Your question is answered in the reminder near the top of the page. Both active and pending trades count against your trade slots. You have 4 active and 3 pending trades, that's 7 in total, you have 5 trade slots, so you will have to delete two active trades. At that moment, you have a total of 5 pending+active trades and also 5 trade slots. You can then start accepting the trade invitations form the pending trades. PS: I hope you do so fast, as I am on 19 days.
