By entering the price of any major low, the Sq9 will show you which numbers fall on the significant angles. The yellow are the more significant because they are divisions of 90 degrees. The light blue are significant as price progresses further out. If you enter a major high price into the starting price block and put a minus - sign before the step number, you will get all prices that are significant on the way down as price will grow less as it progresses out ward.
