Many thanks for everyones comments re where to find 'Depth'. The help on this forum has been brilliant & v much appreciated. I've been using ANZ Securities website for last 3.5 years & slowly built up a reasonably substantial portfolio of 9 shares (including OCA 7%, SUM 10%
of portfolio) & hadn't realised that tool was available on the ANZ site. Will def use it, with discretion, in future. Agree that a few cents here & there are unimportant as long as they're excellent companies in their field, & there's strongly growing demand in the field their operating in, both of which would seem to apply to OCA. Still just a little wary of just how big a 'cloud on the horizon' the overhang turns out to be or not to be!
