Trading is a lonely profession. Here are some excellent social groups that you can join to chat and find other traders.
www.trade2win.com: It gives possibilty to seek out other traders in your area.
www.advfn.com: Offers some services to traders. Includes GTIS quotes.
Any social group platform is also a good source to find traders:
Note: there are open groups and there are limited ones. The ones that are open are often full of junk and no specific strategies are discussed there.
TODO: Add all the social groups I use in the future.
www.csta.org - Canadian Society of Technica Analysts.
