It all depends on the person and his ability according to me but, if you are a serious trader than 3-6 months before you are going to practice on a live demo, at least you read a book or website that apart from the experience and education should be planned with the addition scroll in the forum, as you have already experienced people who can not read reviews. Over time, the rest of the experience increases, the more time you spend and the more you know it, it will encounter.
