In my previous SPX analysis, I was hoping to see it comes all the way back to 2641, but the 21 ema is doing a good job as a support here. If S&P goes up and close above the blue line region, then it will probably stop only at 3136, a sign of real strength here.
I was working with a scenario where the decisive point would be the orange line, but the 21 ema already...
