So the primary reason you haven't had any trade offers is because you don't have any cards listed in your tradelist. Second to that, you aren't a member of any of the trading groups that would really yield your name on any search results. Third, you have your trade preferences set to local, indicating to people that you will only trade locally or otherwise in person. Fourth, you currently have a trade reputation of zero, indicating you have yet to complete a trade on the site with anyone.
Combine all four of these things and it would certainly explain why you aren't getting any trade offers.
My suggestions if you're looking to get started trading:
1) Set your trade preferences to "My Country" so that people will know you're wanting to trade via mail.
2) Join one of the trading groups on the site. Typically RedditMTG is the best one here as it has the most members. This will let you come up in other peoples' searches at the bottom of their front pages (and vice-versa).
3) Actually populate your tradelist and wishlist. People aren't just going to ask if you want to trade something from your inventory if they don't know what you're looking for or what you're willing to part with. Fill those in and then people will actually find you and can initiate trades.
4) Go find a few people with higher trade reps and complete a few trades with them. These can be small scale $4-5 trades. But they'll get you started and will get you a trade reputation such that people will actually trade with you. Just be aware that most people ask new traders to send their cards first.
- Be sure to note the trade stickies in the trading post and other forums regarding when to put shipping on cards, how to pack them best, etc.
Good luck and happy trading!
