Option Walls and Support/Resistance
Option walls are price levels with significant open interest concentration that create natural support and resistance levels through market maker hedging dynamics.
Understanding Option Walls
Option walls emerge from the interaction between options open interest and market maker hedging behavior. These levels often act as price magnets or barriers.
Types of Option Walls
Call Walls (Resistance)
Call walls form at strikes with high call open interest above the current price.
Formation Process:
- Traders buy calls at specific strikes
- Market makers sell these calls (short position)
- Market makers hedge by buying stock
- As price approaches strike, hedging intensifies
Market Dynamics:
- Market makers are short gamma at these strikes
- Must sell stock on approach (resistance)
- Creates “pinning” effect near expiration
- Stronger with higher open interest
Trading Implications:
- Natural resistance levels
- Profit targets for long positions
- Entry points for short positions
- Volatility compression zones
Put Walls (Support)
Put walls form at strikes with high put open interest below the current price.
Formation Process:
- Traders buy puts for protection
- Market makers sell these puts
- Market makers hedge by selling stock
- As price declines, buying increases
Market Dynamics:
- Market makers buy on approach
- Creates support at strike
- Bounce probability increases
- Acts as downside cushion
Trading Implications:
- Natural support levels
- Entry points for longs
- Stop loss guidance
- Reversal zones

Best Practices
- Confirm with price action - Walls alone aren’t enough
- Consider time to expiration - Walls strengthen near expiry
- Watch for catalyst events - Can override wall dynamics
- Use multiple timeframes - Weekly and monthly walls
- Respect major walls - Higher probability levels
Common Mistakes
- Fighting major walls - Respect institutional positioning
- Ignoring wall breaks - Momentum can accelerate
- Over-relying on walls - Combine with other analysis
- Missing wall changes - Dynamic repositioning occurs
- Poor timing - Walls matter most near expiration
Important Note: Option walls are dynamic and can change with market conditions. While they provide valuable support and resistance levels, they should be used in conjunction with other technical and fundamental analysis for trading decisions.
