ya Any business or any profession if you enter without enough knowledge and experience it is going to difficult to survive in and so is in forex, trading without good preparation and knowledge may be very dangerous as there is big risk involved and trading in forex is walking from the jungle of thorns where little carelessness may result into big losses. in my view its answer is that...you should learn the proper course before start real trading because if you will start it without proper training so it will kill all your capital and your all trades would go in loss because you are doing it without getting proper knowledge
