Session Read 2026-09-10: 2 of 20 Pairs Higher
This post covers the completed daily session of 2026-09-10 across 20 USD-quoted crypto pairs sourced from Coinbase Exchange candles. The session closed before this piece was written; no prices in it are live.
The session carried a broad-decline classification. The table rendered alongside this piece shows the six columns Skia Paper tracks: pair, close price, session change, 7-day change, 30-day change, and range position — where each close sat inside that pair's own 30-day high-to-low range.

What the Session Did
On 2026-09-10, only 2 of the 20 tracked pairs closed higher. APT led the session at +2.36%, with its close sitting 65% up its 30-day range. ICP was the only other gainer, adding +1.11% and sitting at 68% of its range. Every other pair in the table closed in negative territory.
The median session change landed at -3.34%, with losses distributed broadly rather than concentrated in a handful of names. STX was the weakest pair at -7.62% — a notably large single-session move — and sat at 72% of its 30-day range despite the decline, reflecting how far it had risen over the prior month (its 30-day figure stands at +98.67%). Dispersion between the strongest and weakest pair reached 9.98 percentage points, a spread that indicates the session was not uniform in its severity even within a broad selloff.
Range positions across the table are informative about where pairs stood heading into the session close. NEAR closed at 81% of its 30-day range and ETH at 82%, both near the upper end of their recent corridors, even after session losses of -1.53% and -1.22% respectively. At the other end, XLM, ADA, OP, and SHIB each closed below 40% of their 30-day ranges, meaning their closes sat closer to the bottom of the range they have traded over the past month.

Regime and What Distinguishes It
A broad-decline label is applied when the majority of the tracked universe closes lower in a single session and breadth is heavily skewed to the downside. On 2026-09-10, breadth of 2/20 is near the floor of what the 20-pair universe can produce — only one configuration is more lopsided. That distinguishes this session from a mixed session, where advances and declines are roughly balanced, and from a dispersed session, where the spread between gainers and losers is wide but breadth is not strongly one-sided.
The 9.98-percentage-point dispersion figure sits above the level that would be described as compressed, where most pairs move in a narrow band regardless of direction. Here, the range of outcomes was meaningful — STX's -7.62% and APT's +2.36% are not close to each other — but the directional skew was so pronounced that the session still earns the broad-decline label rather than dispersed. A dispersed session typically requires more balanced breadth alongside the wide spread.
Several pairs carried substantial 30-day gains into this session — NEAR at +51.25%, ETH at +29.60%, SOL at +29.39% — which means the session decline occurred against a backdrop of recent strength for much of the universe, not a continuation of a prolonged drawdown in every name.
What These Conditions Mean for Execution Cost
On a session where the median move was -3.34% and the weakest pair fell -7.62%, the absolute size of price moves was large relative to typical maker/taker fee structures. Coinbase Exchange publishes a tiered fee schedule; at standard retail taker rates, a round-trip cost of roughly 0.50%–0.60% (based on the published schedule for lower volume tiers) represents a smaller fraction of a -3.34% median move than it would on a compressed session where moves of 0.20%–0.50% are common. In that narrow sense, the gross moves on 2026-09-10 were large enough that fees were not the dominant variable in whether a position's outcome was positive or negative.
Slippage is a separate matter. Broad-decline sessions can see bid-ask spreads widen on the more thinly traded pairs in the universe, particularly during the sharpest legs of a move. STX's -7.62% session loss is the kind of magnitude where realized execution prices on market orders may have differed meaningfully from the candle's close price, depending on order size and the time within the session when the trade occurred. The table reports candle closes, not transaction prices, and the gap between those two figures is not observable from daily OHLC data alone.
For strategies that clear their round-trip cost through holding period rather than frequency or size, a session of this magnitude provides a larger gross move to absorb fees against — but a single session is not a holding period, and that observation applies only to positions that were already open and closed within this one candle.
What One Session Does Not Establish
A single daily session is a sample of one. The broad-decline label describes what the session of 2026-09-10 did; it carries no predictive content about the session that follows. Regime classifications on this site are retrospective descriptions, not forward-looking signals, and the distinction matters: a broad-decline session has been followed historically by sessions of every other regime type.
The dispersion figure of 9.98 percentage points describes the spread between APT and STX on this one day. It does not describe a persistent relationship between those two pairs, nor does it indicate that the gap will persist, narrow, or widen. Pairs that appeared at opposite ends of the session return distribution have done so for reasons that are not captured in a daily candle.
Range position is similarly bounded in what it can establish. A close at 82% of the 30-day range, as ETH recorded, describes where the close sat relative to the prior 30 days of trading. It does not indicate that the range will hold, expand, or that the close is near any structurally significant level — the 30-day range is a rolling window that changes every day as old candles drop off.
STX's 30-day gain of +98.67% entering this session, followed by a single-session loss of -7.62%, illustrates how a large prior move and a sharp reversal session can coexist in the same data row without that combination implying anything about the next session. The data describes what closed; it does not narrate what comes next.
The 2026-09-10 session closed with 18 of 20 pairs lower, a median decline of -3.34%, and a dispersion of 9.98 percentage points — a day that was broad in its direction and uneven in its severity.
