Choose whether you want to sell or acquire resources, the type of resources you want and the quantity. For a sale, choose the initial bidding price, and the buyout price that allows another player to buy directly (ending the auction). For a request (where you are looking for a resource), choose the maximum cost you are willing to pay (at which the auction will start) and the minimum cost, at which another player is able to sell to you directly (ending the auction). You can also choose a delay for the offer or request.
