📉 GEX Flow
The GEX Flow page provides a real-time time-series view of gamma exposure (GEX) at individual strike prices. By default it filters for 0DTE contracts, showing you exactly how dealer gamma positioning shifts throughout the trading session. Each line represents a different strike, making it easy to spot momentum shifts, regime changes, and convergence patterns.
Understanding the Chart
The chart displays multiple colored lines, each tracking the total GEX at a specific strike price over time. Key features:
🔑 Key Takeaways
- Multi-line time-series — Each line is a different strike price. The top 7 most significant strikes (by average absolute GEX) are shown by default.
- Y-axis: Total GEX — Positive values indicate dealer long gamma (stabilizing); negative values indicate short gamma (destabilizing). Values are formatted in millions (M) or thousands (K).
- X-axis: Intraday time — Shows the evolution throughout the trading session in Eastern Time.
- Zero line — A horizontal line at Y=0 separates positive and negative gamma zones. Strikes crossing this line signal a local gamma regime shift.
- Interactive legend — Click on a strike in the legend to toggle its visibility. Useful for isolating specific strikes.
Toolbar Controls
| Control | Options | Description |
|---|---|---|
| Expiry Filter | 0DTE, 1DTE, 3DTE, 5DTE, Monthly, All | Filter which expiration dates contribute to the GEX calculations |
| Window | 1h, 2h, 4.5h, Full Day | How far back in time to show data |
| Strikes | 5, 7, 10 | Number of top strikes to display |
What to Look For
🔑 Key Takeaways
- Convergence — When multiple strike lines converge toward the same value, it often precedes a significant move. Dealers are becoming equally positioned across strikes.
- Divergence — Rapidly separating lines suggest strong directional gamma buildup. The dominant strike (highest absolute GEX) acts as a magnet for price.
- Zero crossings — A strike crossing from positive to negative GEX (or vice versa) signals a local regime shift at that level. Watch for the spot price near these strikes.
- King strike dominance — The strike with the largest absolute GEX is the 'king' — it exerts the most influence on price behavior. If the king strike shifts to a new level, expect the price magnet to shift too.
0DTE Significance
💡 0DTE options have the highest gamma sensitivity — their GEX changes rapidly as time decay accelerates. This makes the GEX Flow chart especially valuable for 0DTE, as you can watch gamma build and decay in near real-time. The chart auto-refreshes every 60 seconds to keep you current.
How to Use It
🔑 Key Takeaways
- Pre-market Setup — Open the page before the trading session to see how 0DTE gamma is distributed. Use the 'Full Day' window to see overnight positioning from previous session data.
- Active Trading — During market hours, use the 1h or 2h window to focus on recent dynamics. Watch for convergence patterns and zero crossings near the current spot price.
- Combine With Profile — Use GEX Flow alongside the GEX Profile page for a complete picture: Profile shows the current snapshot distribution, while Flow shows how it evolves over time.
