On the right side chart using Simple Moving Averages (SMAs) you can see that the 20 moving up through the 50 caused a very predictable spike and not only that but the 200 also provided a reasonably accurate target point to exit. In addition, as you can see form these two charts, the chart side shows much better support resistance correlation on all of the averages with the price point.
Conclusion... So I'm not seeing any advantage to using DEMAs at this point over SMAs but perhaps on a different time scale chart there may be better results so I will research this a little longer.
