OPEN-SOURCE SCRIPT

INDEX Dashboard + Round Number Magnet

132
This TradingView indicator plots a pre-market dealer map for SPX based on the levels described by @azrael_options.

It draws the daily expected-move envelope from a reference close and the ATM straddle (1σ budget), the halfway shelves, the reference/magnet level, and two user-defined gamma walls (typically the nearest heavy-OI round strikes). A light box highlights the session range so you can see at a glance whether price is trading inside dealer parameters or outside them.

Each morning you update four numbers: previous close (or cash-converted overnight ES reference), ATM straddle points, lower gamma wall, and upper gamma wall. The script then draws the ±1σ walls, ±0.5σ shelves, and gamma levels automatically. A close beyond the outer walls is treated as the session invalidation.

The overlay is meant to replace discretionary chart lines with the same coordinates used in the five-minute open routine: mark the gap, price the straddle as the day’s budget, plot the boundaries, and size to 1R against those fixed levels.
