"Asking price" is the current highest priced standing order for that good. If there is no standing order, then asking price is listed with a dash (-).
From the ingame tutorial:
"Standing orders allow our country to conveniently purchase goods even when we aren't logged in. If we put up an order for Q quantity at price $P of good G, then our country will buy purchase up to Q units of G for all prices less than or equal to $P."
Offtopic: I bet a lot of people don't read the in game tutorial texts. Such as this one:
"Account for random chance!
All attacks have some element of chance. Our generals calculate that if we send more than 110% of the defender's power our attacks will be successful more than 99% of the time."
