Market Structure

Put/Call Walls

By Aigars VolRadar·Mar 11, 2026

Price levels with concentrated options open interest that can act as support (put walls) or resistance (call walls) due to dealer hedging flows.

⚡ KEY TAKEAWAY: Sell put strikes near or below put walls for extra support. Avoid selling calls near call walls.

Term Structure

Contango = normal, good for sellers. Backwardation = market stress, reduce position size or wait.

Contango

Normal state = green light for sellers. VIX/VIX3M below 0.9 means term structure strongly supports premium selling.

Backwardation

Market is pricing more fear now than later. Reduce size, tighten stops, or sit out until contango returns.

VIX (Volatility Index)

VIX 15–25 is the sweet spot for premium sellers — enough fear for rich premiums, not enough for gap risk.
