Spot and volatility regime

BTC spot is around 78,287, down about 0.64% on the day but still up roughly 1.6% over the week. The daily chart remains above the full EMA20/50/100/200 stack, so the medium-term trend is intact. The 4h chart is still below EMA20, but EMA50/100/200 continue to support price underneath; that reads more like failed short-term repair and sideways digestion than structural damage.

The ATR framework remains neutral. Price has traversed only about 37% of the monthly ATR range, sitting in the middle-to-lower half of the band, still below the upper trigger near 82,428 and well above the lower trigger near 74,634. In other words, spot is still inside a regime where the trend has not broken, but short-horizon direction remains unclear.

IV term structure, skew & DVOL regime

Implied vol surface

The term structure is still upward sloping, with front-end ATM IV roughly in the 25.9% to 41.5% area and the back end gradually lifting into the low-to-mid 40s. The curve is not inverted. Short-dated and front-end vols are the ones doing the heavy lifting, which says the market is paying up for near-term price swings rather than only for longer-dated risk.

Skew remains put-rich versus ATM, and the front-end wings richened together across several near-dated tenors. The 10SEP/11SEP/12SEP area shows a clearer skew lift, which looks more like localized tail-risk repricing than a broad, uniform vol bid.

DVOL index

DVOL is around 40.2%, edging higher again versus the prior session. On the 1Y window, IV Rank / IV Percentile still sits in a relatively low band, with Rank near 13 and Percentile near 39. On the 3M window, however, DVOL is much more elevated, with Rank near 43 and Percentile near 73, showing that current vol is no longer suppressed relative to more recent history. Regime-wise, vol is repairing, but not yet in an extreme high-vol state.

Options chain structure

The options chain remains concentrated in near-dated and 8–30 day expiries, with 25SEP still the largest Open Interest (OI) node and activity in 1–7 day and 0DTE (expires same calendar day) tenors increasing. The 81k, 80k, 82k, and 84k strikes remain the main trading band. 80k remains the most important pivot because it sits at the intersection of spot sensitivity, near-term Open Interest (OI), and multiple tenors. On the upside, 85k, 86k, and even 95k calls continue to build; on the downside, 75k, 72k, and 70k puts remain substantial.

By Tenor bucket rollup, 25SEP remains the main battlefield for Open Interest (OI) and volume, while 11SEP/12SEP/13SEP carry a growing share of short-horizon turnover, which tells you short-dated hedging and event trading are becoming more active. Longer-dated buckets like 25DEC, 26MAR27, and 25JUN27 remain present, but they are more structural than intraday-dominant.

Net greeks and expiry × delta structure

24h net Greeks are layered rather than one-directional.

• 30OCT26 leaned net positive delta, net long vega, and net long gamma, so there is still some medium/long-dated positive vol accumulation.
• 25SEP26, 18SEP26, and 12SEP26 were more consistent with vega selling, gamma selling, and theta collection, so the near-to-intermediate end is still being supplied with vol.
• 10SEP26 had notable gamma buying, but the delta mix was noisy, which is consistent with 0DTE (expires same calendar day) behavior.

By strike, 82k and 84k stand out as the clearest positive vega/gamma accumulation zones. 83k, 78k, 75k, and 72k show more pronounced vol/gamma cleanup or supply. The 80k area remains a multi-Tenor bucket rollup cluster where flows are conflicting rather than cleanly directional.

Block and combo block trade flow (24h)

Block and combo prints in the 24 hours through the report snapshot at 00:00 UTC on 2026-09-10 (rolling window, not the calendar report day).

Overall large-trade flow shifted away from yesterday’s clearer net long-vol tone toward a more mixed structure; net vega edged slightly negative and net gamma compressed toward a near-neutral to mildly short reading. Block-only trade flow still dominates, but proportionally more calendars, strangles, straddles, and spreads appeared in the mix, so this is more about Tenor bucket rollup rotation and relative value than a clean directional bet.

What matters most:

• Call calendars and diagonals between 25SEP and 11SEP/12SEP remain active, which points to ongoing short/medium-dated vega exchange.
• Put spreads and put calendars around 18SEP/25SEP keep showing up, consistent with downside protection and Tenor bucket rollup restructuring.
• The 80k/79k/76k/75k region is where the most activity clusters, so hedging around the spot pivot still dominates.
• 30OCT call-side large orders are still present, but they now look more like structured buying than outright chase.

