Premarket Prep

Premarket Prep is the page you open at 8:00, not 9:31. It answers the three questions that decide how you trade the open: which gamma regime you are walking into, where the levels that matter sit, and what the overnight session already did to them. Everything on it is computed off the same live chain the GEX chart reads, so the board and your prep can never disagree.

The walls come with their own history: each key level carries where it sat at the prior close, so a wall that migrated 40 points overnight says so instead of looking like it was always there. Alongside them are the gamma profile and its distribution curve, the expected-range track, max pain, the 0DTE magnet, DEX and vanna totals, and the overnight ES high, low and prior RTH close.

It runs on every name in the picker — SPX plus the whole watchlist — with the same panels, computed from that ticker's own chain rather than a reduced board. When the bell rings you already know the map; and when the session is over, the Post-Market tab recaps what the day did with it.
