I have developed an Exponential Moving Average called Jagged EMA which accommodates volatility and EMA together. Visit http://www.forexbrace.com/content/view/197/52/ for more information about this EMA and download your free copy.
Obviously this would be placed more appropriate in classifieds. A propriate moving average - hope nobody believes that this is the latest development in trading tools?
It's a free tool and not for sale. I have not run into something similar. I think it has its own characteristics but it would be great if I see somebody has done something similar in the past.
