Spot and volatility regime

Spot settled around 2,685 and remains in the upper half of the monthly ATR band. On the monthly ATR frame, the upper trigger at 2,658 has been reclaimed and the lower trigger at 2,275 is still far below, so the higher-timeframe regime remains neutral-to-repair. The monthly range has already traversed about 56% of ATR, which is consistent with a repair move that is still alive rather than complete.

On the daily and 4h lenses, the latest closes are both around 2,685, well above the lower moving-average base implied by the broader trend structure, though the fact set does not provide the full EMA stack for this snapshot. Against the recent daily sequence, price has backed off from the 2,777 high, so today reads more like high-level digestion than a regime failure.

IV term structure, skew & DVOL regime

Implied vol surface

The term structure shifted higher, with the front end repricing faster. ATM IV is now about 55.2%, up sharply from roughly 37% the day before, so short-dated vol was clearly re-marked. The 25P, 30P and neighboring lines also moved up materially, which says this is a broad surface repricing rather than a single-strike anomaly. The far end remains rich too, especially in the 5C/10C/15C area, so upside tails are still carrying real premium.

On skew, puts remain richer than ATM and the front/middle end put premium firmed further. The call wing did not collapse either, which tells us the market is still pricing upside tail optionality rather than simply leaning bearish. Net: steeper skew, higher surface, and more expensive near-dated protection.

DVOL index

DVOL sits around 51.6%, marginally higher on the day and firmer versus the prior week, although still below the high-vol regimes seen over the last year. On the 1Y window, the rank is around 13 with percentile around 16; on the 3M window, it is back into a mid-to-lower zone with rank around 39 and percentile around 53. That is a repair in vol, not a panic spike.

The key read is that volatility is stabilizing and re-pricing before spot fully catches up. That is consistent with a market that is starting to pay for the next 1–2 weeks of realized volatility rather than simply chasing realized weakness.

Options chain structure

The chain remains front-end centered, but today’s turnover and Open Interest (OI) migration were most active in the 0DTE (expires same calendar day) and 1–7D buckets, which means the market is rapidly re-marking near spot. 25SEP26 remains the largest front-end anchor, 30OCT26 provides middated support, and the sizeable 25DEC26 call base remains in place, so the far-end bullish structure has not been unwound.

By strike, the most important activity clustered around 2,700, 2,800, 2,850 and 2,900, while 2,600 continues to accumulate put-side interest. That keeps the market framed as “spot-adjacent range + upper-edge pressure + lower protection.” Higher strikes like 3,000, 3,200 and even 3,500 still carry meaningful call positioning, so the upside structure is still there; it is just trading with a shorter horizon now.

Net greeks and expiry × delta structure

Net greeks weakened materially over the last 24h. Net delta, net gamma and net vega all turned negative, and the most important inflection is in the front and middle of the curve: the prior day’s long-vol/long-gamma tone was replaced by short-vol/short-gamma behavior. On an expiry basis, 24SEP26 and 25SEP26 remain the largest flow centers, but the direction is no longer one-sided; 30OCT26 and 25DEC26 also show meaningful reallocation of vega and gamma.

By strike, 2,800 stands out as the clearest negative vega / negative gamma pressure point, with 2,850 and 2,300 also leaning defensive. In contrast, 2,600, 2,750, 3,000 and 3,200 still show a mix of buying and hedging interest. So the market is not simply Option delta-risking one-way; it is rebalancing both sides around the 2,685 area, and short-dated gamma has shifted from support to constraint.

Block and combo block trade flow (24h)

Block and combo prints in the 24 hours through the report snapshot at 00:00 UTC on Sep 24 (rolling window, not the calendar report day). The key change is unambiguous: net vega flipped from positive to about -9,739.8, net gamma also turned negative, and net delta turned negative as well. In other words, larger tickets moved from buying vol / buying direction to selling vol / selling direction.

Structurally, block-only still dominates, but combos, straddles, strangles and calendar/diagonal structures were all active. The biggest weights were concentrated around 2,800, 2,750, 2,850 and 2,300, plus structures in 25SEP26, 30OCT26 and 25DEC26. In particular, the 27NOV26 and 30OCT26 areas showed clear vol-selling / gamma-selling behavior, while the 25DEC26 wing still retained some far-end buying support.

For the desk, this reads like volatility supply near the upper edge rather than chase buying. If that seller-led pattern persists, short-dated IV can stay sticky, but clean spot continuation may be harder to achieve.

2. What Changed vs Prior Session(s)

Four things mattered most today:

1. Spot shifted from strong repair into upper-edge digestion.
   Yesterday’s message was “above 2,659 and extending.” Today is a test of whether 2,685 can hold as the market works off the upper edge.

2. Volatility moved higher, but not in panic fashion.
   DVOL firmed, and the entire surface repriced higher, especially on the front end. This looks like risk re-marking rather than disorderly vol expansion.

