Take a look at the trading links on my profile. It opens a trade screen to my inventory. You would have to use a different url link to open to yours. Copy the url link from a trade forum button for a trade you've offered and copy it to your profile. This should help you get trade offers. Let me know if I can help

As far as I can see in settings, profile and inventory are open, deals can leave all users, regardless of friends or not. So I don't understand where and what link I should leave.

There's items for trade but no trading link on your profile
