I'll agree with you, for the longest time there was heavy resistance at that Dow 18000. Hard to tell what will happen next time if it ever gets back there. Support is harder to read because everybody has their own idea what a "dip" is.
that's why they call it a "health restoring correction" because it shakes the usual players who were creating resistance out. So next time we have enough energy fueled by new buyers and the old holders to break through the resistance. I know you didn't want to talk about TA, but you started it when you mentioned support. But I get your idea, you wonder why support at 1940 didn't hold when China acted. Carry on
$SPX Do my eyes deceive me? China is green? Only took $24Billion injection, interest rates, pensions, etc.
$SPY Yesterday, couldn't hold 193, but you do today, we'll squeeeeze (much) higher, America. China acted. America healthy. ...Will you act?
