I'm not much into stocks but does the squiggly trendline snakey guy have a name?

Y'know you jest, but when I was very young I didn't understand why all the other kids I could just call by their first name, but the girl across the street I had to call "Miss Shell"

It stands for Mark

The name is Mr. T. First name is Mr, middle name is that period, last name is T.

— Mr. T
