If you need to have a group full of forex members where you can have a live chat then you need to join faceboook and create a group. There are a lot of people that are searching for such groups. You can then share the link here for anyone to join. It wil be much easier than having everyones skype id. Most peole will not provide you with that information.
It would be much better if the group did that. If the trading idea is shared by all, then the trading speed increases even more. Trading requires a lot of experience and the experience of each person is different and if you combine these experiences in one place, you will get much better results in Forex trading. There are many Forex groups online so if we want we can open a new group that everyone will be able to join.
Sharing trade ideas can be very destructive. You can form a group for study purpose but for trading not a good idea. Every person is psychologically different. And trading is more of a psychological. By seeing others trade ideas will hamper your own judgement. It will make you confused.
