This implements the Even Better Sinewave indicator as described in the book Cycle Analysis for Traders by John F. Ehlers . In the example I used 36 as the cycle to be analyzed and a second cycle with a shorter period, 9, the larger period tells where the dominant cycle is heading, and the faster cycle signals entry/exit points and reversals.
