hXXI Epoch conclusion + new epoch ✅ 📊 +1.8% net in BTC over 25 days Vault Ratio back at its pre-August high. One 85,000 call written on @flowdesk_co expired out of the money at 82,111. Premium kept. Implied stayed bid into the macro calendar while realized decayed: whoever was blown out of gamma in August was not there to be blown out again. We close two weeks early: implied and realized both collapsed this week and the opportunity set moved. Into the midterms the trade is TradFi vs crypto relative value, where HYPE++, Texas Hedge and Hot7 live, not the Bitcoin surface. BlackRock's PBIT (long IBIT, long put spread, short call) is hXXI's trade in an ETF wrapper. If retirement money piles in, the surface gets a permanent call seller and the premium moves into the spread between BTC and SPX skew. Our HYPE++ already trades that swap and borrows BTC to run it. Next epoch hXXI is the lender ------ 📅 New hXXI epoch --> Deposits: open now --> Trading Starts: Oct 27 --> Epoch ends: January 15, 2027 --> Fees: zero --> Cap: 25 BTC Terms: 3% fixed in BTC + up to 3% kicker if HYPE++ closes above 15% annualized The fixed leg does not depend on how HYPE++ does. The kicker does. One surface trade is binary. HYPE++ runs an ensemble. TradFi is more "fun" than crypto right now. Fade D2 at your own risk.

We decoded the @initia exploit. One signed tx at 14:59:26 UTC minted 2,000,000 AUSD out of nothing. 153 seconds later a valid @LayerZero_Core message released 1.4M real AUSD from the Ethereum adapter. $2.65M was back on Ethereum within 7m21s of the mint. Three exits, all into 0xDD92…edFA: AUSD: 1.4M from the AUSD OFT adapter, 71% of its balance, 576K left. ETH: 105 from the native-ETH OFT adapter, 96% of its balance, 4.84 left. USDC: 1.08M as fresh mints from 0x0, via Circle's CCTP. The mint was the attacker's own key calling one Move function, 135,888 gas, no bridge message involved. The token is an argument (recipient, token, amount), consistent with one wallet printing AUSD, USDC and ETH. LayerZero's DVNs then attested to burns that really happened, and an OFT adapter cannot check whether burned tokens were ever backed: each Ethereum lockbox pays at par for any Initia-side mint bug. Prep started 6.5 hours before the mint: 0.1 ETH from Tornado at 08:27 UTC, dust sends through @axelar AxelarHandler from 13:14, and a 0.006 ETH deposit at 14:37 into the same ETH adapter it emptied 29 minutes later. Every stable was ETH within 3 minutes of landing via 1inch and 0x, AUSD in 84 seconds. All 1,135.52 ETH (~$2.73M) now sits in a fresh wallet, 0x358e…CAC8. Same shape as Liquid on 6 Sep, where an Elements bug created 4,000 L-BTC and a valid peg-out paid 3,996 real BTC. Initia's DEX holds $3.50M of TVL and did $334K of volume in 24h. Its bridges carried 8x that for one wallet in 7m21s: on Initia, the deepest pool was the bridge.

