I do agree with you but I also believe that there are some systems out there that can actually make a difference and help you in becoming a better Forex trader or at least helping you gain more profits.
One of these softwares are Forex Phantom, I know the people who are developing the product and I ve been lucky enough to test it and well even though its not released yet it did an excellent job at predicting the forex market for the couple of days I used it.
