Looks like you have the 100 day regression channel there...
On AskResearch, if you slice it different ways, today's candle still hits the upper rail. Dunno what the explanation is for the difference.
I pulled the plug, I am out of the Dow long now. But I did not go short either, just flipped it to a long position in SPX. That one is not so overbought, but it is starting to get close. Maybe I can squeeze a few percent out of it before it pulls back.
