Wayne , Gann used certain geometric squares and custom squares . This is where the balancing of time and price comes into the equation . Gann would look for time and price to come into balance and when these two componets were in harmony we could look for a possible change in trend . Squares were an important part of his analysis and he used several squares for several markets . Looking at the square of 144 , it is a complicated process and you need to ensure that your chart scales ( time and price ) are balanced otherwise the true geometric balance will be skewed . try setting up a 1x 1 angle on the DJIA as I discussed in previous post and you can begin to understand the difficulties , I mainly stick with Commodities and some Indexes as they lend themselves to this particular line of operation . Everything is interconnected when it comes to seasonal time , 360 deg is equivalent to 1440 as there are 1440 mins in a day , 180 deg is equivalent to 720 as there are 720mins in half a day ( See Circle 24 post ) so the square of 144 like other squares needs to be set against the chart . if you assigned an arbritary no like 4c per day you would complete the square in 144 days and be up 576 pts which is not balanced , if you went up 72 pts in time in 72 days you would be 1/2 square in time and 1/2 square in price , if you went up 144 pts in 72 days you would be against the 2 x1 , just because 144 has expired doesnt always constitute a trend change , price could be up 96 pts in 48 days against the 90 deg angle , there are alot of subtle geometric applications just within this square so balancing your co ordinates and setting up your chart properly is very important , hope that helps
