Market makers hedge their options inventory by continuously trading the underlying to stay delta-neutral — and because that hedging concentrates around key strikes, it creates real support and resistance. Here’s the mechanism behind the levels.
The hedging loop
A market maker who’s net short calls at a strike gets longer delta as price rises toward it, so they sell the underlying to stay neutral, which caps price near that strike (a call wall). Net short puts below get shorter delta as price falls, so they buy, supporting price (a put wall). This mechanical hedging is why heavy strikes act as levels.
Regime changes everything
Whether hedging damps or amplifies depends on long vs short gamma. In positive gamma, hedging is stabilizing (levels hold, price pins); in negative gamma it’s destabilizing (levels break, moves accelerate). Layer in charm (time) and vanna (vol) hedging, and you have the full flow picture.
A level holds not because traders “remember” it, but because a market maker is mechanically forced to trade against price there to stay hedged. Structure with a reason.
What it means for a scalper
Understanding MM hedging is what separates trading dealer structure from trading arbitrary lines — the levels have a mechanical cause. That’s the core of NoVo’s dealer map: it computes where hedging concentrates so you can trade the footprint, and alongside it NoVo now reads the raw order flow in-house off the live tape — sweeps & block prints per ticker on the Analyst dashboard. Still structure, not signals — where price may react, not a prediction.
