The Art Of Daytrading

Both my father and my brother are involved in daytrading. I know that they are very good when it comes to selling and buying stocks. They were really happy when they found out that daytrading is already possible for casual traders like them. They both said that they prefer buying and selling their stock in the same trading day. They told me that there are things that one must know for him or her to be a good trader. I would also love to be like them in the near future, but I know that I still have so much to learn.
