Used you chart for trading today and also played with some variations. Actually the results were very good.
I put the RSX Range Extension into the subwindow of the RSI ma , replacing the MA.. The RSX Range Extension is actually a very good indicator.
The dotted line is a simple MA 144 for reference. Above that I trade only long and vice versa.
I also use Trendenvelopes which pretty much draw like Trendlines with this setting.
Just my 3 Cents as an alternative view. I understand that this wanders away from your original chart.

.......Period 3, MA Method 2
I use original setting
