They are not worthless. Its all about understanding how they come about and using them correctly. Don't let people tell you they are worthless or they lag price etc. You are not going on a competition of who wins more. You just want to beat the market every once in a while. They may lag but its a confirmation that you are after, right? Furthermore, its not about the indicators. Its all about YOU! as a trader. If you are impatient, greedy, indecisive and doesn't have a plan, its will be all useless even if you are a master of all the indicators in the world.
