Special Trading Session (STS) Cross

A closing price cross resulting from an order placed by a Participant on behalf of a client for execution in the Special Trading Session at the last sale price. If the last sale price is at an invalid tick, a rounded equivalent of the last sale price (Rounded LSP) may be used to enter orders. 

Using the Specialty Cross Types

Although the specialty cross types may be executed anonymously, brokers must report each cross using the appropriate marker (i.e. basis cross marker, VWAP cross marker, etc). This alerts the ÍÃ×ÓÏÈÉú system that the cross can fall outside of normal market parameters. Each trade appears on all real-time TSX trade data. (In addition TMX Datalinx offers reports detailing the Specialty Price Crosses executed on a daily or monthly basis.)
