Trades should not be posted or organized on the site.

That's not how Trading card listings on Steam work. There are no indivual listings so everythings depends on the asking price and the order in which they have been put up for sale.
Basically all cards that have been listed for the same price as yours before you did, will be sold first. Even if somebody wanted to buy your cards first it's just not possible.
