See where market makers are positioned before you take the trade.

Every day, dealer positioning builds up at specific strikes on SPX and SPY. Those levels influence where price can bounce off, accelerate, and pin. Most retail traders never see them.

This puts them on your chart, updated every trading day.

What you get:

• SPX Ranked Walls: Strike concentrations 1 through 20 by open interest. Wall 1 is heaviest, and each fades by rank so hierarchy reads at a glance.

• SPX Call Wall and Put Wall: The heaviest call and put gamma strikes.

• 0DTE Gamma Flip: Where dealer gamma flips sign on today's expiration. Shapes intraday hedging, drives the regime table.

• Gamma Flip: The same boundary across the full chain. Slower structural context.

• SPX Expected Move: The 1D range from options data, drawn as a band.

• SPX Gamma Peaks: Where hedging most amplifies moves, and where it dampens them.

• SPY Walls, Gamma Flip, Call and Put Wall: A second chain on the same chart. Where SPX and SPY agree, the level is worth respecting. Where they diverge, you know before you take the trade.

• SPY Dark Pool: Off-exchange prices with significant transacted volume.

• Spot Price, Max Pain, and a Gamma Regime Table

Levels at the same price merge into one labeled line instead of stacking. Every level type has its own toggle, color, width, and style.

Calculated from SPX and SPY options data, plotted on ES.