AI capex funding trade imploding? From the D2 desk. @Second_Lane is offering OpenAI equity in 20M+ blocks. That is how a trillion++ private valuation discovers a clearing price. @JensenHuang on Thursday: neocloud demand is "off the charts" and "they just need working capital." Every borrower says that right before the lender becomes the equity. CoreWeave CDS has traded above 1,140bp. ELI5 👇 One company sells the shovels. Its customers borrowed to buy them and some now pay ~15.7% on the money. So the shovel company co-signed up to $100 billion of residual-value guarantees, bought ~$99bn of their equity, and committed to ~$279bn of supply. Customers got marked down. The shovel company's options still price a normal quarter. 🤔 1. PRICED. Neocloud credit CoreWeave 2031s around 80 cents, ~15.7% yield. Market-implied default odds inside a year sit in the high single digits. ~$51.6bn of debt and leases, heavy maturities 2030–2032, cash flow still far short of the stack. 2. PRICED. Oracle 2036s ~320+ bp over Treasuries. S&P cut to BBB- in July (one notch from junk) against a massive backlog. Free cash flow deeply negative last quarter. 3. PRICED. Supply Amazon, Alphabet, Meta and Oracle have issued tens of billions of IG bonds this year, a double-digit share of the overall IG market. The IG complex is functioning as a GPU layaway plan. 4. PRICED. SPV and private credit Meta's Hyperion bond (off-balance-sheet) has traded down to the low 90s from above 110. Blue Owl has capped redemptions after large withdrawal requests. In DeFi that is a withdrawal queue; in private credit it is called a liquidity feature cc @matt_levine. 5. PRICED. Big-tech equity Alphabet well off its highs after a negative free-cash-flow quarter. Meta sold off on elevated capex and negative cash flow. SoftBank (material OpenAI holder) CDS above 400bp. 6. NOT PRICED. NVDA's hidden book 👀 The 10-Q shows a $100B residual-value guarantee cap on the SB Energy / OpenAI Ohio campus, capacity-purchase commitments on unsold neocloud inventory, ~$99bn of equity in customers, and ~$279bn of supply commitments (mostly memory). Options price roughly a 5% move at ~42 vol. One of those two numbers has not read the other. 7. NOT PRICED. Microsoft Microsoft is ~22% of NVDA revenue; NVDA is a dominant share of Microsoft's capex. Any hedges, @satyanadella? 8. NOT PRICED. 2027 spend Street still models Alphabet and Amazon spending materially more in 2027 than this year. Earnings next week will test it. 9. NOT PRICED. Off-balance-sheet treatment. The market is treating Hyperion as Meta risk. Ratings agencies still carry the parent at A+. We will see how long that lasts. 10. NOT PRICED. Policy path post-election. Any "silver bullet" stimulus or industrial policy that keeps the capex train running is not in the likely @realDonaldTrump options in case of a Dem sweep. TL;DR Borrowers have repriced: CoreWeave ~15.7%, Hyperion in the 90s, Alphabet meaningfully off the highs. The lender has not: $NVDA 👀 Key dates: 28 and 29 October guides, 4 November buyback window ends, 19 November NVDA earnings. Texas is watching you, Jensen.

According to @ssmccul and @ThinkingUSD, the best edge in this market this week is long deleted posts. 😂 Same thread, 40 minutes apart. The deleted question answers itself: either $CHIP is worthless and the yield it paid for a year was decoration, or it is money-good and selling us a 9-delta put at 48% of spot is free income. There is no third reading. Put bid on @USDai_Official “unrelated to the loan book token” 🤣 still open, strike 0.02102, expiry 25 Jun 2027, numbers on the card. @derivexyz vault for settlement. 💚

Happy to be wrong on @USDai_Official, Samuel, and happier to get paid for it. Here's the trade. We buy a put on $CHIP: $1M USD notional (22.7M tokens at today's 0.044). Expiry 25 Jun 2027, ten weeks after the April cliff. 👀 We pay $50,000. At 100 vol that buys a strike of 0.02102, 48% of spot. If CHIP finishes above the strike next June, you keep the $50,000 and the thread. If it goes to zero, we collect $478,000 ($428,000 net of premium, 8.6x). An ATM put at 100 vol costs 30 cents per dollar, which is the point: nobody can hedge this book. The perp is not a hedge either; $8.9M of open interest is a market maker's playground, and $BERA ran more than 100% into its unlock. Convex or nothing. Settlement: use @derivexyz once vaults go live, or an escrow of your choosing before then. We commit to a second vault that buys more CHIP downside in size after the 16 Apr unlock. Intro available for the GOATed @derivexyz team. Same desk that called @Main_St_Finance ( BTW any news there?), @Neutrl, @papertrade_xyz,.. We are traders; being right pays less than being paid. Like Druckenmiller, we care about data and PnL. Precedent on the card. Please do not chicken out the way @ThinkingUSD did with @koolkrypto223.

The HOT Market Hypothesis 👇 xitter.cf/d2_finance/status/2108…

Forget PMH, let's talk about HMH. HOT Market Hypothesis: TradFi is turning into crypto. Money chases the best recent trade as fast as plumbing allows, and the plumbing keeps getting faster. US long-short momentum's best and worst month since 2007 landed back to back: +5.89% in June, -8.14% in July. The HOT Market Hypothesis, position paper in first reply 👇