3. The options chain shifted from long gamma / long vega into short-dated seller structure.
   The prior day was more constructive on vol; today looks more like premium collection and short-dated hedging pressure. The activity in 0DTE (expires same calendar day) and 1–7D confirms that this was concentrated nearest spot.

4. Block/combo flow flipped negative.
   The change from net vol buying to net vol selling is the cleanest structural signal of the day, and it weakens the prior day’s bullish positioning tone.

Bottom line: the repair trend is still intact, but the market is now repricing that repair as upper-edge digestion rather than a clean breakout continuation.

3. Multi-Day Context

Over the last week, ETH has moved from low-base range repair to the upper edge and then above it. On Sep 16 it was still near 2,420, on Sep 18 it reclaimed 2,600, on Sep 20 it was pressing 2,659, on Sep 21–22 it cleared the upper trigger and extended, and today it entered the digestion phase above that trigger.

So the weekly structure has evolved from “range repair in the middle” into “upper-edge breakout and follow-through.” Today’s pullback did not break the weekly gain or send price back into the lower half of the ATR band, so this is better interpreted as consolidation after a structural shift, not failure.

Relative to the past several sessions, today reinforces the weekly theme that the upper trigger has been broken and now needs turnover/consolidation. It weakens the idea of a smooth one-way grind higher. In other words, the directional bias is still constructive, but the path is now more two-sided and volatility-sensitive.

4. Key Levels and Risk Zones

Upside areas to watch

• 2,700: the nearest intraday balance point and the level most likely to attract short-term two-way trading.
• 2,750 / 2,800 / 2,850: the main upper pressure band in the chain and in greeks; 2,800 is especially important.
• 2,900 / 3,000: if 2,800 is reclaimed and held, these become the next likely hedging and chase levels.
• 3,200: still backed by meaningful medium-term call Open Interest (OI) and can be re-rated if vol expands.

Downside areas to watch

• 2,660–2,659: the monthly upper trigger zone, and today’s immediate structural line in the sand.
• 2,600: heavy put-side interest and active turnover; losing it would likely intensify short-dated protection demand.
• 2,500 / 2,450: the first meaningful pullback buffer and a zone where short-dated gamma could shift again.
• 2,300: deeper defense; still relevant because the chain and flow retain meaningful legacy positioning there.

Risk-zone interpretation

The main risk is not a major selloff; it is a failure to hold the 2,685 area and a drop back below 2,659. If that happens, short-dated IV can stay elevated and the 2,600 zone will likely re-accumulate protection demand. Conversely, if spot reclaims 2,700 and extends toward 2,750/2,800, the upper-edge digestion will convert into a second push higher.

5. Scenario Map for Next Session

Scenario 1: Hold 2,660–2,659 and retest 2,700/2,750

If spot continues to defend the monthly upper trigger and buyers can lift price back above 2,700, then today’s vol-selling flow may simply have been upper-edge supply. In that case, 2,700 / 2,750 / 2,800 remain the key chain levels, short-dated IV can stay firm, and spot should have better upside elasticity.

Scenario 2: Lose 2,659 and rotate back toward 2,600

If 2,659 is lost again, the market will quickly define today as failed upper-edge acceptance, and 2,600 protection will matter more. Short-dated gamma constraints would strengthen, 0DTE (expires same calendar day) and 1–7D hedging would likely intensify, and the front-end vol surface could remain relatively bid.

Scenario 3: Reclaim 2,800 cleanly

If 2,800 is taken back convincingly, 2,900 and 3,000 likely become the next attention zone, and the medium-term 3,200 call base could be reactivated. In that case, today’s vol supply would look more like consolidation at the upper edge than a trend top.

Next-session monitoring list

• Can spot reclaim and hold 2,700?
• Does 2,659–2,660 break again?
• Do trades and Open Interest (OI) continue shifting into 2,700 / 2,750 / 2,800?
• Does 0DTE (expires same calendar day) and 1–7D keep dominating net gamma changes?
• Does DVOL keep grinding higher, or stall around 52%?
• Does block/combo flow continue to show net vol-selling / net gamma-selling?

6. Trader Focus

• Today is not a trend break; it is a repricing after an upper-edge breakout.
• Spot remains above the monthly upper edge, but short-dated vol and hedging demand have clearly risen.
• The chain is still trading the 2,600–2,800 and 2,900–3,200 ranges.
• The flip in block/combo flow from net vol buying to net vol selling is the most important structural change to watch.
• The key levels for tomorrow are still 2,659 and 2,700: the first is the structural floor, the second is the threshold for renewed strength.

Interpretation

The market is not saying “go higher” as cleanly as yesterday; it is saying “re-distribute risk at a higher level.” ETH still retains the weekly repair trend, but the options market is now pricing more short-dated volatility and a more complex battle around the upper edge. For experienced options traders, the key question is no longer direction alone, but whether spot is simply retesting the breakout area or starting a longer period of high-level consolidation.
