“Where are the walls” is the second question most traders put to a markets Super Intelligence, straight after the flip. The first half of the answer is simple. The second half is a list of things the SI should decline to say, and that list is the more useful part.
What a wall is
A call wall and a put wall are strikes where dealer hedging is concentrated, estimated from options open interest. NoVo maps both on SPY, QQQ and IWM. The mechanics are in gamma walls, explained. For the question at hand, one fact is enough. A wall marks where hedging is heavy. It is a description of the book.
What a good answer contains
It names each wall and gives its strike. It gives the distance from the last price to each one, so you can see which is nearer. It says where price sits between them: close to the call wall, close to the put wall, or in the middle with room both ways.
It also gives the age. On Trader Pro the dealer read runs on a 5-minute cycle, and on Trader Max it is live. A wall quoted without its age is half an answer.
What he will not say
Dr. NoVo, NoVo’s Financial Markets SI, will not say that price stops at a wall. Hedging concentrated at a strike can slow a move. It can also be run through. Which one happens is not in the data.
He will not call a wall support or resistance. Those words come from price history, and a wall comes from positioning. The difference is set out in walls are not support and resistance.
He will not say how long a wall lasts. Walls move as open interest changes and as contracts expire. A level that was the call wall this morning may sit at another strike by the afternoon, which is the subject of call wall migration.
He will not tell you what to do at one. That is a decision, and it needs your side of the screen.
The markets that have no walls
Ask for the walls on a stock perp or a stock token and the right answer is that there are none. Perps and stock tokens have no options book behind them, so they have no dealer gamma, no flip and no walls. A markets SI should correct the premise and offer what those markets do publish: funding, open interest, premium and supply.
A better second question
Once you have the two strikes, ask how they sit against the expected move. A wall inside the day’s expected range is a level price could plausibly reach today. A wall well outside it is background. That comparison is a reading, and the SI can make it. What a wall is and is not, in more detail, is in what a wall is and is not.
Where to see it
The walls are drawn on the Trader dashboard, with Dr. NoVo’s written reads beside them. Ask him where they are, then check the chart. He reads the same map you are looking at.
