The concept of measuring time and space is very important for the study of
time cycles. PI is used to square the circle, it can be used to square both time
and space in time cycles analysis. PI can be used to find turning points in the
stock market because it can forecast when a cyclical move will balance itself
in time and space (where space is price). We will draw trend lines from highs
and lows of its time series with slope (number of points per day) equal to PI or
to a fraction of PI. Such trend lines will connect lower lows and higher highs in
the chart.
