Is SPX In an ascending wedge on the weekly?

I think so. The solid red trend line correlates with the solid red measured move.

The dotted red trend line correlates with the dotted red measured move.

If the ascending wedge breaks then look for support from the green trend channel line. If the green trend line does not hold up then look out below and look for the measured moves to play out. Most likely an multiple enormous wicks to the downside over the course of 2 to 3 weeks and the price SHOULD hop back into the green trend channel.
