Regime check first: VIX at 18 and trending up 3.7% over five days, SPY grinding modestly higher, and the tape today shows defensive sectors (utilities, REITs, financials) getting hit while tech leads. That's a mildly risk-on rotation underneath rising vol — not the clean low-vol grind that calendars want. We're 35 days from the next FOMC, so the back month of any calendar will straddle that event, which is exactly the kind of vol-expansion catalyst that breaks short-front/long-back theta structures when the front decays slower than expected and the back doesn't bid as much as you hoped. More importantly, the candidate itself is broken on the math. EV is negative $18 on a max loss of $20 — the scoring engine is telling me this trade loses money in expectation and the worst case is essentially the whole ticket. P_profit is reported as 0.00, which either means the model can't price it or the structure is genuinely upside-down. Either way, I don't open trades where the headline expected value is negative. There's no edge to discuss; the question answers itself. Worst case is $20 on $27.7K cash — 0.07%, trivially survivable in isolation. But that's not the right frame. The portfolio already holds an IWM put_calendar opened yesterday, so adding a second calendar is doubling down on a strategy class I have zero track record in, in a regime where vol is rising into a Fed meeting. Correlation at the strategy level matters more than the dollar size of any one ticket. And LYFT at a $14 strike is a low-priced underlying where a single news headline can move the stock 8-10% and wreck the calendar's vega structure. Confidence this is a pass: 95. The negative EV alone is disqualifying; the regime and the existing calendar exposure are confirmation, not the core reason.
