Zentrading Trend Indicator v3.1This is a script for beta testing only. Based on ichimoku, but with slightly different behaviour, with many added features such as : trend detection, momentum detection, multiple time frame support/resistance levels, exhaustion/reversal signals. Used in conjunction with the other ZT indicators (ZT momentum, ZT CyclePhase, and ZT Volumebars) the strategy provides very distinct setups to trade for reversals, breakouts and pullbacks.

Roofing Filter [DW]This is an experimental study built on the concept of using roofing filters on price data proposed by John Ehlers. Roofing filters are a type of bandpass filter conventionally used in HF radio receivers in the first IF stage to limit the frequency spectrum passed on to later stages in the receiver. The goal in applying roofing filters to a price signal is to simultaneously attenuate high frequency noise and low frequency distortion to pass an oscillating signal with a nearly zero mean for analysis and/or further calculation. In this study, there are three filter types to choose from: -> Ehlers Roofing Filter, which passes data through a 2 pole high pass filter, then through a Super Smoother filter. -> Gaussian Roofing Filter, which passes data through a 2 pole Gaussian high pass filter, then through a 2 pole Gaussian low pass filter. -> Butterworth Roofing Filter, which passes data through a 2 pole Butterworth high pass filter, then through a 2 pole Butterworth low pass filter. Each filter type has different amplitude and delay characteristics, so play around with each type and see which response suits your needs best. There is an option to normalize the scale of the output as well. The normalization process in this script is computed by comparing positive and negative outputs to the filter's moving RMS value. The resulting oscillator can be fed through numerous conventional indicators including Stochastic Oscillator, RSI, CCI, etc. to generate smoother, less distorted indicators for a clearer view of turning points. Alternatively, it can also act as an indicator itself, as implied by the corresponding color scheme included in the script. Although roofing filters are not conventionally used in the analysis of market data, applying such spectral analysis techniques may prove to be quite useful for the design of more efficient indicators and more reliable predictions.

Low Pass Channel [DW]This is an experimental study designed to attenuate higher frequency oscillations in price and volatility with minimal lag. In this study, a single pole low pass filter is used. The low pass filter's cutoff period is determined either by a fixed user input, or by using an Instantaneous Frequency Measurement (IFM) algorithm. Most radar warning, electronic countermeasures, and electronic intelligence systems employ IFM to identify threats, map the electronic battlefield, and implement deceptive countermeasures. The IFM technique used for this study was devised by John Ehlers. It calculates In Phase and Quadrature (IQ) components using the Hilbert Transform and uses them to determine the dominant price cycle. To generate the channel, the same filter approach is applied to true range then added to and subtracted from the price filter. Custom bar colors are included for simple wave and trend indication.

BandPass EOS - 1hThis is a strategy i made for EOS Opens a long position if the PB line (the red line in the oscillator) crossover the low of the band, the zero line or the top of the band. If the PB line makes a crossunder in the top of the band, the zero line or the bottom of the band it closes the long position and immediately opens a short position. Also, the PB value must be higher than 5 candles before if it is a long position and PB must be lower than 5 candles before to open a short position I got the BandPass Script from www.tradingview.com and made some changes in the configs to adapt the strategy. If someone has any doubt i can answer below

MTF IQ IFM Moving AverageMTF ready adaptive MA using Ehler's IQ IFM ( In Phase - Quadrature Instantaneous Frequency Measurement ). Ehler's formula is a method of quantitatively measuring the length of a market cycle. In this case it is used to calculate the "optimal" adaptive EMA. Theoretically the length generated by Ehler's formula could be used in many indicators and it's been placed within it's own function so you should be able to simply copy/paste it. HOWEVER pine will not accept series variables for the length input used in built-in functions. You will have to manually code (or find) a version of your indicator that doesn't use the pine built in. Options : type : optionally add volume weighting range : historical range used in IQ IFM cycle length mult : method to create faster/slower MAs. eg 0.5 is half the length of a cycle and a faster EMA ie EMA10 vs EMA20 low sat fix : some cryptocurrencies with low satoshi values cause an issue with the calculation, if you get no/nonsensical lines, enable this. Shouldn't affect other instruments, but can be disabled just in case. MTF options: run the calculation on an alternative timeframe -------------------------------------- If you find it useful please consider a tip/donation : BTC - 3BMEXEDyWJ58eXUEALYPadbn1wwWKmf6sA

