Term	Definition
Exception Type	"ATS Cross" detects potential market manipulation where a market participant engages in a potential manipulation of the National Best Bid or Offer (NBBO), resulting in the modification of the security’s prevailing mid-point price on an ATS crossing venue. This activity provides an economic advantage to one side of an imminent cross transaction occurring at the modified mid-point price, where that advantage would not have been achieved absent the modification to the NBBO. "ATS Cross – relationship" involves two separate market participants, with one participant modifying the NBBO mid-point price and the other participant receiving the beneficial execution. "ATS Cross – non-relationship" involves the same market participant modifying the NBBO mid-point price and receiving the beneficial execution

Activity Description	The activity description provides a frame of reference for the activity captured in the exception.
