I follow these traders on Twitter for the following reasons:
@LDrogen: Leigh gives great trading advice (via stockTwits TV, Blog, etc). He likes hockey a lot, unfortunately not the right team ;-). Go Habs Go!
@paulwoll: This trader knows his stuff and he is generous with his ideas. Listen to how he hedges his positions.
@TVN_Kevin: I like his Fades and Fills reports. I highly recommend reading them!
