When I first started I was using minimum of 50 running weeks, max 50% drawdown, max drawdown pips to 400, best trade > worst trade and that usually comes up with quite a few. I like to make "sections" which I don't know if you can group traders in differing folders to keep track but in my mind I've been making sections for these traders based on how I feel they are with risk. I also just scan randoms and see what they might be thinking, as well as the top traders which obviously may be risky due to the fact they want to let it ride so they get a higher percentage winning.
I find zulutrade a very useful tool so that you can learn from these people. I assume finding good quality traders is almost as hard as finding good quality trades. I'm the type of person who likes to learn what not to do before I do something, for example when I work on my vehicles I go to the forums for the vehicle and I look up "jobs gone wrong" so I know when I want to pull this clutch out of this car I know what not to do first.
Some of the traders I have on follow currently are T.C.Y., Newwave, New Lexus (lol), fenix7, calipsofx, and AZ eurusd.
