Spot and volatility regime

• Spot sold off through the day and closed at 2,474; the 1D and 4H closes matched, so there was no late-session trend continuation.
• The final 4H and 1D bars carried almost no volume, which weakens the importance of the exact close as a clean directional signal.
• On the monthly ATR framework, spot remains above the 2,275 lower trigger and below the 2,659 upper trigger, with the current range covering roughly 38% of ATR. That keeps the market in mid-range digestion rather than trend confirmation.
• The provided bar history does not give live EMA comparison values for the latest bar, so the safest interpretation is that the higher-timeframe structure remains unbroken.

IV term structure, skew & DVOL regime

Implied vol surface

• The term structure remains positively sloped, but the front end lifted more aggressively today. ATM IV is roughly 37.8% on the front end, while the back/longer tenors remain around the mid-50s, so the move was a front-end re-pricing rather than a full parallel shift.
• Put wings are still bid. The 5P area sits roughly in the 57%–67% zone, and downside wings across 10P/15P/20P/25P/30P remain richer than ATM.
• The steepest change is in the near end of the curve, with more moderate lifting further out. That points to event and tail-risk re-pricing first, not a broad long-end vol breakout.

DVOL index

• DVOL rose to 54.28, up about 2.4% day over day and extending the recovery from the prior session.
• On a 1Y basis, DVOL is still in a relatively low historical band, with Rank around 18 and Percentile around 26. On a 3M basis, it has moved back into a mid-to-upper band, with Rank around 55 and Percentile around 74.
• In other words, volatility is not extreme, but it is clearly rebuilding from a subdued zone, and the 3M repair is ahead of the 1Y historical framing.

Options chain structure

• The chain is still anchored around 2,500, which remains the strongest two-sided gravity point and the main call/put wall.
• Near-dated 0DTE (expires same calendar day) and 1–7D flows continue to carry the highest turnover, while the 8–30D bucket remains the main inventory battleground. 18SEP, 17SEP, 16SEP and 25SEP are the most active rollups, so this is still a weekly/near-weekly restructuring story, not a clean handoff to far-dated paper.
• Higher strikes remain thick: 2,600, 2,700, 2,750, 2,800, 3,000 and 3,500 calls all keep meaningful Open Interest (OI). The 2,600/2,700 area is the most active upper ladder, while 3,000/3,500 serves as higher-end supply.
• Lower strikes at 2,400, 2,300, 2,200, 2,100 and 1,700 carry stable put inventory, but the strikes closest to spot are still the ones most relevant for pinning and short-horizon gamma.

Net greeks and expiry × delta structure

• 24h net Greeks flipped to net positive delta, net positive vega and net positive gamma, with net theta paid. That is a clear move away from premium selling.
• By expiry, 18SEP was the strongest buying center, followed by 25SEP, 17SEP and 16SEP. The common pattern was vega buying, gamma buying and theta paid.
• 14SEP 0DTE (expires same calendar day) still showed some vega/gamma selling, so the very front end is not fully aligned. There is still a mix of hedging/cleanup flow and active vol buying.
• On strikes, 2,600 is the strongest concentrated node for net delta, vega and gamma. 2,800, 2,750, 2,550 and 2,700 are also biased positive, while 3,000 stands out as one of the few higher strikes with net sell-vol / net sell-gamma characteristics.

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 14 (rolling window, not the calendar report day).

• In this window, block/combo flow turned net long vega, net long gamma and net long delta, reversing the prior window’s more premium-harvesting posture.
• The mix is still block-heavy, but it also includes put calendars, put ladders, call ladders, put spreads and call spreads, which tells us desks are re-building exposure structurally rather than simply buying outright.
• The main activity clustered around 2,600, 2,700, 2,800, 2,500, 2,750 and 3,000, with stronger call-side buying above spot.
• The lower side shows put structure at 2,500, 2,400, 2,200 and 1,700, but these appear more as protection, calendar positioning and ratio structures than as outright bearish aggression.
• Cross-checked with the chain and net Greeks, this block/combo window supports the view that short/intermediate vol is being re-bid.

