Hi, I am reading and experimenting the strategy reported in the Ehlerìs mentioned book.

I Found some indicators and tools already available in Zorro even with different name.

is the Cyber Cycle Oscillator already present in Zorro?
In the EL code is called High Pass Filter but I do not think is the same Zorro's one. On top of that we have 3 HPF.

Which is the correct one?

Thank you in advance
