DislikedI agree with you, its difficult to built an edge in forex trading, since its different from one to another participantsIgnored
If you don't have an edge then ultimately you may as well flip a coin. (money management and discapline are irrelevant without finding an edge first).
However an edge is very, very difficult to find. Why? Because over the long run almost every variable/parameter gives a 50% percent probability of success.
So whatever you choose: breakouts, inside bars, MA's, in the long run they give a 50% chance of success. This is not an edge.
Another major flaw with Forex trading is that as soon as a significant edge has been discovered. Widespread computerised trading will erase the advantage. IE the edge will disappear.
