How it reads a session
Thursday, October 29, 2026, start to finish.
A mega-cap earnings day in an earnings-heavy week, the day after an FOMC decision and the session before month-end. Here is what SPX Zero showed, and what the tape did.

The session · as it ran
Trend moves, logged live
Each trend move was added to the Day Desk as it formed, refreshed through the session, with the day's biggest move marked.
The morning chopped, inside the window the calendar had marked and the premarket read had pointed to.
One session proves nothing on its own. The method below says what the score can and can't see.
Method
How the score is built, and where it stops.
Calendar only
The score comes from scheduled events alone: expiries, earnings windows, economic releases, Fed days, holidays and rebalances. Price never moves the score.
Compounding weights
Each session starts at 100, and each factor removes its share of what is left, so stacked days sink but stay ranked against each other.
Two modes
Trend mode weighs friction for intraday trends: pinning, rotation, thin books. Risk mode weighs scheduled event and gap risk.
Calibrated, with limits
Weights were checked against 31 sessions of SPX price data, Sep 17 to Oct 29, 2026. The calendar can't see unscheduled news, and about half of clear-calendar days in that sample still chopped.
Trend moves
Measured from intraday SPX prices and shown alongside the score. They record what the session did; the score never uses them.
Sources
FOMC dates from the Federal Reserve, CPI, PPI and jobs dates from the BLS, checked weekly. Holidays, OPEX and VIX expiry are computed from exchange rules.
