How Does The Trade Market Work?

I'm looking to sell an item there, but am not sure exactly how it works/if there is a format for selling there.

 

To be honest nobody really cares about what you post in the trade market (as long as you're actually buying/selling something)

You can just say in the title "Buying Taurus" and "look at title, paying 5 LE"

 

You ask if anyone has that item that you are looking for and someone that has it will tell you the price and if you agree you can meet up and trade that item.

 

Thanks!
