You're right, mazooka. It didn't occur to me that cheating could be prevented my doing this because I overlooked the fact that standing orders went into effect almost instantly. I thought there would be a few hours wait until the order went into effect.

I was wrong, this is a good change.

EDIT - Wait if afaik is correct then standing orders can still be used to cheat. If afaik and I are cheating and he wants me to transfer some cheap turrets to him then he can place a standing order for 100K turrets for $70 and I can sell them for the same price.

If afaik is correct then as long as no one else had a standing order of $70 for turrets, then there's no stopping him from obtaining my cheap goods. I like the idea of a standing order for a higher amount trumping the standing order for a lower amount. This WOULD stop cheating.
