During the day, when it's a slow-moving day, I do research; I re-examine my trades to see if there is anything that I can do to improve for the future; I formulate new strategies to make my next profit bigger. There is ALWAYS something to do. A trader's job is NEVER done as long as he/she is alive and doesn't have Alzheimer's. And it's better to do them while the market is still open. And during that time, I would rather prefer to be alone and not chit chatting which I find could be distracting. And I like it that Elitetrader is NOT in real time so I don't have a scrolling screen that will constantly want me to go see what's the newest response there.
The only time that I would feel like chatting is now; the market is closed. It's the weekend, time for relaxation and etc. And even for the weekend, I still do research. There is ALWAYS something to read.
