Standing orders to be executed when funds become available. For example I put tech on sale and want to buy defense once it sells. If you only play once a day then that is a long time to wait before you can buy up defense, especially on express.

It also allows you to wait for the 18 hour bonus.

If this will be abused somehow than maybe its only for private markets. It would make destock smoother for people who can't be on the computer at the end of a set.
