I reckon your correct with those trendlines and the last move looked like the running stage before exhausion.
I tend to look now at H4 to see if it bounces over the red box area to see what happens next.
If it thrusts down again, I will sell
If it breaks box with perhaps a retest, I will be buying.
I won't take the Buy unless I'm convinced its moving up ( out of the Yellow area which is the H4 63EMA or Day 10EMA )
