Level: 2 Background John F. Ehlers introuced Recursive Median Oscillator in Mar, 2018. Function In “Recursive Median Filters” in Mar, 2018, John Ehlers presented an approach for filtering out extreme price and volume data that could throw off typical averaging calculations. Dr. Ehlers’ line in digital signal processing extends to removing extreme spikes in...
Level: 2 Background John F. Ehlers introuced Reverse EMA in Sep, 2017. Function In “The Reverse EMA Indicator” in Sep, 2017, John Ehlers presented very interesting filtering technique based on a Z-transform of the exponential moving average. It is a causal forward and backward EMA indicator that could be used in real trading. It has double smoothing at the...
Level: 2 Background John F. Ehlers introuced Super Passband Filter in Jul, 2016. Function In “The Super Passband Filter” in Jul, 2016, John Ehlers addressed the problem of frequencies in indicators that are too low or too high. The common practice to refine frequency is to enable smart filters. However, good filters take lots of computational power. So Ehlers...
Level: 2 Background John F. Ehlers introuced Decycler Oscillator in Sep, 2015. Function In “Decyclers” in Sep, 2015, John Ehlers described a method for constructing an oscillator that could help traders detect trend reversals with almost no lag, an oscillator that signals trend reversals with almost zero lag via digital signal processing techniques.
