Hi I am new in this forum. I have been through zorro tutorial and I was very impressed by it so I decided to spend more time on it to understand more deeply how it worked. Naturally, I start reading the book "Cybernetic Analysis of Stocks and Futures" and the algorithm for the Low Pass function. I have to be honest, even if I have some background in math I haven't understand the algorithm explanation (which requires some electronic/physic background).
Still, I implemented it in mql4 in order to compare it with the exponential moving average. If you compare the LowPass(100) with the EMA(50) you get exactly the same peak and valley with no lagging. The point then, is I don't really see the added value of the LowPass filter. I wonder if I missed something??? (in the image the LowPass(100) is in red and the EMA(50) in green).
