "Best of 6 entries" is the largest mean close-to-close move among the six five-minute entries of section 3 — a selected maximum, so its t overstates the evidence. The pooled row treats the fourteen names on one day as one day when computing t.

Methodology and data

What is measured by High / Low and what by close. The snapshot keeps, for every minute from 15:30 to 16:15, its High, Low and close. Every "touch", every "max against / with trend", the "extreme fell here" shares, the "inside the segment" excursions and the minute range use the High and Low of each minute, so any swing inside a minute is captured up to its extremes. "To the close", "closed against" and the running close-to-close line use the close of the minute ending at the window end. Minute bars do not reveal the order of ticks inside one minute: a High and a Low in the same minute cannot be ordered.

Direction and depth. The day's direction is the sign of the change from the anchor (the 09:30 minute-bar open, or the close of the minute ending at 09:35) to the close of the minute ending at the window start. Its size in percent of the anchor is the depth. A zero change has no direction and is left out.

Touches and extremes. Inside the window the counter-trend extreme is the distance from the window-start price to the lowest Low (after a rise) or the highest High (after a fall) of any minute; the with-trend extreme is the mirror image. Thresholds are exact integer comparisons on microdollar prices, in percent of the window-start price. "Closed against" means the close of the minute ending at the window end is on the counter-trend side of the window-start price; the mean move is that signed difference, positive when against the trend. Give-back is the counter-trend extreme divided by the depth, shown only for moves of at least 0.25 %.

Clocks. A boundary at minute M is the close of the one-minute aggregate ending at M: the 16:00 value is the close of the 15:59 bar, not the closing auction. The auction print (the vendor's official daily close) is compared with that 15:59 close in the day table and below. Single-stock options stop trading at 16:00; ETF options at 16:15, so an ETF window may end there.

Closing auction. PLTR: median gap between the official close and the 15:59 close 0.012 %, the auction went against the day's trend in 38 % of days (n = 42).

Sessions. Only full 09:30–16:00 sessions with every regular minute present; shortened sessions and days with a missing regular minute are listed as exclusions. A "0DTE" session of a stock is one on which the vendor lists an option contract of that name expiring that day; the ETFs have an expiry every session. Measured expiry weekdays are shown next to each name.

Statistics. Frequencies carry 95 % Wilson intervals. Means carry a standard error and t = mean / SE; for the pooled row the standard error is clustered by day, so the fourteen names of one day count as one observation. Nothing is corrected for the number of comparisons or for the hypothesis having been formed after looking at 2026. The verdict badge follows a fixed rule: "lean" when both the closed-against frequency's lower 95 % bound is above 50 % and the mean move's lower bound is above zero; "hint" when the mean is positive with t ≥ 1 or the closed-against frequency exceeds 55 %; "none" otherwise.
