This post covers the daily session that closed on 2026-09-01, sourced from Coinbase Exchange candles across 20 USD-quoted crypto pairs. The table rendered alongside this piece shows each pair's close, session change, 7-day and 30-day change, and where the close sat inside that pair's own 30-day range.

The session carried a mixed regime label — the classification applied to a session that has already closed, describing what the data showed, not what follows from it.

What the Session Did

Nine of the 20 pairs closed higher on 2026-09-01, leaving eleven in negative territory. The median session change was -0.17%, a figure close enough to flat that the aggregate barely tilted negative. The headline spread between the strongest and weakest pair was 6.77 percentage points — DOT led at +3.78% and SOL lagged at -3.00%.

The range-position column adds texture to those session moves. SOL closed at 72% of its own 30-day range despite posting the session's worst decline, meaning it had arrived at this session from a relatively elevated position within recent history. DOT, the session leader at +3.78%, sat at only 48% of its 30-day range — roughly the middle of its recent corridor. STX and BTC both closed at 80% of their respective 30-day ranges, while APT sat at just 18%, the lowest range position in the cohort. IMX (74%), LINK (70%), and ICP (65%) all closed in the upper portion of their ranges.

On the 30-day column, the cohort was broadly positive — STX carried a 30-day change of +82.94%, the outlier of the group, while SOL showed +35.90%, ETH +28.35%, and XRP +24.45%. APT (-2.98%) and OP (+9.40% on 30d but -6.05% on 7d) illustrated that shorter and longer windows did not always point the same direction. The table captures those divergences more completely than any summary can.

Regime: What Mixed Means Here

A mixed label is applied when the session produces neither the broad directional agreement of a broad-advance or broad-decline, nor the tight clustering of a compressed session, nor the extreme spread of a dispersed one. On 2026-09-01, breadth at 9/20 was close to even, the median was nearly zero, and dispersion at 6.77 percentage points was notable but not extreme enough to dominate the picture on its own.

What distinguishes this from a compressed session is that the 6.77-point spread between DOT and SOL is meaningful — compressed sessions typically show the cohort moving within a narrow band regardless of direction. What distinguishes it from dispersed is that a dispersed label would require more of the field to be pulling sharply in different directions, not just the two poles. The near-zero median alongside split breadth is the defining characteristic of the mixed classification as it applied here.

Cost Conditions on a Mixed Session

A typical maker fee on a major spot exchange runs in the range of 0.00%–0.10% per side, and a taker fee commonly sits between 0.05% and 0.10% per side, producing a round-trip cost floor in the range of 0.10%–0.20% depending on tier and order type. On a session where the median move was -0.17% and the majority of individual session changes fell inside ±2.00%, that fee floor consumes a substantial fraction of the gross move for any strategy that opened and closed within the session.

Only the pairs at the outer edges of the dispersion range — DOT at +3.78% or SOL at -3.00% — produced session moves large enough that a round-trip fee would represent a small percentage of the total swing. For the middle of the field, where pairs like AVAX (-0.17%), ATOM (-0.51%), and HBAR (+0.57%) clustered, a single round-trip at taker rates would have been the same order of magnitude as the move itself. Strategies that depend on holding period rather than intraday frequency face a different arithmetic: the 30-day changes in the table, ranging from -2.98% (APT) to +82.94% (STX), represent the window over which a longer-hold approach would need to be evaluated against its own cost structure.

What One Session Does Not Establish

A single daily session is a sample of one. The mixed label describes what the data showed on 2026-09-01; it carries no predictive content about the session that follows. Regime classifications are applied retrospectively, and the boundary between mixed and compressed, or mixed and dispersed, is a matter of degree — a different day with similar breadth but tighter clustering would receive a different label.

The range-position figures describe where each pair's close sat relative to its own 30-day high and low. A high range position does not indicate that a pair is overextended or due for a reversal; it records a historical fact about one candle's location. Similarly, a low range position such as APT's 18% does not signal that a floor has formed — it records that the close was near the lower end of a specific 30-day window that has now passed.

The 7-day and 30-day columns show what happened over those windows, not what those windows predict. Pairs with strong 30-day gains and weak session performance — SOL (+35.90% on 30d, -3.00% on the session) being the clearest example — are described by those two facts simultaneously. No inference about mean reversion or momentum continuation is warranted from a single session's data.

The 2026-09-01 session closed with the cohort nearly evenly split, a median barely below zero, and a dispersion figure wide enough to matter for execution but not wide enough to define the day on its own — the definition of a mixed tape.

Note: This explains how a mechanism works. It is educational and is not financial, investment or trading advice, not a recommendation, and not a signal service. Any figure describes a session that has already closed and says nothing about what happens next. Trading cryptoassets risks losing money, including all of it.
