The only difference is that before the broker didn't know I expected to place any orders, and treated them as instant orders. But, for all intents or purposes they are pending orders, because I know where they are going to be placed, that is, in accord with the last closing and initial opening prices, etc.
Oh, and if you'll notice, that when one pending order hits its target (opens a Buy or Sell), the other one is deleted.