2. What Changed vs Prior Session(s)

• Spot fell from 2,526 to 2,474, so yesterday’s recovery did not extend into a trend continuation.
• Even so, the move lower did not damage the higher-timeframe monthly ATR structure; spot remains inside the band and well above the 2,275 lower trigger.
• More importantly, the flow regime changed: yesterday’s vega selling / gamma release turned into net vega buying and net gamma buying today.
• The vol surface also shifted from a relatively calmer state into a front-end lift with richer put wings, while DVOL kept rising.
• The chain also showed heavier incremental participation in 18SEP, 17SEP and 25SEP, pointing to stronger near-week activity than the previous session.

3. Multi-Day Context

• Over the past week, ETH has remained in a monthly ATR digestion regime, with spot repeatedly rotating around the 2,500 area and no confirmed trend break.
• Sept. 10 and Sept. 11 featured more obvious downside and recovery, while Sept. 12 moved back above 2,500. Today slipped back below 2,500, but within the same broader range-repricing framework.
• The chain has repeatedly layered more inventory into 2,500–2,700 and then above 2,800/3,000/3,500, showing a stair-step migration of positioning higher.
• Today strengthens the midweek theme of structural higher strikes plus vol repair, but it also shows that front-end risk was not worked off; it was re-priced higher.
• So the week is not about a one-way breakout. It is about range re-pricing, rebuilding convexity, and re-layering structure.

4. Key Levels and Risk Zones

• Near spot:
  • 2,470–2,500: current magnet zone and the most sensitive area into the next session.
  • 2,500: the main two-sided wall and the most important balance point.
• Upside:
  • 2,550–2,600: first upper ladder, where near-week call stacking and net gamma accumulation are most visible.
  • 2,700–2,800: second upside layer with meaningful Open Interest (OI) and turnover.
  • 3,000: higher-end call inventory, more tail supply than near-term pin.
  • 3,500: further-out upper inventory, still intact.
• Downside:
  • 2,400: important short-term support/hedge zone, with active 0DTE (expires same calendar day) and 1–7D puts.
  • 2,300–2,200: secondary downside protection band, still well populated.
  • 2,275: the monthly lower trigger and the key structural risk divider.
• Volatility:
  • If spot stays below 2,500 and cannot reclaim 2,500/2,520 quickly, the rich front-end put wings and short-dated IV can still lift further.
  • If spot reclaims 2,500 and stabilizes above 2,550, front-end vol may ease, but supply and hedging around 2,600–2,700 should still slow a clean upside extension.

5. Scenario Map for Next Session

Scenario 1: Spot reclaims 2,500

• A recovery back above 2,500 and a hold over 2,520/2,550 would likely keep short-horizon gamma more controlled.
• Watch whether 2,600 call accumulation continues to roll higher and whether 25SEP keeps absorbing Open Interest (OI).

Scenario 2: Spot stays below 2,470

• If 2,470–2,460 gives way, 0DTE (expires same calendar day) and 1–7D put demand can intensify further, and front-end IV still has room to expand.
• The key strikes to watch are 2,400, 2,440 and 2,480 for pinning versus acceleration signals.

Scenario 3: Retest of 2,600–2,700

• If spot pushes back into 2,600, the upper call stack becomes active again and the 2,600/2,700 gamma concentration will matter for whether the move stalls.
• A clean move through 2,700 would shift attention to the 2,800/3,000 inventory layers.

Monitoring points

• Does the 2,500 two-sided wall hold, or does flow migrate higher?
• Do 18SEP and 25SEP continue to show net gamma and vega buying?
• Does 0DTE (expires same calendar day) remain a source of gamma selling, or does it align with the broader vol-buying tone?
• Does DVOL continue to climb out of the low historical band toward the stronger 3M zone?
• Does block/combo flow stay call-biased and structure-heavy, or does it revert to premium selling?

6. Trader Focus

• Today was not a trend-confirmation day; it was a range-repricing day with a vol bid.
• 2,500 remains the critical magnet, with 2,600/2,700 forming the next important structural layer.
• Front-end IV and downside wings still have room to reprice higher if spot cannot quickly reclaim 2,500.
• Net Greeks and block/combo flow both shifted from selling vol to buying vol, which matters more for near-dated structures than for far-dated paper.
• The week’s slow structural move higher remains intact, but today makes clear that it is unfolding with more expensive short-end protection and more active gamma payment.
