Unusual options activity is a type of trade being bought on the ask or sold on the bid, with unusual volume and/or trade size. This means that these are new contracts being traded, expressing a fresh opinion on the stock.

Why is this interesting? Well given a large enough trade and it being bought on the ask or sold on the bid it shows extreme urgency on the trader's side.

For example, let's look at a trade of 5,000 calls which had a bid and ask spread of $3.00 by $3.70 respectively, and the order was executed on the ask at $3.70.

What does that tell us?

The trader bought 5,000 call contracts, dropping $1.8M on the trade. Now, if they were patient and waited to fill the order in the middle of the bid and ask spread, say $3.35, they could have saved potentially $175K, but they didn't. To me, that says they have high expectations for this trade, and saving $175K is chump change.

A large purchase of call options carries a signal that there is a likelihood of a large move in the underlying stock.
