like in astrology where a planet is said to have an Orb of Influence of a few degrees on either side of the top dead center of the alignment so to do these major demarcation points on the chart, such as the mighty 9.
Its plain to see the Orb of Influence about the mighty nine goes down to 82.5. 82.5 being the halfway point between 90 and 75 or 9 and 7.5.
Not that the difference between 9 and 8.25 is anything to sneeze at for trading purposes. That's 75 cents($3,750) to be made when price moves back to...
NINE BUCK BEANS!!
