To trade money with your accounts either drop trade (I have heard from several sources that drop trading isn't tracked unless somebody reports you), or you can use 2 different browsers, 2 different qualities, and 2 different java version (1 signed, and 1 unsigned), and then login with both accounts at once. then you can trade regularly. I don't think they can track that, I think they detect it as 2 computers on the same network using runescape at the same time, which is not against the rules.
