I am using Elliot Wave as a secondary method while trading the ES.. I find it particularly useful as another indicator, another green light if u will, that lets me know that i'm probably going to be right on a certain trade.
However, I have found it very difficult to use it accurately in all situations. Perhaps that is just me, but I find that my eye is not quite as sharp in many instances or that i just can't tell what wave we are in.. The best trades for me are when my system gets a signal and the waves fit the classical pattern in a very obvious manner....But i haven't used it for very long, so perhaps over time I will get better at it and be able to discern some of the more subtle patterns..