Center of Gravity Oscillator - Ehlers by KIVANC fr3762Center of Gravity OSCILLATOR by JOHN EHLERS Converted the original code from his book "Cybernetic Analysis for Stocks and Futures" This article describes a new oscillator that is unique because it is both smoothed and has essentially zero lag. The smoothing enables clear identification of turning points and the zero lag aspect enables action to be taken early in the move. This oscillator is the serendipitous result of my research into adaptive filters. While the filters have not yet produced the result I seek, this oscillator has substantial advantages over conventional oscillators used in technical analysis . The “CG” in the name of the oscillator stands for the Center of Gravity of the prices over the window of observation. The Center of Gravity ( CG ) of a physical object is its balance point. For example, if you balance a 12 inch ruler on your finger, the CG will be at its 6 inch point. If you change the weight distribution of the ruler by putting a paper clip on one end, then the balance point (e.g. the CG ) shifts toward the paper clip. Moving from the physical world to the trading world, we can substitute the prices over our window of observation for the units of weight along the ruler. With this analogy, we see that the CG of the window moves to the right when prices increase sharply. Correspondingly, the CG of the window moves to the left when prices decrease.

Ghosty's Modded Super Bandpass Filter [DasanC]Very cool Indicator from Ehlers and published originally by @DasanC I made minor modifications, and added a zero line and changed some values. I use this indicator differently then it is intended to be used for scalping shorter time frames (15 min - 1 hour). I use it like a cross over, either from the zeroline or when it passes the RMS, for 5-10 pips. While no indicator is 100% this one does a nice job for small scalps. try it out on a demo and see if you like it. enjoy. original Indy -

Profitable MAMA & FAMA CrossoverIntroduction The MESA Adaptive Moving Average (MAMA) was originally presented by John F. Ehlers. By design, it is a special kind of Exponential Moving Average with self-adjusting alpha. Its adaptation is based on the rate change of phase as measured by the Homodyne Discriminator and the alpha parameter is allowed to range between a maximum and minimum value (Fast Limit and Slow Limit). Key Point: Ehlers suggested the maximum value to be 0.5 and the minimum to be 0.05 . The variable alpha is computed as the Fast Limit divided by the phase rate of change. If the phase rate of change is large, the variable alpha is bounded at the SlowLimit. Then, this alpha is used to compute MAMA and FAMA (Following Adaptive Moving Average). Should we rely on Ehlers' suggestions if we want to achieve the best result with MAMA & FAMA crossover system? Well, he is a good specialist and widely recognized author, I respect him, but the answer is no and you can see results on the chart. What is our goal? We want to find the best configuration for MAMA & FAMA Crossover. To achieve that we need to analyze the MAMA's alpha parameter or, more specific, the bounds for this parameter, Fast and Slow Limits. What is this tool? This tool is a performance optimizer that uses decision tree-based algorithm under the hood to find the most profitable settings for the MAMA & FAMA Crossover. It analyzes a bunch of different Fast Limits (between 0.01 to 0.8 with step of 0.1 ) and Slow Limits (between 0.01 to 0.6 with step of 0.1 ) and backtests each combination across the entire history of an instrument. If the more profitable parameters were found, the indicator will switch its values to the found ones immediately. So, instead of manually selecting and testing parameters just apply this indicator to your chart and relax - the algorithm will find the best parameters for you Alerts It has a special alert that notifies when the more profitable settings were detected. NOTE: It does not change what has already been plotted. NOTE 2: This is not a strategy, but an algorithmic optimizer. Reference: www.mesasoftware.com MAMA & FAMA Crossover can be found here:

