Prices are SPX at the minute. Change is close minus open; close to close is against the previous finished session. The zero-gamma flip is the terminal's measured flip at the close, and "crossed" counts the minutes the tape changed sides of it. Gamma at the close is where the close sat against that flip. Events are the market calendar's high and medium impact rows; the line under an in-session event is what the book did in the fifteen minutes after it, from the day's own payload. Nothing here is a forecast; see the Terms.
