What he is asking is, for example:
Suppose he bought 1000 shares on 1 October and more shares in the same company on 1 November.Then if he sold 500 shares on 5 November. Those 500 would be deducted from his first purchase, ie: from the 1 October lot.
He is asking can he have the 500 deducted from his 1 November purchase? Why! dont ask me!
My guess is that the proceedure is ASX practice and hence applies to every broker.
