Reading the market regime before prices move
Reading the market regime before prices move
Every number here is computed from the traded MCD options chain. The call wall is where dealer hedging accumulates above spot and caps upside, the put wall is its mirror below, and the gamma flip is the level where hedging stops damping moves and starts amplifying them.

السعرُ 255.69 يقع تحت نقطةِ الانقلاب 264.15 بفارق 3.20٪، عمقٌ في المنطقة السالبة. Dealer hedging here sells into weakness and buys into strength, meaning it **amplifies** what happens instead of absorbing it. Returning to a braking regime requires a rally beyond 3.2%. Price is pinned to the put wall at 255.00: this level acts as a floor while positioning holds, and breaking it opens a wider range than its proximity suggests.
أكبرُ تجمّعٍ لعقود الشراء عند 270.00 (5.60% from price)، ولعقود البيع عند 255.00 (-0.27% from price)، والمسافةُ بينهما 5.88٪، a **wide** range. That does not imply a move is coming, only that the walls are far enough apart not to confine MCD during the session, so flow leads rather than hedging.
صافي تعرّض الغاما لـMCD يبلغ −38.41 مليون، وهو حجمٌ محدود. Hedging for a 1% move is about 150,203 shares. In this range hedging stays secondary to the stock's own flow, so the levels below should not be asked to carry more than they can.
and this reading is built on 614 contracts in the chain.
Over the last 27 days of tracking (299 archived snapshots), MCD stayed above the gamma flip in 49% of readings، وتنقّلت نقطةُ الانقلاب نفسُها بين 260.74 و271.18، أي بنطاق 4.00٪، وهو ما يعني أنّ the level moves with the market and does not serve as a fixed reference across days، and net exposure today is above the period average (−7.32 مليون).
