# Chain Profile

Net gamma of the whole chain at each strike, as one profile, with the flip, call wall and put wall.

**Chain Profile** collapses every expiry in the window (90 days by default)
into one bar per strike, so you see the shape of the whole chain at a glance.
The header shows the net chain gamma and the flip. Green bars are strikes where
dealers are long gamma, red where they are short.

## Practical application

![Chain Profile widget, illustrative example: one dominant call strike above price in positive gamma](https://q-bitf.com/docs-img/chain-profile.png "Illustrative example data, not a real session. NQ, 90-day window by open interest: net chain gamma +2.2B, flip 26,929, spot 27,075, call wall 27,250 at about +2.4B.")

**Reading it.** Net chain gamma is **+2.2B** and the flip is at 26,929, about
150 points under spot. One bar dominates the chart: the call wall at 27,250,
at about +2.4B, roughly three times the next largest strike (27,150, about
+0.8B). Below price, the largest red bar is the put wall at 26,600, about
-0.9B, with 26,800 (about -0.5B) closer to price.

**What it means.** The book is long gamma near price, and most of it sits at a
single strike 175 points above. That strike is where dealer hedging is
heaviest, so it is the most likely place for a rally to stall or for price to
gravitate into an expiry.

**How to use it.**

- **One dominant green strike above price:** treat it as a target and a
  ceiling. Longs can aim for it; fresh longs right under it have little room.
- **Spot between the flip and the big strike:** dips toward the flip are more
  likely to be bought while the regime holds.
- **A balanced profile with no standout bar:** less pull toward any one
  price; rely on the flip and the walls instead.
- Compare the **0DTE** and **1DTE** windows in **Details** to see whether the
  short-dated book agrees with the 90-day picture.