2. What Changed vs Prior Session(s)

• Price: BTC slipped from about 79.1k to around 78.3k, a modest decline that still fits the “repair, then digest” pattern.
• Structure: the daily trend remained intact, but 4h still failed to reclaim EMA20, so short-term momentum stayed soft.
• Volatility: front-end IV continued to rise and DVOL moved above 40%, making short-dated vol more expensive than yesterday.
• Options chain: 0DTE (expires same calendar day) and 1–7 day activity increased, so the short end moved further to the fore.
• Greeks: yesterday’s cleaner long vega/gamma tone shifted into a more mixed, marginally vol-selling structure, especially in near/intermediate tenors.
• Block/combo: large flows no longer show a one-way long-vol message; structured hedging and Tenor bucket rollup switching took a bigger share.

3. Multi-Day Context

Over the past week, the dominant theme has been: the medium-term trend has held, but short-term momentum has repeatedly faded, with 80k becoming the market’s central pricing anchor.

• From Sep 3 to Sep 6, spot had recovered above 80k and the daily/4h charts were stronger.
• From Sep 7 to Sep 8, spot rolled back into the 79k–78.4k area, the 4h EMA20 was lost, but the broader trend still held.
• Today’s session added a new layer: price did not break down further, but front-end vol and short-dated skew lifted first, which means the market is paying more for local swings and tail risk.

Relative to the week-long progression, today reinforces rather than weakens the emerging structure: spot is still range-bound inside the larger trend, but the vol surface and short-dated activity are becoming more sensitive to near-term moves. This is a confirmation of localized repricing, not a return to a clean directional trend.

4. Key Levels and Risk Zones

• 80k: the core pivot. Spot, near-dated Open Interest (OI), 0DTE (expires same calendar day)/1–7 day activity, and multiple Greek concentrations all cluster here.
• 81k–82k: the first layer of call supply; if the rebound stalls, this zone can act as a lid.
• 84k–86k: the second supply zone, with 25SEP and some longer-dated call inventory remaining thick.
• 78k–77k: the nearest support / pinning band around spot, with heavy near-dated Open Interest (OI) and turnover.
• 75k–72k: the main downside protection zone; whether this area absorbs supply or expands risk will matter.
• 70k: deeper tail-risk support, still carrying meaningful put inventory.

5. Scenario Map for Next Session

Scenario 1: Another push above 80k

If spot reclaims 80k and pushes toward 81k/82k, the first test will be whether short-dated call supply absorbs the move. Watch whether 0DTE (expires same calendar day) and 1–7 day calls continue to be bought, or whether the move stalls into additional call-wall buildup. If call supply thickens again at 81k/82k, the move is more likely to become a capped range test than an outright breakout.

Scenario 2: Continued chop around 78k–80k

If spot stays trapped around 78k–80k, pinning risk remains high. The key tells will be whether near-dated Open Interest (OI) and turnover continue to rotate around 80k/79k/78k, especially in 25SEP and the 11SEP/12SEP buckets.

Scenario 3: A slide toward 77k/75k support

If spot weakens again and tests 77k/75k, watch whether put-side activity and downside hedging reaccelerate. Stronger put spread / put calendar expansion in 18SEP/25SEP would suggest the market is preparing for a deeper pullback; if downside protection does not enlarge, the move would look more like passive Option delta-risking than active bearish positioning.

Monitoring points for next session

• Whether the 80k call wall and put wall continue to pin price.
• Whether 25SEP remains the dominant Open Interest (OI) carrier or whether activity shifts further into 11SEP/12SEP.
• Whether DVOL keeps rising even if spot is quiet.
• Whether 30OCT long-vol demand persists or gets overwritten by short-end vol selling.
• Whether 78k, 75k, and 72k rebuild put inventory and lift the downside protection line.

6. Trader Focus

• Today was a vol repricing day, not a clean trend-break day; front-end IV and short-dated rotation matter more than spot alone.
• 80k remains the market’s anchor, and pinning risk is highest around that level.
• Call pressure above 81k/82k and put support below 75k/72k coexist, so range tactics still make sense unless spot produces a new breakout.
• Net Greeks and block/combo flow both suggest that near/intermediate tenors are noisier than the back end; structure and Tenor bucket rollup rotation matter more than outright direction.
• The core weekly theme still holds: the medium-term trend is intact, short-term momentum is soft, and volatility is repairing ahead of price.
