DXY vs SPX - longer period

Just as an extension to pure #DXY (see linked idea) I've added SPX price chart.

I have shown previous recessions and market depressions for past 50 years and behaviour of #DXY & #SPX.
Blue bars patter copies DXY rally after 1980 recession, which is of course just hypothetical.

Hypothesis:
- #long on #DXY
- #short on #SPX
