UOA highlights unusual observed options activity using grouped orders, detected multi-leg structures, historical comparisons and market context.

The selected print is a reference to the activity behind an alert. The engine also considers size, execution patterns, volume, open interest, volatility and the quality of the available evidence.

Unusualness is not a probability of profit. The flow direction is inferred, and the displayed option-price returns do not reveal a trader's complete position or P&L.
