A dealer map describes hedging obligation. It does not describe everything else that trades, and everything else is usually larger — which is the size argument in crypto gamma is smaller than it looks.
So price moving through a wall is ordinary. What matters is distinguishing the reasons.
Four reasons a level fails
Flow simply exceeded it. The most common. Dealer hedging leaned against the move and was outweighed. Nothing was wrong with the map; the map was never a promise.
The wall was an artefact. Stale open interest at a strike nobody has traded in weeks, entering the calculation at full weight — the hazard in reading a thin options book.
The positioning assumption was wrong. Every map infers which side dealers are on. If the customers-buy prior fails, the sign is inverted and the level was expected to act in the opposite direction — two ways to infer dealer positioning.
You read the wrong book. For BTC and ETH there are two, and a level from the ETF book plotted against coin spot is correct arithmetic on the wrong instrument.
How to tell them apart
Check the open interest behind the level and whether the strike has traded recently. Check which book the number came from. If both survive, the level was real and got overwhelmed — and that is a fact about flow, not a reason to distrust the map.
The disagreement worth acting on
Price holding at a level the map says has nothing behind it. That is a genuine anomaly, and it usually means something the options book cannot see — liquidation structure, or spot interest with no derivatives expression at all.
