SQ9
This is a Gann tool that in my opinion is over rated, nevertheless a lot of people follow it so it is important to observe how it comes out when you identify a strong high or low using my more conventional methods.
Sometimes like in this example of the 1163 high it couldn't have been better as it was another psychological sign that fitted in with a bunch of other things.
Point is the market declined and didn't go higher so we have to give it some respect.
