I encourage you to check out the Othernet server. There are many rooms for traders. Sadly, most are 95% lurkers, and many are . . . more concerned with issues other than trading. But there are a few good ones. Network with people on the servers who seem to know WTF is going on to find other rooms.
And, if (while in a good sized room) you voice some good opinions or otherwise demonstrate value, you just might get invited to one of the private ones. The best rooms on Othernet are not public.
