What the Session Did
On 2026-09-09, 18 of the 20 tracked pairs closed lower and 2 closed higher. The median session change across all 20 pairs was -3.16%. Selling pressure was therefore not concentrated in a handful of names — it was the dominant outcome at the median, which means the central tendency of the field moved down, not just the tail.
Dispersion was notable at 16.89 percentage points, the gap between NEAR at +6.95% and DOT at -9.94%. That spread is wide relative to the median, meaning the session was not a uniform slide: a small number of pairs diverged sharply from the field while most clustered in a band of moderate-to-steep losses. The table shows the full distribution; the summary here is that the spread between outliers was large even as the middle of the field moved together.
Range positions add texture. Despite the session's losses, most pairs did not close near the floor of their 30-day ranges. BTC closed at 80% of its 30-day range, ETH at 86%, NEAR at 85%, and STX at 83%. Even DOT, the session's weakest performer at -9.94%, closed at 71% of its 30-day range. This means the session's declines generally landed on top of a 30-day uptrend rather than extending an already depressed position — the closes were lower than the open, but not low in absolute 30-day terms for most pairs.
The two advancers, NEAR (+6.95%) and STX (+0.88%), stood apart from the field. NEAR's 7-day gain of +31.73% and 30-day gain of +55.32% indicate that its session move occurred within a sustained run-up; STX's 30-day gain of +110.70% reflects an even larger prior move. Neither advancer was a quiet name.

Regime Conditions This Session Reflected
A broad-decline label is applied when the majority of pairs close lower and the median session change is meaningfully negative. On 2026-09-09 both conditions were met: 90% of pairs declined and the median was -3.16%. This distinguishes the session from a mixed regime, where advancers and decliners are roughly balanced, and from a compressed regime, where the field moves together but by a small amount in either direction.
The session also carried elevated dispersion at 16.89 percentage points. A pure broad-decline with low dispersion would see most pairs moving in a tight band downward. Here, the outlier on the upside (NEAR, +6.95%) and the outlier on the downside (DOT, -9.94%) pulled the spread wide, which means the session had characteristics of both broad-decline and dispersed regimes simultaneously. The broad-decline label reflects the dominant direction; the dispersion figure captures the structural spread that the label alone does not convey.
The elevated 7-day and 30-day figures for most pairs — ATOM at +27.31% over 7 days, DOT at +29.38% over 7 days, NEAR at +31.73% over 7 days — indicate that the session's losses occurred against a backdrop of recent gains across much of the field. The session described a single day's reversal within that context, nothing more and nothing less.
What These Conditions Mean for Execution Cost
On a session where the median move was -3.16%, a standard maker fee of roughly 0.40% to 0.60% per side (0.80% to 1.20% round-trip, as published in Coinbase Advanced Trade's fee schedule for lower volume tiers) represents a meaningful but not dominant fraction of a median-sized move. A round-trip on a pair that moved -3.16% on the session costs the participant approximately 25–38% of that gross move in fees alone at those rates, before spread or slippage.
For pairs near the median, the fee burden is material. For the outliers — NEAR at +6.95% or DOT at -9.94% — the same round-trip fee is a smaller fraction of the gross move, roughly 11–17% of the range at the extremes. Dispersion of 16.89 percentage points means the field was not uniform: the cost of being wrong about direction on a day like this, where most pairs fell, was compounded by the fact that the losses themselves were spread across a wide range of magnitudes.
Slippage risk on a broad-decline session tends to be asymmetric. When most participants are moving in the same direction, bid-ask spreads on the sell side can widen, particularly for lower-liquidity pairs. The table does not carry volume data, so the precise spread environment on 2026-09-09 cannot be read from it directly — but the regime label and dispersion figure are consistent with conditions where execution quality on smaller pairs warrants attention.
What One Session Does Not Establish
A single session is a sample of one. The broad-decline label describes what happened on 2026-09-09; it does not characterise what preceded it or what follows it. Regime labels are descriptive classifications applied after the close — they are not predictive signals, and the same label applied on consecutive days does not imply a trend any more than two coin flips of the same outcome imply a biased coin.
The structural failure of reading a single session is that it conflates noise with signal. A -3.16% median on one day sits within the normal range of daily crypto volatility. The dispersion of 16.89 percentage points is notable, but a wide spread between outliers on one day carries no established implication for the next session's spread. NEAR's +6.95% on a broadly negative day is an observation about that day; it does not establish that NEAR is structurally different from the field in a durable way.
The range position data — showing most pairs still sitting well above the floor of their 30-day ranges despite the session's losses — is a description of where prices closed relative to a trailing window. That window will roll forward. A pair at 80% of its 30-day range today will have a different 30-day range in a week. The figure describes a snapshot, not a stable condition.
Nothing in this post, including the regime label, the breadth count, the dispersion figure, or the individual pair data, constitutes a basis for inferring what any session after 2026-09-09 will look like.
The 2026-09-09 session closed as a broad-decline with high dispersion — 18 of 20 pairs lower, a median of -3.16%, and a 16.89-percentage-point spread between the field's two outliers, all within a 30-day window that had been broadly positive for most of the tracked pairs.
