comsec t+3, page-8

I had a $54 fee once and called up to discuss it and they were happy to reimburse it as a one off. I then read the terms an conditions.

When u buy shares money is needed first thing in the morning as they need to pay the money to the seller. When u are the seller u receive the money on the 4th morning not because commsec doesn't pay it on the third day but because your bank account clears it overnight.

Also this offsetting of buys and sells is the default on the account but can be turned off by a signed eritten request. It is the default on the account and can be easily turned off.

A few years ago I would buy one day and sell the next effectively never actually paying any money.
