The unusual options API alerts users of market activity typically representative of a large institutional trader or hedge fund taking a position. This activity often precedes a move in the underlying stock and thus is an important source of information, even for non-options traders.

Unusual options activity is a valuable tool in tandem with Insider Trades – retail investors like to know what the “smart money” is up to.
