Laguerre PPO Oscillator for Amibroker

Laguerre PPO Oscillator is just the translated Tradingview Pinescript indicator from theLark’s Laguerre PPO. We very well know that Lauggerre RSI is from the John Ehlers library and Price Percentage Oscillator (PPO) is a classical momentum oscillator. So Laguerre PPO is nothing but a fusion between Laugerre RSI and PPO Oscillator.
