Know your room to move — New GEX Wall Signals in the Scanner
Three new columns show where the gamma walls sit and how much room price has to run.
Hi everyone,
We just shipped three additions to the Scanner that make dealer-gamma levels readable at a glance.
Put Wall % / Call Wall %
Signed distance (Wall strike price) from the current price to the strongest put and call gamma strikes. Put walls usually sit below (negative) as support; call walls above (positive) as resistance. A near wall during a matching surge is the sharpest read: a close call wall on a call surge = capped upside; a close put wall on a put surge = a likely floor.
E.g., PLD is at a put wall around $140, and a call wall is 7% higher; thus, with a call surge, it has room to run.
You can see the details when you click on the ticker, where the call and put walls are, but now we've made it easy to scan for those names in the scanner.
Wall Band
A tiny chart in every row. The tick marks the current price; the red bar is the put wall, and the green bar is the call wall, both placed by distance. Bar height shows wall strength (weak → dominant), and the gray line spans the put-to-call range — your room to move. A ⫽ break means a wall sits beyond ±10%.
When you hover over the Wall Band with your cursor, you can also see all the details.
Custom columns + sort
Use the new Columns button to show/hide fields, and click any header to sort. Example: filter to mega caps, then sort by Call Wall % descending to surface names with the most upside room to their resistance.
