Technically Speaking, page-641

I just read that back and it was very poorly written. I decided to add up the order detail on the sell side when I noticed commsec said 82k units total. When added manually I came up with 79500 units. On the buy side commsec showed 67k units total and I came up with 69k. So it is, or atleast was showimg the spread is wider than it actually is. Maybe no big deal but unless there are orders we cant see? I think its misleading
