just tried to find a description via a search put couldnt come up with one, even on the ASX site, probably why a lot dont know the term U ( undisclosed)order means.
Here goes: its an order put into the market depth by a certified broker which has to be $200,000 worth of shares or larger to qualify. It appears in the market depth as a U or OU and you cant actually see being just a retail trader/investor how many shares there actually bidding or selling.
I hope that made sense.
Cheers
