In nature, many things are modelled after the sine wave. EX: Night and Day, Hot and Cold, Light and Dark, Loud and Quite, Up and Down ect. The idea is that the smart money algorithm is also using a sine wave model to determine price action. By incorporating the sine function into USD JPY market data we can use Ehlers Sine Wave Indicator to anticipate where price will move to, instead of waiting for it to get there.
My support/resistance levels were created by using signals from Ehler's indicator with a L50 SWMA.
