Hi Conrad
From an AIMing standpoint it doesn't make a bet of difference.
In the US it can make a BIG difference in when you have to pay taxes for a gain. If you can sell share you have a loss on then you pay no taxes that year and delay paying them if at all into the future. Also in the US there is a difference in LONG TERM gains and SHORT TERM gains with the dividing line being one year.
