Interesting you should be talking about XT's and what they mean. I understood an XT to be something like Nightstalker explained, or a prearranged trade, but today I bought a parcel of WMT and the whole sum went through as an XT trade!

I had been sitting on a 6.5c bid for a couple of days, decided it may not get this low and changed to 7c during the afternoon. I am with Comsec. What do you all make of that I wonder?
