SPX Gamma Active Trader Tools: GEX Phase Delta Flow

What is SPX Gamma GEX Phase Delta Flow?

GEX Phase Delta Flow combines Net GEX and directional option flow in a single chart. It helps traders examine how gamma conditions and bullish or bearish pressure develop together through time.

How does the chart display Net GEX and Delta flow?

The widget plots Net GEX through time and overlays Delta-flow bubbles at the corresponding observations. This allows traders to compare changes in gamma exposure with the directional activity occurring alongside them.

What do positive and negative Net GEX readings show?

The sign identifies whether measured Net GEX is above or below zero. Movement away from zero shows expansion in its magnitude, while movement toward zero shows contraction. These changes provide gamma-phase context rather than a standalone forecast of SPX direction.

What do the Delta-flow bubbles represent?

Bubble size represents volume, while bubble color identifies bullish or bearish Delta flow. Reading both helps traders distinguish the direction of the observation from the amount of activity behind it.

How does the volume threshold affect the display?

The threshold filters which observations appear. Raising it removes smaller-volume bubbles and focuses the chart on larger activity. Lowering it reveals more observations. Activity below the selected threshold is filtered from view, not absent from the market.

How is GEX Phase Delta Flow used in the 0 GEX layout?

Market Intelligence identifies the stage of the 0 GEX opportunity, while the Flow Map shows the seller-defined support or resistance being evaluated. GEX Phase Delta Flow adds directional-flow history throughout the gamma expansion and contraction cycle, helping traders assess how pressure changes as the setup develops.

How is the widget used in the End of Day Range layout?

It provides gamma-phase and directional-flow context around the seller-defined boundaries displayed in EOD Range Insights. Used alongside the GEX Trend Monitor, it helps traders evaluate whether developing pressure supports containment or is beginning to challenge one side of the range.

Does a single bubble or a move through zero confirm an opportunity?

No. The important question is whether gamma conditions, directional flow, and price behavior support the same interpretation. Conflicting evidence or changing pressure should prompt reassessment rather than treating an isolated observation as confirmation.
