A Houthi drone strike on Saudi Aramco's Shaybah oil field cracked crude above $110 overnight, and disappointing read-throughs from Tesla's capex pullback and Lam Research's wide guidance band broke the AI trade's momentum just as futures were set to extend Wednesday's gains.
Closes: SPX +0.58% / NDX +1.13% / RUT +0.27% / DJX +0.69%. The drift+skew lean spreads 50–64% down across the four, tracking each index’s own read rather than a single pinned number. The live catalyst: Houthi strike spikes crude; TSLA capex cut, LRCX wide guidance.

Enter any two price levels — your expiration breakevens, T+0 breakevens, or the support/resistance you’d adjust at — and this returns the odds price stays between them. Work in the index or, with the Instrument switch, in its ETF’s price.
It prices the implied move from the index’s own option-market volatility, tilts it for put skew (downside tails are fatter than upside) and for the directional lean in tonight’s read, then measures where your two levels fall on that distribution. The horizon sets the vol it uses: Rest of day prices off each index’s own 1-day option-implied IV and shrinks as the session runs down; Overnight, 1-Week and Expiration use its 30-day option-implied IV. Expiration counts the trading sessions between now and the date you pick — weekends and market holidays do not count — and stretches the move by the square root of that number. Note it will read wider than Overnight for tomorrow: overnight prices only the gap, a fraction of a session’s variance, while one session at Expiration is a whole trading day. The VIX, VXN, RVX, VXD readings shown in the banner are the CBOE index spots, printed for reference — they run a few points above each index’s own at-the-money IV because they price a wider strip of out-of-the-money options, which is why they never match the band vol exactly.
Touch odds are the headline. “Never touches either” asks whether price stays inside your range the whole way — not merely where it finishes. That matters because a level that gets tagged intraday has already forced your decision, even if price closes back inside. Closing odds flatter a range; touch odds tell you what you’ll actually live through.
The current-vol box is a what-if on volatility — type an actual reading, not a point change, and the bands re-scale. What it asks for depends on the horizon. Overnight and 1-week pre-fill with the vol-index spot captured at the run (VIX for SPX); type the current reading and the bands shift with it. Rest of day asks for the 1-day reading — where no live VIX1D was captured the field starts empty; chart it and type the current value, and it sizes the intraday bands directly. Until then, rest-of-day uses that index’s own 1-day IV.
⚠ These are estimates, and they age. Volatility, skew and the directional lean are frozen at the ~9:00 AM ET run that produced this page — only your inputs and the clock keep updating. Run this during the session that follows and it’s working from a live picture. Run it a day later, or after a gap or a volatility spike, and the inputs behind it are stale even though the numbers still move. Check back for the next report for anything current. Options-implied probabilities are a description of what the market is pricing, not a forecast — and nothing here accounts for your position size, spreads or fills.

The next open is Thursday’s (gap into today’s open). Here’s where the gap gets made:
| When | Event | Why it matters for the gap |
|---|---|---|
| Now · live | Houthi strike spikes crude; TSLA capex cut, LRCX wide guidance | The identified driver for the current tape. |
| Latest closes | Cash session | SPX +0.58% / NDX +1.13% / RUT +0.27% / DJX +0.69%. SPX 30-day implied vol 13.20. |
| Into Thursday’s open | Futures + Asia/Europe trade | First live read on the overnight tone. Watch NDX ~29,500 and SPX ~7,725 at the open. |
| Friday, Oct 23 — before open | American Express (AXP) Q3 2026 earnings | Consumer credit and spending bellwether; AXP guidance on delinquencies or spend deceleration would either confirm or counter the more cautious AAII sentiment reading seen this week. |
| Tuesday–Wednesday, Oct 27–28 | FOMC two-day meeting; rate decision statement 2:00 PM ET, Oct 28 | Brent above $110 adds a live inflation wildcard to an already uncertain rate path — a hawkish tilt or upward revision to inflation language would compound today's equity damage and delay any expected pivot. |
| Wednesday, Oct 28 — after close (confirmed) | Microsoft (MSFT) Q1 FY2027 earnings | Azure cloud growth and AI capex commentary will either reaffirm or further erode the AI-spend narrative that Lam Research and Tesla have already cracked this week; the most important single print for NDX direction into month-end. |
| Wednesday, Oct 28 — after close (confirmed) | Alphabet (GOOGL) Q3 2026 earnings; reports same evening as MSFT and FOMC | Google Cloud growth and AI monetization results land within hours of the Fed decision and MSFT — a rare triple-event session; NDX volatility on Oct 29 open could be outsized in either direction. |
