Description
A Massive options ticker is four parts joined together: O: then the underlying, the expiry as YYMMDD, C or P, and the strike in thousandths padded to eight digits. So O:SPY260918C00650000 is a SPY call expiring 18 September 2026 at a strike of 650.

Description
From OPRA, the consolidated feed that every US options exchange reports to. That is 19 exchanges on one tape, so the coverage is the whole US options market rather than a selection of exchanges.

Description
Yes. Massive publishes every options print whatever time it happened. Most contracts stop with the equity market at 16:00 Eastern, while broad-based index and ETF options trade on to about 16:15, and their prints are on the trades feed like any other.
