Level: 2 Background John F. Ehlers introuced his DFT-ADAPTED RELATIVE STRENGTH INDEX (RSI) in Jan, 2007. Function In "Fourier Transform For Traders" in Jan, 2007, John Ehlers presented an interesting technique of improving the resolution of spectral analysis that could be used to effectively measure market cycles. Better resolution is obtained by a...
Level: 2 Background John F. Ehlers introuced his Stochastic RSI in August, 2006. Function John Ehlers' article in August, 2006, "Modeling The Market = Building Trading Strategies," describes a process for extracting trend and cyclic elements from market data, then recombining them for trading purposes. He used the Stochastic RSI denoted the cyclic...

Level: 2 Background John F. Ehlers introuced Hilbert Channel Breakout Trading System in Nov, 2000. Function This indicator will show how the adaptive filter is being applied to a trading strategy. After the Hilbert Channel Breakout Signal is optimized, set the inputs for this indicator to match the corresponding inputs for the signal. In the March 2000...
Level: 2 Background John F. Ehlers introuced the squelch indicator in Sep, 2000. Function This the squelch indicator code is identical to the Hilbert period code , with the addition of the squelch threshold and the display being implemented as a paintbar -- that is, a bar on the chart being colored, depending on the squelch threshold value. The Pine v4 code...
Level: 2 Background John F. Ehlers introuced swiss army knife (SAK)indicator in 2005. Function The swiss army knife (SAK)indicator does all the common functions of the usual indicators, such as smoothing and momentum generation. It also does some unusual things, such as band stop and band reject filtering. Once you program this indicator into your trading...
Level: 2 Background John F. Ehlers introuced Fractal Adaptive Moving Average (FRAMA) in 2004. Function The objective of using filters is to separate the desired signals from the undesired signals (or noise).
