This is a follow-up of my previous SPY chart. S&P 500 Index. I have kept the previous time periods the same, but made the shorter 23h periods to be less bold, smaller lines, and I added an APPROX 3d periods which are dotted lines and somewhat bold green and red lines. These may need to be recalibrated after every weekend, possibly. I believe this may give us a better picture of several zones at the same time. This is a private idea.
