the price is to go to the next nearest angle above it. Question of scale It is not always practical to give the 1x1 a value of 1 point of price for each day, as Gann observed in his course. If, for example, the Dow Jones Industrial Average is trading around 10,000 points, it can be more helpful to apply a scale in which a certain number of points (like 100 or 1,000) is used as the price unit. Critics note that Gann did not set down rules for such cases and that the positioning of the angles on a chart is therefore entirely arbitrary and not scientific. This may not necessarily invalidate the methods Gann used himself, as it is not known whether he intentionally left some parts undisclosed. See also Financial astrology W. D.
