About this data: Options flow and unusual options activity
US options trades as they print, the trades that stand out against a contract's normal volume, and where dealers' hedging is likely to add to or damp price moves.
What is options flow?
The stream of options trades as they print on the exchanges, with the premium paid, strike, expiry, size and whether each trade was bought at the ask or sold at the bid.
What is unusual options activity?
Trades or volume in a contract well above its normal level, or above its open interest: new positions large enough to stand out from the day's flow.
What is gamma exposure?
An estimate of how much stock options dealers would have to buy or sell to stay hedged as the price moves. Where it is positive their hedging tends to damp moves; where it is negative it tends to add to them.
