Prices where options positioning concentrates, so price slows or reverses there more than elsewhere. Finviro's term: “Key Price Levels”.
What these levels are
Key price levels (Key Price Levels) are the prices where expected market behavior changes: gamma walls and the flip point, reference highs and lows, large open-interest levels, and institutional accumulation zones. A map of the places where “something happens.”
Why they work at all
Two reasons working together: mechanical, at dense gamma levels automatic hedging intensifies so price slows or bounces, and behavioral, thousands of eyes on the same level make orders pile up there and the prophecy fulfills itself. A level that combines both weighs more than a single chart-pattern level.
How to use them correctly
Decision zones, not automatic execution lines: you watch the reaction there. A bounce on volume confirms respect, and a break on volume flips the role (a broken ceiling becomes a floor). Entering near them, not in the middle of the gap between them, gives a sensible close stop instead of an arbitrary distant one.
Hypothetical example
A stock nearing a level where a heavy put wall meets a prior reference low: a first-class decision zone. A bounce off it on volume offers an entry with a stop just beneath, and a clean break shows the structure changed, with a cheap exit because the stop is close.
Common mistake
Keeping last week's map: gamma levels change with every shift in open interest and vanish with every expiration. Structural levels are a living thing that gets updated, not lines drawn once and treated as sacred.
Where to see it on the platform
The gamma dashboard draws them updated for each symbol, and the symbol card gathers structure and reference levels in one readable table.
