For me, keeping a long GDX and a short IWM is sound, because it hedges against any sudden market melt down or melt up.
I made a discretionary exit at the bottom (looking at the RT MF drop), and GDX took off without me. Re-entry made sense upon reversal, but I waited for the robot to show statistical edge for re-entry - which it did not. A hedge still seems sound, but after today's jump it feels 'too late'... Mixing a mechanical system with discretionary decisions rarely worked for me; regardless of the outcome of the initial deviation from the system, it is difficult to figure out what is the right follow-up discretionary decision in order to 'get back in sync'.
