Its about time someone brought up this subject...
Trading is a highly personal thing.
And having a room full of people talking about the weather or similar irrelevant stuff isn't helpful.
Even people entering such rooms and saying hello can be distracting. I think your find that most successful traders focus on the markets rather than whats going on in a chat room !
The trouble with chat rooms is that everyone is trading different things and different strategies.
The best chat rooms i have seen are ones where very little is said except by a few main traders. But they are US based and i mainly trade UK stocks. A good chat room should be mainly quiet except for detailed financial chat.
Whats needed is a few small chat rooms with only a few people in them trading the same stuff with similar ways of trading.
I'm interested in one and they can be easily set using AIM where if you know of another trader who trades the same way you can invite them into the room.
An example of a good room would be where everyone was trading CM's DOW strategy or NB's Forex Strategy
I could open one up for UK stocks if any full time traders are interested.
