From what I've gathered they are nothing more than nonsense.. I cant tell you the number of people I know that have their own "Signature" trade blocks..
Common ones are the 187, 911, 500, and so on... Those trades are nothing more than traders fooling around, and even painting the tape, which I'm guilty of.. 500 is my signature mark..
