META call spread likely bought to open

At 10:13 ET, 11,754 Feb 19 780 calls and 11,754 Feb 19 950 calls traded together in one order on BEST, the same size on every leg: one trader, one decision.

Open interest before the session: Feb 19 780 call 918 with 11,754 traded; Feb 19 950 call 134 with 11,754 traded. A strike that held about the traded size was being closed; one that held almost none was being opened.

Our read is a likely new bullish call debit spread. The lower-strike calls appear to have been bought while the higher-strike calls were sold, reducing the upfront cost and capping the upside. The position needs a substantial rally to break even at expiration; it can appreciate before then without the stock reaching that expiration breakeven. The entire debit can be lost if the stock finishes at or below the lower strike. The upper strike is the profit cap, rather than proof of a price target. Opening status and initiator direction are inferred; the payoff and exposure assume a new position in this direction.

The evidence. The call legs have matching timestamps, fill sizes, displayed venue labels and spread flags. The lower-strike fills were at or near the offer, and the paired net debits were toward the offer side of the implied package quote, supporting a buyer-initiated read. The later chain snapshot shows volume at both strikes far above prior open interest, supporting substantial new activity without confirming this specific position opened. Each displayed row is retained as a separate fill, including repeated sizes. The chain snapshot is used for prior open interest and session volume; execution quotes come from the earlier tape. The screenshot clock is interpreted as Pacific time and converted to Eastern for the log. The order filled 17% of the way from the price at which the read's initiator crosses the whole quote (−$15.52M) to the price at which they are paid it (−$14.34M): below the midpoint, which supports the read.

The other read. The package could buy back an existing bearish call spread, or form part of a larger position or hedge whose other trades are not visible. Prior open interest was far below the displayed size, which makes a pure closing trade against positions held before the session less likely. Intraday opening and closing activity can still produce volume well above prior open interest, and the tape cannot establish the initiating account or its purpose.
