I know that in pit trading, there are floor traders. I might be wrong but floor traders are usually those who have and execute retail orders of you and me. 
My question is, are there floor traders on these two exchanges: NASDAQ and NYSE? Or some sort of "electronic floor traders" (which may be algorithms?).
