What is unusual options activity and how should I read it?
Unusual options activity is trading in a contract that is large compared with its normal volume or open interest, for example volume above open interest or a single print worth hundreds of thousands of dollars. It shows where money went today, not why, and much of it is hedging or closing trades.
What counts as unusual
Common filters: premium above $50K or $100K, volume greater than open interest (suggesting new positions), short-dated contracts, and orders that sweep several exchanges.
Reading it without overreading it
One large print can be a hedge against a stock position, a spread leg or a fund rolling an old position. Repeated buying at the ask in the same strike and expiry, with open interest rising the next day, is a stronger sign of a new directional bet than any single trade.
Where to see it
GammaPulse's Flow page records every print of $50K premium or more, labels bought or sold, flags spreads and repeats, and keeps past sessions so you can check what happened next.