@USDai_Official is running the @berachain playbook on a GPU loan book. Berachain spent a year on Proof of Liquidity flywheels, pre-deposit vaults and points. $BERA listed at $14.97 and trades at $0.19, down 99%. USDai promised farmers a Season 2 airdrop and announced 2.25% of supply on 14 Oct. Early claimants post allocations near 1.3%; the team has not reconciled the numbers. $CHIP is down 55% since April, with 2.76B tokens (1.4x the float) unlocking on one day in April 2027. The difference is that Berachain was a Ponzi with a bear on top. USDai is sold as a dollar, and 54% of it is loans against GPUs that nobody can hedge. THE HEDGE THAT DOES NOT EXIST @drwconvexity of DRW, 22 Oct: some of the largest data center lenders have hit their risk limits, and the lack of a hedging instrument caused credit spreads to blow out. The instrument is CME’s H100 and B200 rental futures, cash-settled on the Silicon Data indexes, due 5 Oct, with CFTC review extended to 9 Nov. The indexes are live on @TheTerminal: SDH100RT at $2.86 an hour, SDB200RT at $6.14. The futures are not. WHAT THE BANK MARKET CHARGES FOR GPUs Bloomberg loan database, 22 Oct. CoreWeave first-lien delayed-draw term loans price at SOFR plus 225 to 600 depending on vintage, 6 to 10% all-in, with OIDs of 97 to 98.5 on the wide tranches. CoreWeave’s original GPU-only SPV loans, the CCACIL vehicles, now carry a 960 bp current margin. CoreWeave unsecured: 9.25s of 2030 at 86, 9.625s of 2032 at 80.5, 12 to 14% to maturity. Applied Digital’s 9.25% secured 2030s are the clean fixed-rate comp at 102.7. The Bloomberg HY index is 327 bp over, from 264 bp on 1 May. @KobeissiLetter: $419B of AI bonds this year is the supply of all this paper, up 90% on 2025; Bloomberg shows $301B of it from public issuance, the rest private. WHAT USDAI CHARGES AND HOLDS USDai lends into the same market at 11.5% to neoclouds smaller than CoreWeave, above the secured bank rate and below CoreWeave unsecured:the mezzanine slot with a stablecoin as the liability. @DefiLlama and @arkham, 21 Oct: $263M of reserves, $261M of it PYUSD, and $311M of GPU loan principal, so loans are 54% of the dollar, up from 0.2% in January as $400M of reserves left. Largest loan is $128.9M to a listed Canadian operator with investment-grade offtake, signed 14 Oct. USDai’s own mitigants are real and worth stating: curators post first-loss capital, loans are secured on the hardware with escrowed draws, and the larger borrowers carry multi-year contracts from rated counterparties. None of that is a price hedge. Collateral is hardware that loses 45 to 65% of its value in three years, and the market that would price next year’s rental rate does not exist yet. WHO HOLDS THE YIELD DefiLlama sUSDai pool, 21 Oct: 10.17% verified APY on a 30-day window built on one day’s fee spike, 1 Oct, when 52% of the month’s fees landed and 19 of 30 days were zero. Growth of $1 since 4 March annualises at 6.75%. Exit is a 30-day queue, no instant lane. Of 4,079 holders, a wallet created 54 days ago and funded by two $50M transfers from one address holds 32%, Fluid’s vault 29%, Pendle 13%. Three addresses hold 74% of the pool. THE TOKEN Season 2 claims opened 20 Oct, run to 31 Jan, no vesting. Reserves fell 24.5% in the seven days after the announcement. On 16 Apr 2027 the investor, contributor and reserve cliffs unlock 2.76B CHIP, $134M at $0.049 against a $97M market cap, then about 44M a week to 2029. Two predictions, dated so you can hold us to them. By 16 Apr 2027 USDai ships a ‘CHIP flywheel’ with a new name before it ships a hedge (bonus if they hire @SmokeyTheBera as advisor). And the first compute futures print on CME tells every GPU lender what its book was worth all along; the only question is which side of 11.5% it lands on. Berachain’s farmers found out at $0.19. Hyperliquid.

Following Jeff's example we put the jacket on (t-shirt underneath) and sat in @Nasdaq panel on 23/5 equity trading with @GoldmanSachs , DTCC, @moomoo and Superhero. The gap to Hyperliquid's 24/7 is one hour a night and the weekend. Fungibility between the listed share and the on-chain line is far off. Two prices for one asset with no delivery between them is how the kimchi premium survived a decade, and every hour one venue trades while the other sleeps adds basis. New arb set for D2 users, alpha soon. 👀 The house of all finance already has its first multi-strategy hedge fund. D2 has run it on-chain since December 2023 and on @HyperliquidX every day since before the token existed: 33 epochs settled, 32 positive, no losing month, $648M through one account, almost $3M paid to users, no VC. Long the house on first principles, a neutral ledger with a real order book. Short every extraction experiment where an LP pool is the zero-slippage counterparty in size. The not brainless timeline / @0xLoris set p(death) = 1 on this week's one. We put that in writing in May, link in the reply. Jeff can keep the suit. The panel called 23/5 the future. We have called it Saturday since December 2023. Hyperliquid

