The 0 GEX program evaluates short-term SPX support and resistance opportunities as Net GEX expands away from zero and later contracts toward it. This expansion and contraction cycle provides the context for evaluating a potential price reaction around seller-defined levels.
The process begins with an initial Net GEX expansion. As exposure contracts toward zero, the program enters an evaluation window to assess sold-put support or sold-call resistance. A qualified opportunity becomes active when the program’s conditions are met. The lifecycle distinguishes the developing setup from an active opportunity.
Sold-put activity can help identify potential support, while sold-call activity can help identify potential resistance. The Flow Map allows traders to inspect the activity behind those levels and its location relative to SPX. The levels are reaction references rather than guaranteed barriers.
Market Intelligence identifies the current stage of the 0 GEX lifecycle, the supporting observations, and the relevant reaction level. Its updates help traders follow the transition from expansion through evaluation to a qualified active opportunity.
GEX Phase Delta Flow displays Net GEX alongside directional option flow through time. It helps traders examine how pressure develops during the expansion and contraction cycle and whether that pressure begins to support or challenge the anticipated price response.
The Delta Flow Meter provides broader directional-pressure context across the option chain. As SPX approaches a reaction level, traders can assess whether pressure is building, fading, or reversing and whether those changes support the developing setup.
No. Price may approach support under bearish pressure or resistance under bullish pressure. Supporting evidence can emerge through a change in that pressure near the reaction zone—for example, bearish pressure fading near support or bullish pressure weakening near resistance. Flow does not need to be aligned throughout the approach for a potential reaction to develop.
Read the Market Intelligence assessment, verify the seller-defined level on the Flow Map, and examine gamma conditions and directional pressure using the supporting tools. The key is whether price behavior and changing flow near the level support the expected reaction or begin to conflict with it. An active program opportunity still requires independent evaluation and risk management.
