XT on its own is just a crossing. Does not necessarily mean it was an actively brokered crossing. It is simply that the buyer and seller are in an on-screen trade just happen to be using the same broker. Ie Comsec.
Which I use as well and have seen some of my trades go through as XT.
XTSXOS: XT - crossing, SX - portfolio special crossing, OS -overseas. What you can read from this is its usually a larger parcel being moved from one place to another and is an off screen off market transaction. Could be an institution or large holder moving stocks from one holding portfolio to another or it could be a brokered transaction between two parties.
hope this helps.
