BLKB

That span is 136days, so it covers the report plus the ordinary movement around it. The chain doesn't yet quote a second expiry we can separate the two with; the range narrows onto the report as it approaches.

If BLKB moves ±21.3% over this report, these carry part of it. Fund rows are arithmetic on published holding weights — what an index fund does by construction. Company rows are ranked by disclosed tie strength.

Contracts already committed, not just traded today — puts against calls, sized by expiry. The tick is today's volume moving against that stance; the arrow, how much built up since the prior session.

The stamp starts filling with the next report we price. It pairs the move the options market expected with the move the stock actually made, so the multiple between them accumulates into this company's own record. Nothing is back-filled from figures we didn't observe.
