Many traders think they have found the "edge" ie they have found an entry/exit criteria or speed of service etc that the rest of the market doesn't have. Nothing could be further from the truth. Any edge these folks think they have is already being seen and used by many many other traders. --However what most traders don't have is the ability to prudently manage risk and those that do , have the edge in this business. The inability to manage risk is what causes downfalls or if profitable, reduced gains. ---