The credibly neutral ledger Joe describes has a name. Hyperliquid clears BTC, the Nasdaq 100, SK Hynix (Seoul share and ADS), oil and SpaceX pre-IPO on one margin account, 24/7, and $648M of it went through one of our accounts. The SK Hynix bet he calls hypothetical was about a third of all @tradexyz HIP-3 volume in July, the largest stock perp on the venue. Listing is permissionless: stake 500K HYPE, deploy, fees flow to the $HYPE cleaner than a dividend. We have traded there every day since before the token existed, first HYPE fill at $2. Our call: non-crypto markets exceed half of @HyperliquidX volume in every month of 2027. @chameleon_jeff wears the suit so the conference crowd sends us more.

@BlackRock filed PBIT on Monday, a Bitcoin ETF with a 10% floor. We pulled it apart because we run a Bitcoin yield vault and wanted to know what the biggest asset manager thinks retail buyers want from protection. Short version for anyone who doesn’t trade options on @DeriveXYZ: PBIT keeps about a third of Bitcoin’s move in both directions, loses money in most flat scenarios after fees, and the floor resets lower every month, so a slow bear market still took the structure down 28% in our backtest. hXXI keeps all of the Bitcoin move and adds a yield on top, paid in @HyperliquidX / @unitxyz BTC. Over the last twenty months that has been the better trade by a wide margin, and we have the numbers. PBIT uses three overlapping quarterly call spreads on IBIT: long the 90% strike, short a cap, remainder in bills. The cap is set wherever the sold call pays for the floor. At today’s 38% implied vol that comes out at about 13% a quarter. It is almost insensitive to vol (12% at 23 vol and 15% at 63) because T-bill carry does most of the funding. We checked the model against Calamos CBXJ, the closest live product (90% floor on IBIT with a year of history). CBXJ captured 34% of IBIT’s up days and 36% of its down days. hXXI is different. It is not forced to write calls on the full notional when the premium doesn’t cover it, and what it collects is retained in BTC. Net of fees the factsheet shows 3.9% a year in BTC, worst month -0.9%, 17 of 20 epochs positive, max drawdown 1.8% of the Bitcoin stack. In dollars since February 2025 (IBIT -19%): NEOS income fund -17%, Roundhill covered call -24%, Innovator floor -28%. Return per unit of volatility: hXXI is the best on the shelf, ahead of our PBIT replica, with the Calamos and Innovator floors last. Forward we ran 20,000 paths to December 2027 at today’s implied vol with zero drift. hXXI has the highest expected return (~5%) versus under 1% for PBIT and 0% for IBIT, and the best return per unit of risk (0.11 vs PBIT’s 0.04). PBIT does what it says in the tails: worst 5% of outcomes improve from -60% to -30%, best 5% fall from +80% to +35%. Twenty Bitcoin buffer ETFs hold $146M total against $66B in IBIT. The largest is $25M after a year. Option income funds hold $1.8B and every one trails $ibit. @JSeyff @EricBalchunas @choffstein correct us if we’re wrong, but this doesn’t sound like much demand: are IRAs confident just on BlackRock for these buffers? It’s not that complicated 😅 Twenty funds sell Bitcoin with the upside removed, on an overfitted backtest. We sell Bitcoin with more Bitcoin. Factsheet and epoch-by-epoch record in BTC terms: DM us.

@StaniKulechov, @luigidemeo be careful, we are coming HOT. Hot7 Epoch 1 filled its $1M cap on @base. We supply tokenized stocks on Aave and short the same names on @HyperliquidX, delta flat, earning USDC incentives plus funding while the momentum rank sets how much goes to the 1.3x structure. We will win with @aave.

Paper's devs bragged about extracting back and forth on multiple podcasts, framing it as a skill issue if you don't make money. This seems to have worked as designed. Unclear who at .hl supports this. Negative for anyone who believes in the 'house of all finance' thesis rather than a 'bucket shop for virgins'. We want to rebuild the financial system that is adversarial for billions of people, not a bunch of 20-year-olds stealing money from each other (fine to prove tech limits through gambling, but don't call this innovation 🙏).

