Strike Profile
Exposure at every strike for the chosen ticker and expiry, built on open interest.
What it shows
A bar per strike for GEX, CEX, VEX, DEX, OI or VOL, horizontal by default, with headline figures NET, FLIP, C WALL and P WALL. With '0DTE only' off, the next three expiries appear as heat columns. Hovering a strike lists Net GEX, Call / Put GEX, Net DEX, and OI, volume and premium for calls and puts.
What it is built from
Exposure at every strike, with calls counted as positive and puts as negative. Computed from data consolidated across every US options exchange: open interest and volume.
Reading
How to read it
- The longest positive bar is the C WALL; the longest negative bar is the P WALL.
- FLIP is where net gamma, added up strike by strike, crosses zero.
- Net | C/P pulls each bar into its call and put legs; the two legs always add back to the net bar.
- An 'OI updating' tag means today's open interest is still arriving.

Good to know
- A long positive bar marks heavy call open interest near that strike; a long negative bar, heavy put open interest.
- Open interest refreshes overnight and 'holds still through the session' (the product's own tooltip); intraday the bars move with price, time and implied volatility.
- Flip and wall marks are drawn on the GEX metric.
