I've been trading in my T6 for about 2 weeks now, with a little bit of bounty hunting in my Cobra for a change of pace. One thing that I've recently found that is kind of fun to do with trading is just go from port to port and sell the best thing from there to the next. Since the fix for the commodities has been tweaked a bit on the "crazy" side right now, I'm finding it fun just to find the best commodity to sell from where I'm currently at to the next closest buyer. And let the next take me wherever it may, sometimes into friendly territory, sometimes into anarchy space, sometimes selling something as simple as tea and other times big tech, minerals, or slaves. Its kind of fun to just see how far I go for awhile, and even if its not always top credits, its one of those things where I'm just having fun trading along the way.
If you want to give it a shot, see how far from your current hang out you end up at after a couple of hours. I use Thrudd's Online tool
http://www.elitetradingtool.co.uk/ and while some of the info may be outdated, I take the time to update it and just type in my currently location and see what trades for the best credits from there say within 25 lys, 500 ls or closer, and at least 600 creds or more profit. Then I keep going to the next one, in whatever direction makes me the most money. And as of yet, I have not had it take be back and forth, its always been a new place that was better - so that is cool!