MTF Even Better Sine Wave - Dr. John EhlersThis is my enhanced "MTF Even Better Sine Wave" indicator using Pine Script version 4.0. This originates from the book "Cycle Analytics for Traders" written by Dr. John Ehlers in Chapter 12. While the original was simplistically designed, I enhanced it by adding a multitude of features Pine Script now accommodates. Most noticeably is the multiple time frame (MTF) features in the indicator "Settings". The three displayed indicators are using 5 second, 30 second, and 7 minute time frames. This may be the first PSv4.0 script to accommodate seconds in MTF adequately, but don't quote me on that. I haven't spent hours extensively looking for them. Be forewarned, second-based time frames are currently for Premium subscribers only, until such time in the future when the prerogative of TV might change. I will be adding second-based time frames to my other indicators where I feel it is beneficial to the indicator. Unlike Dr. John Ehlers' other Sinewave indicator that is intended for identifying turning points in cycling price fluctuations, the "Even Better Sine Wave", having stochastic like qualities, is intended for trending assets. Features List Includes: I.P.O.C.S.(Initial Public Offering Clean Start) Technology Enable/disable dark background for enhanced visibility "Source" selection with multiple time frame adjustments - including seconds "Duration" adjustment "Super Smoother BandEdge" adjustment "Display Area" selection for visual mutations displayed above Ranges and thresholds are enable/disable capable Upper threshold adjustment Lower threshold adjustment Adjustable centered medial zone Normalized zero mean to +/-1 This is not a freely available indicator, FYI. To witness my Pine poetry in action, properly negotiated requests for unlimited access, per indicator, may ONLY be obtained by direct contact with me using TV's "Private Chats" or by "Message" hidden in my member name above. The comments section below is solely just for commenting and other remarks, ideas, compliments, etc... regarding only this indicator, not others. If you do have any questions or comments regarding this indicator, I will consider your inquiries, thoughts, and concepts presented below in the comments section, when time provides it. When my indicators achieve more prevalent use by TV members, I will implement more ideas when they present themselves as worthy additions. As always, "Like" it if you simply just like it with a proper thumbs up, and also return to my scripts list occasionally for additional postings. Have a profitable future everyone!

Ehler's Super Smoother 2 and 3 pole (properly initialized)John Ehlers' Super Smoother 2 and 3 pole - properly initialized www.stockspotter.com Failure to properly initialize early values of the super smoother will result in misleading values early in the output. Because the SS is an IIR ( infinite impulse response) filter, this error can ring in the filter for a long time, but is extremely evident in the first 2*len bars. This is an implementation if the 2 and 3 pole SS filter, with special attention to initializing the early values. It uses (src+scr)/2 per Ehlers but contains code to just use src if you prefer to calculate that outside the function as everget does in his SS here: there is code included to make that change. Many thanks to everget for his terrific implementations of much of John Ehlers' work. It has been tremendously helpful to me.

Ehlers Decycler OscillatorThis indicator was originally developed by John F. Ehlers (Stocks & Commodities , V.33:10 (September, 2015): "Decyclers"). The idea is still the same as for the Simple Decycler. Mr. Ehlers suggested to virtually eliminate lag by getting rid of the very low-frequency components. So, he applied the high-pass filter to the simple decycler. Mr. Ehlers recommended to use two instances of the Decycler Oscillator with different parameters (high-pass filter period and multiplier). As a result, he got the Decycler Oscillator pair. The first oscillator (red line) has a period of 125 bars, the second one (yellow line) has a period of 100 bars. The interpretation is straightforward: When the yellow line crosses over the red line, a trend reversal to the upside is indicated. When the yellow line crosses under the red line, a trend reversal to the downside is indicated.
