Unusual Options Activity, Explained

Unusual options activity flags strikes where today’s volume is large relative to existing open interest — the contract book got suddenly busy.

If a quiet restaurant suddenly takes a rush of reservations for one table size, something changed that evening. You still do not know whether diners will show up happy — only that attention spiked.

We look for volume/open-interest multiples above a published threshold (higher when a name is already tagged hot). Short-dated, farther out-of-the-money contracts are more often labeled speculative in tone; others may read as hedging-style.

When an earnings date is near, the panel notes “earnings D-N” so you can place the activity in calendar context.

Public prints do not prove whether the aggressive side was the buyer or the seller. Sweeps, multi-leg structures, and closing trades can look “unusual” for many reasons.

Treat the panel as an attention map, not a trade ticket.
