Hmmm....fellow PO3 holders may find this interesting....

I'm a bit OCD and had a little change left over so decided to put in a small order today for a few units to round up the number of units I hold - only to have the order cancelled - with the stated reason "Orderly Market - please call Commonwealth Securities"

New to this game - so no understanding as to why - but I assume it's to put a stop to / limit the impact of the market shenanigans resulting from bot activity.
