I understand what you are saying, but you are misunderstanding the difference between bidding and buying. I didn't underbid most of FFA because I did in fact have the highest bid. When you go to the market and out right purchase a good, that is not bidding. Bidding requires the buyer to set a certain price level and the seller to accept that price. When you buy from the market that is not on a standing order, the seller is setting the price and the buyer accepts that price.
