GEX/VEX Confluence
Confluence matrix, step-by-step check process, and multi-index agreement

🔀 Why Confluence Matters

GEX and VEX measure two different forces acting on the same market:

  • GEX = dealer hedging driven by price movement (gamma)
  • VEX = dealer hedging driven by IV movement (vanna)

When both forces align at the same strike price, the resulting support or resistance is significantly stronger than either alone. When they oppose each other, the outcome becomes uncertain and IV-dependent.

📊 Confluence Matrix

At a Single Strike Price

GEXVEXConfluenceInterpretation
++✅ Strong AgreementStrongest support/pin level. GEX stabilizes on price moves; VEX adds buying support as IV falls. Highest probability reversal zone.
−−✅ Strong AgreementMost dangerous zone. GEX amplifies price moves; rising IV triggers VEX selling. Double acceleration — avoid or trade momentum only.
+−⚠️ OpposingGEX pins price, but VEX creates headwind for rallies. May produce "sticky resistance" where moves stall.
−+⚠️ OpposingGEX amplifies price moves, but VEX may cushion if IV peaks and reverses. Potential reversal zone but low confidence. IV direction is the deciding factor.

At the NET Level

NET GEXNET VEXMarket Character
++Calm. Low vol. Pinned. IV compression supports price. Best environment for range trading and premium selling.
+−Pinned with bearish lean. Rallies face VEX headwind. Range-bound but skewed.
−+Conflicted. Volatile price action, but IV direction determines whether VEX helps or hurts. Most sensitive to IV regime.
−−Maximum volatility. Trend days. Cascading moves. Worst environment for mean-reversion.

🔍 How to Run a Confluence Check

  1. Open the GEX heatmap. Identify the 3–5 most significant nodes (largest absolute values). Note their strikes, values, and signs.
  2. Switch to VEX. Look at the same strikes. Note each VEX value and sign.
  3. Build your confluence table for each major strike:

$6,550−$400.0M−$18.5M✅ Both −Danger zone
$6,400−$1.3B+$102.9M⚠️ OpposingIV-dependent

Prioritize confluent levels. Same-sign strikes are your highest-conviction setups. Opposing-sign strikes require additional context — primarily IV direction.

🎯 Trading Confluent Levels

Strong Positive Confluence (+GEX / +VEX)

What to expect:

  • Price approaches smoothly (positive GEX = low volatility interaction)
  • Strong reversal probability, especially on first touch
  • IV typically stabilizes or falls at these levels, reinforcing VEX buying

How to trade:

  • Fade the approach — enter reversal positions as price reaches the zone
  • Tighter stops are appropriate — if this level breaks, the thesis is invalidated

Strong Negative Confluence (−GEX / −VEX)

What to expect:

  • Price enters violently (negative GEX = high volatility interaction)
  • Overshoot is likely before any reversal
  • IV typically rises at these levels, compounding VEX selling pressure

How to trade:

  • Do not fade. This is momentum territory
  • If already positioned in the direction of the move, consider adding
  • If caught on the wrong side, exit — don't hope for reversal
  • If a reversal does occur, it will be violent and preceded by an overshoot — wait for confirmation

Opposing Confluence

What to expect: Uncertain outcome — one force stabilizes, the other amplifies. IV direction becomes the deciding variable.

How to trade:

  • Reduce position size
  • Wait for price action confirmation before committing
  • Monitor IV in real-time — is it expanding or compressing?
  • If in doubt, stand aside

🧭 Multi-Index Confluence (US Equities)

For US equity indices, the highest-probability setups occur when SPX, SPY, and QQQ heatmaps all agree.

Why Multi-Index Matters

  • A strong floor on SPX can prevent a rug pull on QQQ
  • A major ceiling on SPY can cap rallies on SPX
  • The indices influence each other dynamically
"Would my thesis still hold if I took this trade on the other two indices instead?"

Cross-Index Conflict Examples

SPX shows large upside Anchor, but SPY shows large downside Anchor: Conflicting magnets between indices. Expect choppy, directionless price action. Avoid directional trades until one signal clears.

QQQ has void below, but SPX has strong floor: SPX floor may limit the downside move even through QQQ's void. The floor on SPX acts as a "brake" for the broader market.

📚 Key Takeaways

  • Same-sign confluence (GEX and VEX agreeing) = highest conviction levels
  • Both positive = strong pin/support; Both negative = danger zone
  • Opposing confluence = uncertain; IV direction is the tiebreaker
  • Always build a confluence table for your top 3–5 nodes before trading
  • For US equities, SPX/SPY/QQQ must agree for highest-probability setups
  • When signals conflict across indices, standing aside is a valid trade
