How Unusual Options Activity Alerts Work
Unusual options activity occurs when options volume on a stock is significantly above its average — particularly when large block trades arrive in a single expiration or strike. These flows often precede earnings reactions, M&A announcements, or other catalysts that institutional traders may have anticipated through deep fundamental research.
Not all unusual options activity is predictive, but consistent patterns — large call buying at out-of-the-money strikes weeks before earnings, or sudden put sweeps across multiple strikes — have historically been associated with informed positioning.
Stock Alarm Pro tracks options volume across the major expiration dates and fires alerts when volume exceeds 3× the average for a stock, or when single-block trades exceed threshold sizes. Combine with fundamental analysis and upcoming catalyst dates to assess whether the options flow aligns with a specific thesis.

Frequently Asked Questions
- What volume multiple counts as "unusual" for options?
- General threshold: options volume 3× or more above the 20-day average is considered unusual. Volume 5×+ is highly unusual. The relevance also depends on the strike and expiration — near-dated, near-the-money calls/puts in large size are the most significant.
- Does unusual options activity guarantee a move?
- No. Options data can also represent hedges, covered call writers, or systematic strategies rather than directional bets. Context matters: unusual activity ahead of a known catalyst (earnings, FDA decision) is more significant than activity in a quiet period.
- Can I use options flow for short selling ideas?
- Yes. Large unusual put buying — especially when it's well above the money and in near-dated expirations — can signal institutional hedging or directional short positioning. Look for put sweeps across multiple strikes as the strongest signal.
- How does Stock Alarm Pro source options data?
- Stock Alarm Pro uses real-time options market data feeds to track volume by strike and expiration. Unusual activity is identified by comparing current session volume to the rolling 20-day average by expiration.
