i guess maybe it depends if u bought or sold first??
thus leading to insuff $$$..
Just call commsec and tell them in future, to net of ALL trades...
and then all u need to do is theres sufficent funds on the net difference on the T3 date.
Call em, they should xplain it to ya.
I have a direct 02 sydney number to call... but Hmm I dont wanan risk it on this site
