Hi Krelian99,
I was just revisiting your response to my post quoted above where you said:
From you responses you seem to really know a lot about cycles, filtering, etc, so could you please let me know what other types of filters do you recommend for proper filter design?
Thank you very much.
Regards,

I actually missed it till now to do it properly. I had so many other interesting stuff. I followed the filter nothing approach, since for proper filter design you need a program like Matlab and I hadn't the time till now to charting Matlab with the MT4 data feed. Financial data also follow other rules than technical data. There are natural rules, so clear boundaries are given like damage in material the available amount of energy. Here are no natural rules. Here, a fat finger of a big player and the price jumps 50pips up or high, we also had 150pips. The boundaries in financial markets are S/R, singularities though and a proof that markets are human driven and the algos also behave like humans.
When you want to filter NTL, you need to know what to filter out regarding to your concept. Disturbances or the shakings or high till low frequency. Scalping don't need the higher frequencies, while trend following needs no lower frequencies. It must be clear that Online-Filtering also always has a delay, otherwise it's intended repainting (for offline use). You must do a system identification. Bode-Diagram is normally a good tool, but I doubt it helps in financial markets. They are too dynamic. In FX is a calm Asian Session, here it could help maybe. Of course there are much more powerful SI-tools, but I never checked them for FX. Neural network machine learning maybe could also be interesting, but here I know too less.
An often used simple FIR is the EMA or SMA. As dynamic S/R it is pretty good. Cause and effect are changed here, so IMO people who say an EMA is mathematical manipulation of price are not wrong but they use it the normal way. Here, the price tests the EMA whether bulls or bears come in or stay out (I have tons of examples), so some candles on the chart follow the EMA. This is a failure in the causality (seeing the future, e.g. a pit hole in the street you avoid, math jumps in) and never happens in natural or technical systems.
