WPO - Wave Period Oscillator - Indicators

WPO – Wave Period Oscillator

A Time Cycle Oscillator – Published on IFTA Journal 2018 by Akram El Sherbini (pages 68-77)

Bullish signals are generated when WPO crosses over 0
Bearish signals are generated when WPO crosses under 0

OverBought level is 2
OverSold level is -2
ExtremeOB level is 2.7
ExtremeOS level is -2.7

As with most oscillators, divergences can be taken advantage of.

bellissimo lavoro, Roberto, grazie!

I just discovered that ProOrder (for automated strategies) does not evaluate the expression in line 15 correctly (as Probuilder does), so if you want to embed the code in your strategy you need to replace that line with:
//Ti = ((close > Cy) * Tt) OR (((close Cy) THEN
Ti = Tt
ELSE
Ti = -Tt

  Hi Roberto
  the WPZO is the bounded oscillator by percentage like the SHO
