I read this at another website, is this real? "Traders on the floor of the New York Stock Exchange wear an "X" on certain places on their clothing to mark areas where they have been injured so that other traders can avoid bumping them there. " Sounds BS to me but what do i know....
I can confirm this is true. It's is very crowded on the floor and people bump into each other alot. The X let's people know to be carefull.
