The end of the trading day was like the end of a battle. After five o'clock the Masters of the Universe took care of all the things people in other businesses spent the entire day doing. They figured out the "net net," which is to say, the actual profit and loss for the day's work. They reviewed the markets, reviewed strategies, discussed personnel problems, researched new issues, and did all the reading of the financial press that was forbidden during the daily battle. They told war stories and beat their breasts and yodeled, if they deserved it. The one thing you never did was simply go home to the wife'n'kiddies.
