Which brings up the question of why one would need to solidify their status of being a "Trader" by wearing a t-shirt? Who cares about what others think.

BATS ecn needs a shirt "Master-BATSer" EDGEX could have femine undergarments with "Post Your liquidity here"
This shirt will have all your friends thinking: "Jesus. How'd a nit-wit like you get so tasteful." (If you're wondering about the shirt, that's pale nimbus white and the lettering is something called Silian Rail.) hehehe
