This is the session read for the daily candle that closed on 2026-07-31, sourced from Coinbase Exchange spot data across 20 USD-quoted crypto pairs. The session has fully closed; today's candle is still forming and is not described here.

The table rendered alongside this piece carries six columns: pair, close price in USD, session change (open-to-close), 7-day change, 30-day change, and range position — where the close sat inside each pair's own 30-day high-to-low range, with 0% at the floor and 100% at the ceiling.

What the Session Did

On 2026-07-31, 17 of the 20 tracked pairs closed lower on the session, placing this candle in the broad-decline regime. Breadth was 3 of 20 — meaning only HBAR (+0.56%), ICP (+0.24%), and XLM (+0.18%) finished above their respective opens. The median session change across all 20 pairs was -1.92%.

Dispersion — the gap between the strongest and weakest session returns — measured 4.69 percentage points, with HBAR at +0.56% on one end and ATOM at -4.14% on the other. That spread is moderate: wide enough that pairs did not move in lockstep, but not so extreme as to suggest isolated idiosyncratic events dominated the session.

Range-position readings, visible in the table, tell a consistent story. The majority of pairs closed near the lower end of their own 30-day ranges. ATOM, OP, IMX, SOL, and APT all sat at or below 6% of their 30-day ranges, indicating their July 31st closes were among the lowest prices those pairs had printed in the preceding month. ETH was the notable outlier, closing at 69% of its 30-day range despite a session loss of -2.93% on the day, reflecting that its 30-day period (-1.92% median) had been relatively constructive. LINK closed at 54% of its range for similar reasons. BTC, down -2.93% on the session, sat at 45% of its 30-day range. These elevated range positions among the larger-cap pairs contrast sharply with the sub-20% readings that dominate the rest of the table.

On the 7-day horizon, the picture was also broadly negative: 14 of the 20 pairs showed negative 7-day changes, with SHIB (+12.68% over 7 days) and ADA (+2.63%) among the few exceptions. On the 30-day horizon, the split was roughly even — some pairs such as ETH (+15.74% over 30 days) and LINK (+11.07%) retained meaningful gains, while FET (-20.96%), STX (-16.66%), and XLM (-12.73%) showed sustained weakness across the full month.

Regime Description: Broad Decline

The broad-decline label is applied when the majority of tracked pairs close lower and breadth is clearly skewed to the downside — as it was on 2026-07-31 with 3 of 20 pairs advancing. This distinguishes the session from a mixed regime, where advances and declines are more evenly distributed, and from a compressed regime, where moves across all pairs are small regardless of direction.

A broad-decline session with 4.69 percentage points of dispersion sits in an intermediate zone. The decline was not perfectly uniform — the three pairs that closed higher did so by small margins, and the losses ranged from -0.21% (SHIB) to -4.14% (ATOM). This is not the tight, near-zero-dispersion compression that sometimes precedes sharp directional moves, nor is it a highly dispersed session where a handful of pairs diverge dramatically from the group. It is a session where selling pressure was widespread but uneven in magnitude.

What the regime label describes is the character of the session that closed on July 31st. It is a classification of what happened, not a characterisation of what the market is doing in any ongoing sense.

Cost Conditions on a Broad-Decline Session

On Coinbase Exchange, maker fees for most retail tiers sit in the range of 0.40% to 0.60% per side as of mid-2026, implying a round-trip cost floor of roughly 0.80% to 1.20% before spread and slippage are added. The median session move on 2026-07-31 was -1.92%. That means the median pair's session move was larger than a round-trip fee floor, but not by a wide margin — a move of -1.92% leaves limited room once execution costs are accounted for on a same-session basis.

For pairs at the lower end of the dispersion range — SHIB at -0.21%, AVAX at -0.78%, NEAR at -0.83% — the session move was smaller than or comparable to a round-trip fee at standard retail tiers. On those pairs, a position opened and closed within the session would have been working against a cost structure that exceeded or closely matched the gross move available. The larger moves — ATOM at -4.14%, OP at -3.41%, LINK at -3.32% — provided more gross room, though slippage on less liquid pairs can compress that further.

Range positions clustered near the bottom of 30-day ranges for most pairs. When prices are near multi-week lows, bid-ask spreads on spot markets tend to widen modestly as liquidity providers reprice risk, though this effect varies by pair and is not uniform. The pairs with the lowest range positions on this session — ATOM at 3%, OP and IMX at 4% — were among the weakest movers, which is consistent with that dynamic without being caused solely by it.

Strategies that clear round-trip costs by holding period rather than frequency or size — carrying a position across multiple sessions — face a different cost arithmetic than those operating within a single candle. The session data here covers one closed candle and does not speak to multi-day holding costs such as funding on leveraged products.

What One Session Does Not Establish

A single daily candle is a sample of one. The broad-decline label on 2026-07-31 describes the character of that candle; it does not establish a trend, confirm a pattern, or indicate anything about the session that follows. Broad-decline days occur within longer uptrends, within longer downtrends, and in the middle of sideways ranges — the label alone does not distinguish between these contexts.

The regime classification is applied after the session closes. It is a description, not a signal. A sequence of broad-decline sessions would be a larger sample, but even then the classification describes what happened and carries no predictive content about direction or magnitude of subsequent moves.

Range positions near the bottom of 30-day ranges for many pairs indicate where prices closed relative to recent history; they do not indicate whether those levels will hold, be revisited, or be exceeded. A pair closing at 3% of its 30-day range has been lower than this close for very little of the past month — that is a factual statement about the closed session, not a characterisation of value or support.

Dispersion of 4.69 percentage points describes how spread out the returns were on this one session. It does not indicate whether dispersion will be higher or lower in subsequent sessions, and it does not identify which pairs within the distribution moved for structural reasons versus noise.

The 2026-07-31 session closed with 17 of 20 pairs in the red, a median decline of -1.92%, and most pairs sitting near the lower boundary of their own 30-day ranges — a single data point in a series that continues with the next candle.

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.
