Why price stalled at the call wall
Dealers hedge, and that moves price.
Standard models assume customers sell calls against stock, so dealers end up long those calls. A call wall forms at the strike with heavy call open interest. As price rises into it, dealers sell stock to stay neutral, adding supply exactly where buyers are pushing.
Price stalls at the CALL WALL.
The rally slows and pins near the dominant call strike. On major indexes these levels often hold into expiration as dealer selling meets fresh buyers.
How long the stall lasts.
The stall can be minutes or the whole session. If price absorbs the dealer supply and pushes through, the level is broken and momentum often accelerates. Watching the reaction at the level tells you more than the level itself.

Show the answer
C. It stalls or pins near the level. Dealer hedging adds supply near large call strikes. That supply tends to slow price down and can hold it for hours.