BlackRock filed a simpler copy of hXXI as an ETF. PBIT is long $IBIT, long a put spread, and short a call to fund it. It matches JPM’s Hedged Equity fund, which rolls the 95/80 put spread and sells the 5% OTM call quarterly on ~$20B of S&P so the call premium pays for the protection. On $BTC at 35 vol (vs 15), a one-year 100/85 put spread costs ~6% of notional. Selling one call to fund it sets the strike near 130. Buyers get the first 15% downside covered and keep upside to ~+30% before fees and skew. The same SPX structure caps near +18%. Crypto vol makes the collar pay nearly double. This is the trade hXXI has run on-chain since 2025. Calls are written on only part of the notional, so most of the sleeve maintains BTC upside in spot during rallies plus delta hedging and RV trades. Current: $1.7M TVL, 4.41% APR in BTC terms since inception, outperforming the other BTC ETF in the market. Time to outperform Larry too.

TABLOID STORY HERE, SERIOUS STORY IN THE QUOTED POST EXCLUSIVE: Prediction markets golden couple @hosseeb and Sydney have SPLIT, and pals say the charm gap was 174x. Kalshi's ETH perp did a sizzling $539m a day on just $3.1m open interest in September. Kalshi insists it's real demand. @Polymarket raised at a whopping $21B and Kalshi lounges on $22B, so dinner dates were never the expensive part. Haseeb, whose Dragonfly co-led Polymarket's Series A, was spotted on Oct 3 laughing about it on @_choppingblock (40:24 Kalshi's perps volume, 44:17 how the rebates went awry). A source close to the pod said: "He laughed. Then he checked the @Polymarket secondary bid." Two people NOT laughing: Elizabeth Warren and Jamie Raskin. Raskin wrote the House version of the STOP Corrupt Bets Act; Warren co-sponsored the Senate one. It bans sports and election contracts, and at 90% odds of a Democratic House the pair are January's likely chairs. A volume story every insider already knew is now Exhibit A at the hearing, and Warren's staff won't need to dig: @icobeast posted it, 96.7% share chart and all. Then there's the cap table. About $500m of Polymarket's book is 1789 Capital, where Trump Jr. is a partner, and "Trump family ties to prediction markets" is line one of the Democrats' hit list. Sydney's MOVING ON. @Novig says first-time depositors are up a saucy 362% since her ad, so she's still got it after American Eagle. Shame it's a sports-only book and sports is written into the bill. Our call: the next Polymarket and Kalshi marks print well below $20B . @icobeast didn't break up Haseeb and Sydney, but he may have cost them both a lot of $$$.

Midterms in 15 days, from the D2 desk. @Kalshi has a Democratic sweep at 62%, and crypto has priced it: $COIN, the most policy-sensitive proxy in crypto, closed at $173 Friday, matching the $174 it fell to on Sep 15 when CLARITY died. Not priced is January, when Democrats get subpoenas and @SenWarren takes the Banking gavel. PRICED IN 1. The map. Kalshi: Democrats 90% for the House, 63% for the Senate, 62% for the sweep. A Republican sweep trades at 10%. The sweep gained 4 points in a month and none today. Republicans can lose two Senate seats and still hold it (WSJ). 2. CLARITY is dead until 2027. Cloture failed 49-50 on Sep 15; four Republicans voted no, zero Democrats voted yes. $COIN dropped 9% that day and has not moved since. 3. The Fed. Warsh hiked 25bp on Sep 16 to 3.75-4.00%, the first hike since 2023. Oct 28 prices another at roughly 1-in-3, six days before the vote. 4. Equities already rotated to the anti-Leopold bunker. Bloomberg factor monitor, one week: low volatility +12.5%, dividend yield +6.7%, growth -7.9%, momentum -6.3%. Crypto is a growth and momentum asset (in theory). Utilities are the momentum trade now and they do not even have a Discord. 5. The why. September CPI 3.7%, core 2.6%. Rural prices +4.0% vs city +3.6%, motor fuel +35% on the year, and rural states pick the Senate: Kansas, no Democratic senator since 1932, is a toss-up. That is 76 years before the Bitcoin whitepaper. Trump approval 33%, a record low. NOT PRICED 6. Subpoenas arrive in January. Democrats take a chamber at 90%; first named targets are Trump family crypto ties and prediction markets, and Warren is favorite for Senate Banking chair. Apple, Microsoft and Palantir are hiring Democratic lobbyists now. 7. Ohio is the tell. A Fairshake affiliate spent $40m in 2024 to remove Sherrod Brown, four-year Banking chair. New polls put Brown ahead of Husted. Fairshake holds $122m and 32 endorsements, all House, 19 Republicans and 13 Democrats. $40m bought the first movie; nobody budgeted for the sequel. Money in the House, risk in the Senate. 8. The arithmetic. CLARITY lost at 49 with a 53-seat Republican Senate; it needed 60, so it needed Democrats either way. A flip changes the chairs, not the math. Today's rules are SEC and CFTC actions; a Democratic Congress cannot repeal what was never legislated. 9. The odds on prediction-market legislation are, fittingly, odd. $750m has traded on the midterms at Kalshi and Polymarket; Warren wants a public hearing on the venues and the CFTC wants the contracts called swaps. @icobeast should list a refund contract for the VCs who bought the pico top 😂 @0x_ultra can code it for him. 10. The trade after the vote. A Democratic Congress against a hawkish Fed sets up spending and debt-ceiling fights in 2027 (Bloomberg). BTC trades the deficit, and the deficit gets decided there, not on Nov 3. Post-midterms, crypto equities carry the January risk and the Warren risk; the coin carries the Fed and the fiscal fight after. We find this out in January. One reason this epoch of Alpha strategies ends on January 15. We trade for what is not priced in. 🫡

