You need to make your room a Trading/Shopping room. I think there's some other TYPE of room you can use, but I definitely know that it's Trading/Shopping rooms

After your done trading you can leave by going to the southern portion of the room.

Change the room type from what it is to trade. It's in room settings.

In order for you to get a trading pass, your account must be 3 days old. Once you pass that, go into your room. Click on settings, change the room floor to "trade".

Clubhouse, trading room
