In addition to these specific criteria, SpotGamma also provides four flags which characterize the executed trades:  

Sweep: Large option order that has been segmented into multiple smaller orders across different exchanges; the Sweep flag indicates that this specific trade is part of a larger trade.

Cross: Indicates when the buy and sell orders match exactly for a specific trade, meaning they cancel each other out.

Block: Privately negotiated options trade, typically large and executed outside of public markets.

Multileg: This flag indicates that the trade is part of a larger options strategy involving two or more options at once.
