In my opinion, trading can be done individually as well as with a group. If you are familiar with the trading know-how, you can go as an individual. But if you think you need suggestions and ideas for trading or want to share your experience, trading with a group is a considerable option. Trading in a group results in lots of ideas and new trading techniques. For a newbie, trading in a group is a profitable option. It is all upto a trader whether he/she wants to trade as a loner or wants to trade within a group.
