Session Read 2026-09-11: 13 of 20 Pairs Higher
This post covers the completed daily session of 2026-09-11 across the 20 USD-quoted crypto pairs tracked by Skia Paper from Coinbase Exchange daily candles. The session has closed; the figures below are final.
The session was classified dispersed — a label that describes the spread of outcomes observed on that single day, not a characterisation of any trend or forecast of what follows.

What the Session Did
Thirteen of the 20 pairs closed higher on 2026-09-11, with a median session change of +0.88%. The strongest pair was SOL at +3.89%; the weakest was ATOM at -8.53%. The gap between them — the dispersion figure — was 12.42 percentage points, which is the primary reason the session carries the dispersed label.
The full table shows where each pair closed inside its own 30-day high-low range (range position). SOL closed 78% of the way up its 30-day range, and ETH closed 81% up its own — both among the higher range-position readings of the session. ATOM, despite a strong 30-day gain of +17.31%, closed only 39% up its 30-day range after the session's sharpest single-day decline. The table also shows that several pairs with negative session returns — DOT (−5.16%), NEAR (−3.37%), and ICP (−3.08%) — carried strong 7-day figures of +15.57%, +8.64%, and +10.32% respectively, meaning those session declines arrived inside a recent run-up. STX's 30-day figure of +104.86% was the most extreme on the board, though its session change was essentially flat at −0.04%.
The seven pairs that closed lower were clustered in the lower half of the session-change distribution; no pair was near zero on both sides of the ledger simultaneously, which contributed to the wide dispersion reading.

The Regime This Session Describes
A dispersed session is distinguished from a broad-advance or broad-decline by the size of the spread between the strongest and weakest pair, not simply by the direction of the majority. On 2026-09-11, breadth was positive — 13 of 20 higher — but the 12.42-point gap between SOL and ATOM was wide enough that the session's character was defined more by divergence than by a common directional move. A broad-advance session with the same breadth would typically show a much narrower dispersion, with most pairs clustered closer to the median.
A compressed session sits at the opposite end: many pairs move, but within a tight band. A mixed session tends to show neither strong breadth nor wide dispersion. The dispersed label on this session reflects that individual pairs moved in meaningfully different magnitudes and directions, making the median a less representative summary of what happened than it would be in a compressed or broad-advance session.
What Dispersion Means for Execution Cost
On a dispersed session, the range of moves on show is wide — from +3.89% (SOL) to −8.53% (ATOM) — but that spread exists across different pairs, not within a single one. For any individual pair, the session change is the only move available to a participant who entered at the open and exited at the close. A round-trip on a typical spot pair on Coinbase Exchange carries a taker fee that, as of the published fee schedule, ranges from roughly 0.05% to 0.60% per side depending on 30-day volume tier, meaning a round-trip floor of approximately 0.10% to 1.20%. Against the median session move of +0.88% on 2026-09-11, a round-trip at mid-tier rates consumes a material fraction of the available move before slippage is considered.
Pairs that moved less than 1% in either direction — ADA at +0.88%, BTC at +0.88%, LINK at +0.79%, AVAX at +0.53%, STX at −0.04%, HBAR at −0.48% — sit in a range where standard taker fees alone represent a significant portion of the gross move. Wider-moving pairs such as ATOM (−8.53%) or APT (−7.18%) produced session changes large enough that fees are a smaller fraction, but slippage in a fast-moving pair can widen the effective cost further. The dispersion on this session means cost as a fraction of move varied considerably across the board.
What One Session Does Not Establish
A single daily session is a sample of one. The dispersed classification describes the shape of 2026-09-11's outcomes; it does not establish that dispersion is a persistent condition, that the pairs which led this session will continue to lead, or that the pairs which declined have reached any floor. ATOM's −8.53% session decline arrived alongside a 7-day gain of +9.74% and a 30-day gain of +17.31% — the session figure and the longer figures pull in opposite directions, and neither cancels the other out as evidence of anything forward-looking.
Range position figures show where a close sat inside a completed 30-day window. A pair closing at 81% of its range (ETH) has done so within a range that is itself a historical artifact; the range will shift as new sessions close, and today's high range-position reading carries no implication about tomorrow's. The regime label is a descriptor of a session that has ended, not a signal about what the next session will look like. Dispersed sessions have been followed by sessions of every other classification in the taxonomy.
The 2026-09-11 session is one data point in an ongoing record of daily closes across 20 pairs — useful for understanding the shape of that particular day, and not much else on its own.
