Per-symbol gamma walls

Lesson 13 of 15 in Options & GEX. Markets grade, 75 XP. Free to read, mission runs live in the terminal.

» Each stock has gamma 'walls' — strikes where dealer hedging clusters.

» Price often magnets toward or stalls at these walls. Real levels, not lines you drew.

» Knowing the walls tells you where a move might stall or break.

» Open SPY's per-symbol GEX and find its gamma walls.

Watching a concept is not the same as running it, so every Academy lesson ships with a live mission inside the Tapeboard terminal. This one runs on the GEX panel (/gex/SPY). Reading is free; running missions takes a free account.
