Module 3 · 0DTE & Using Levels
Using Published Levels
Call wall, put wall, zero-gamma — a practical workflow.
In this lesson you'll
- Identify the regime from the levels
- Mark the rails (call/put walls) and the pivot
- Pick tactics by regime
Many independent traders build a workflow around vendor levels (e.g., SpotGamma, Menthor Q):
- Identify the regime: is price above the Vol Trigger / zero-gamma (presumed long-gamma → stable, fade extremes) or below (presumed short-gamma → volatile, respect momentum)?
- Mark the rails: treat the call wall as the day's ceiling and the put wall as the floor; the key gamma level / HVL (most total gamma) is a potential pin / pivot.
- Pick tactics by regime: in positive gamma, fading toward the walls is the common setup; in negative gamma, avoid mean-reversion and respect trend continuation.
Key takeaways
- Step 1: regime from above/below the Vol Trigger / zero-gamma.
- Step 2: call wall = ceiling, put wall = floor, key gamma level = pin/pivot.
- Step 3: positive gamma → fade the rails; negative gamma → respect trend.
- Levels recompute and fail on news — read, don't predict.

Why that's off: Chasing breakouts fits the NEGATIVE-gamma (trending) regime.
Why that's off: The regime informs tactics; it doesn't forbid trading.
Why that's off: The call wall is the ceiling to fade, not to buy into.
In positive gamma the market mean-reverts, so the common play is fading the rails — selling toward the call wall, buying toward the put wall, expecting rotation.
Why that's off: They're range rails / references, not just triggers.
Why that's off: They're a range, not the precise close.
Why that's off: They're central references in the workflow.
The call wall acts as the expected ceiling and the put wall as the floor — the rails between which a positive-gamma day tends to rotate.
