Regime check first: VIX at 18 and creeping up 3.7% over five days while SPY grinds +0.5% — that's not a clean low-vol grind anymore, it's the early texture of vol expansion under a still-rising tape. Today's tape is also telling: utilities, REITs, and financials leading down while tech leads up is a rates-up rotation, not a risk-on broadening. We're 14 days past FOMC with 35 to go, so we're in the no-man's-land where macro catalysts are sparse but positioning shifts dominate. Fine backdrop for selective premium structures, but not a green light for anything. On the candidate itself: I can't evaluate this trade. Probability of profit is 0.00, EV is $0.00, max loss is $0.00, capital required is $0.00. Those aren't conservative estimates — those are missing data. A put diagonal selling the June 695 and buying the July 710 on QQQ is a real structure (debit, bearish-to-neutral, long vega, positive theta on the back month relative to the front), but I have no pricing, no greeks, no breakeven. I'm being asked to commit capital to a structure where the system can't even tell me what it costs. Worst case is unknowable from the inputs, and that alone is disqualifying. Structurally, a put diagonal's worst case is the net debit paid if the short expires worthless and the long collapses, or a gap below the short strike before roll — could easily be $300-600 on a 15-wide QQQ diagonal. On a $27.7K book that's 1-2% per position, tolerable in isolation, but I already have four positions on and three of them (TMO bear call, IWM put calendar, ASML bear call) are bearish/short-vol-adjacent. Adding a QQQ bearish diagonal makes this a five-position book that's really one concentrated bet: short the tape, long vol-of-vol. That correlation is the actual risk, not the line-item max loss. Confidence this is a pass: 90. The book is already tilted the way this trade tilts, the pricing data is absent, and the regime is exactly the kind of slow vol-creep environment where short-dated short premium gets repriced violently. I've passed 20 in a row and that's fine — selectivity is the job.
