Cant Trade On Website?

So I set up 2 step authentication and waited 3 days so i'd be able to trade on the website trading system,
But when I went to do it, it says I'm not eligible to trade What else would prevent me from trading ??
Any Help is much appreciated... Ive had the account since 2013 Molten wow days