As posted in May, the steady state for @papertrade_xyz is ZERO and the only question is the path (a function of onboarding the marginal sucker). A perp like Hyperliquid pays the winner from the loser's already-posted margin. Paper pays the winner from the next loser's margin that has not been posted yet. Queue debt only shrinks while losses beat wins. Paper's edge against BBO mid is 2% of forfeited margin plus the impact tax. Remove the mint and the only volume left is the volume that extracts. Their wins are the LP's losses, the queue grows without bound, and the back of it waits FOREVER. Full unlock changes who owns the $PAPER. It does not change who funds the queue. Community ownership here is a residual claim on a system that needs a continuous supply of new losers/suckers to pay the people already waiting. The last ones in are exit liquidity for @izebel_eth and friends. If you want max degeneracy, maybe gamble on SK Hynix. At worst you can upgrade to 128 GB RAM cheaply and run a @HyperliquidX node. Hyperliquid

tl;dr: We can confirm the crash started on @binance. SNDK sell print 21:21:59.39, HL IOC sweeps 80ms later, Binance did $21.9M of SNDK that minute vs $3.1M on @tradexyz, HL liquidations only at 21:28. The playbook, unchanged for years: leveraged knife catchers pile into Binance longs over Friday and Saturday on a thin weekend book. Someone cleans the book 10/10 style, no news required. Arbitrageurs carry the print to every venue within seconds, Hyperliquid included. Old news for our 30 Sep Space listeners, 21:24. A wolf may lose its fur but not its vice. Disclaimer: we got baited for d2HYPE on Binance $hype spot listing, so we are particularly salty towards @cz_binance and his absolutely unrelated market makers.

Pls do not call it a hidden HOT point season. 👀🙏 But… Hyperliquid

We have traded options for almost 20 years, from a multi-billion notional vol book at a multi-strat to about $500M notional on @DeriveXYZ since December 2023, when it was still Lyra. Binaries are one pan. Here is what the SPX surface cooked on 16 Oct (spot 7700) that a $1 YES/NO ticket cannot: Calendar: Monday ATM vol 9.2, December 13.9. Sell two days of gamma, own two months of vega. Skew: 20 Nov 90% put 24.2 vol, 110% call 12.5. A risk reversal owns the 11.8-point slope; a binary is one dot on it. Put spread, the Hot7 hedge: buy 20 Nov 90% at 24.2, sell 80% at 36.7. The leg we sell is 12 vol points richer than the one we buy. Gamma: 9.2 vol says Monday moves 0.58%. Hedge the straddle hourly, collect realized minus implied. Tail: 20 Nov 80% put, strike 6162, pays per point below with no ceiling. A binary pays $1 at minus 20% and $1 at minus 60%. Cheapest vol on the screen is 8.75, the 26 Oct 102.5% call. A binary cannot even order it. TL;DR: a binary is a one-dish restaurant, fine for a Tuesday. A surface is a full kitchen: 18 strikes by 40 expiries on this screen, and we eat there every day.
