Unusual Options Activity Scanner and Alerts

What makes options activity “unusual”?

Unusual options activity is any trade that breaks sharply from a contract’s normal pattern. In practice, four signals do most of the work: premium far above what the name typically prints; volume that exceeds the contract’s open interest, meaning new positions are being opened rather than old ones changing hands; aggressive sweeps that pay up across multiple exchanges for immediate fills; and sudden activity in strikes or expirations that have been dormant. Any one of these is worth a glance. Several together on the same contract is what traders mean when they say the tape is “talking.”

New to the idea, or want to run the tests by hand first? The guide what unusual options activity is and how to spot it walks through all four with real prints and the false positives to watch for. This page is about letting the scanner do it.

The reason unusual activity gets attention is simple: someone chose to commit serious capital, quickly, in a specific strike and date. That does not guarantee they are right, but informed positioning ahead of news, earnings, and analyst moves tends to look exactly like this.

Signals, scored and surfaced

Robinflow’s Signals feed does the pattern-hunting continuously and labels every qualifying trade with the reason it stood out. Repeated fills flag the same contract being bought in many pieces within one order. Exceeds OI marks repeated buying that adds up to more than the contract’s open interest, a sign that new positions are being opened rather than old ones changing hands. Large trade and Size exceeds OI flag single orders as big as, or several times bigger than, everything already open in that contract. The newest qualifying trades sit at the top with their labels, so you can see at a glance why each one made the list.

From signal to alert

You don’t have to watch the feed all day. Put your symbols on a watchlist and Robinflow pings you when they print notable activity, with a daily Highlights email showing what changed on each of your names. The AI smart filter works here too: describe the kind of unusual activity you care about in plain English and monitor exactly that.

What unusual activity can and can’t tell you

Unusual options activity is evidence of intent, not a forecast. Trades can be hedges, parts of spreads, or simply wrong. The honest use of a UOA scanner is narrowing: out of thousands of symbols, it tells you which handful printed something abnormal today and lets you investigate why. Robinflow pairs each signal with the surrounding options flow, news, and analyst context so that investigation takes minutes instead of hours.
