Character trade with friend without marketplace?

Hey guys,

is it possible to trade two characters (between a friend and myself) without the marketplace?
Of course we need to pay coins for service fee, but we don´t wanna pay 300+ coins to each other or tryin for less coins and see them catched before trade...

Greetings

Sorry but no, policy states that any outside market trading is bannable, so sadly have to do it this way.
