Ehlers Cycle BandPass Filter [CC]The Cycle BandPass Filter was created by John Ehlers (Cycle Modes and Trend Modes) and this is an alternate to the default BandPass Filter by changing some settings. This will be another series I will be introducing showing some indicators created by Ehlers and that didn't get much attention. This identifies the underlying cycle in the price data and these indicators aren't very common so I want to introduce more of these to tv. Buying and selling with these indicators can be a bit tricky but overall what Ehlers recommends is to buy at the lowest point and sell at the highest point to capture the underlying cycle. I have included strong buy and sell signals as darker colors and normal signals as lighter colors. Buy when the line turns green and sell when it turns red.

Ehlers Instantaneous Phase Dominant Cycle [CC]The Instantaneous Phase Dominant Cycle was created by John Ehlers (Stocks & Commodities V. 18:3 (16-27)) and this is one of many similar indicators that I will be publishing from Ehlers in the next few months that calculate the current dominant cycle period. The cycle period can be used in multiple ways but generally this means that if the stock is currently at a low then the current cycle period will tell you when the next lowest low will get hit or vice versa. This is also useful for using this cycle period as an input for other indicators to provide a very good adaptive length. Let me know how you wind up using these indicators in your daily trading. I have included the same buy and sell signals from my recent Hilbert Transform and so buy when the line turns green and sell when it turns red.

Ehlers Hilbert Transform [CC]The Hilbert Transform was created by John Ehlers (Stocks & Commodities V. 18:3 (16-27)) and this indicator can work pretty well as a trend confirmation. This essentially transforms the underlying price data into a soundwave and when you compare the two (blue is positive and red is negative) then it provides fairly clear buy and sell signals. Ehlers did warn in his original article that this indicator has a lag of 4 bars so you have to keep that in mind. I have found that this indicator works pretty well when you buy when the blue line goes over the red line and sell when the blue lines hits the zero line. You could also ignore the red line and buy when the blue line crosses over the zero line and sell when it crosses under. Let me know how you wind up using this indicator in your trading.

Ehlers Squelch Indicator [CC]The Squelch Indicator was created by John Ehlers (Stocks & Commodities V. 18:9 (42-46)) and this indicator is a variation of his Market Mode Indicator and its purpose is the same as in it determines if the market is trending or in a choppy market. If this indicator is at the 1 level then this means the market is trending and if it is at 0 then the market is choppy. I would recommend to adjust the squelch variable to find a setting that works well for you. If you want to avoid more choppy markets then adjust the squelch variable to a lower amount and vice versa. I have included basic buy and sell signals so buy when the line turns green and sell when it turns red.

Ehlers Simple Window Indicator [CC]The Simple Window Indicator was created by John Ehlers (Stocks and Commodities Sep 2021) and this is the last of the 4 new indicators that he published in the latest issue of Stocks & Commodities. Since these are all part of a series, the idea behind each indicator is the exact same. The only difference is of course the calculation for each indicator. This script is different mostly because it is extremely noisy in comparison so I had to smooth it twice to provide clear buy and sell signals. Window functions are used in digital signal processing to filter out noise and the end result is an oscillator that centers around the 0 line. The easy way to understand these indicators that I will be publishing and those are that when they are above 0, it usually means an uptrend and below 0 then a downtrend. For more immediate signals, I have included both normal and strong buy and sell signals so darker colors for strong signals and lighter colors for normal signals. Buy when the line turns green and sell when it turns red.

Ehlers Triangle Window Indicator [CC]The Triangle Window Indicator was created by John Ehlers (Stocks and Commodities Sep 2021) and this is one of 4 new indicators that he published in the latest issue of Stocks & Commodities and I will be publishing the last one tomorrow. Since these are all part of a series, the idea behind each indicator is the exact same. The only difference is of course the calculation for each indicator. Window functions are used in digital signal processing to filter out noise and the end result is an oscillator that centers around the 0 line. The easy way to understand these indicators that I will be publishing and those are that when they are above 0, it usually means an uptrend and below 0 then a downtrend. For more immediate signals, I have included both normal and strong buy and sell signals so darker colors for strong signals and lighter colors for normal signals. Buy when the line turns green and sell when it turns red.

Ehlers Hamming Window Indicator [CC]The Hamming Window Indicator was created by John Ehlers (Stocks and Commodities Sep 2021) and this is one of 4 new indicators that he published in the latest issue of Stocks & Commodities and I will be publishing the other 2 in the next few days. Since these are all part of a series, the idea behind each indicator is the exact same. The only difference is of course the calculation for each indicator. Window functions are used in digital signal processing to filter out noise and the end result is an oscillator that centers around the 0 line. The easy way to understand these indicators that I will be publishing and those are that when they are above 0, it usually means an uptrend and below 0 then a downtrend. For more immediate signals, I have included both normal and strong buy and sell signals so darker colors for strong signals and lighter colors for normal signals. Buy when the line turns green and sell when it turns red.

Ehlers Hann Window Indicator [CC]The Hann Window Indicator was created by John Ehlers (Stocks & Commodities Sep 2021) and this is one of 4 new indicators that he published in the latest issue of Stocks & Commodities and I will be publishing the other 3 in the next few days. Since these are all part of a series, the idea behind each indicator is the exact same. The only difference is of course the calculation for each indicator. Window functions are used in digital signal processing to filter out noise and the end result is an oscillator that centers around the 0 line. The easy way to understand these indicators that I will be publishing and those are that when they are above 0, it usually means an uptrend and below 0 then a downtrend. For more immediate signals, I have included both normal and strong buy and sell signals so darker colors for strong signals and lighter colors for normal signals. Buy when the line turns green and sell when it turns red.

FIR Hann Window Indicator (Ehlers)From Ehlers' Windowing article:
"A still-smoother weighting function that is easy to program is called the Hann window. The Hann window is often described as a “sine squared” distribution, although it is easier to program as a cosine subtracted from unity. The shape of the coefficient outline looks like a sinewave whose valleys are at the ends of the array and whose peak is at the center of the array. This configuration offers a smooth window transition from the smallest coefficient amplitude to the largest coefficient amplitude."

Indicator added twice to chart show both FIR and ROC.
Ehlers Convolution Indicator [CC]The Convolution Indicator was created by John Ehlers (Cycle Analytics For Traders pgs 170-174) and this is version of an indicator to find potential reversal points. The idea behind this indicator is to use a variation of his AutoCorrelation Indicator that transforms the data using digital signal processing and as you can see it looks very similar to his BandPass Filter . The idea is that when this indicator peaks then it has reached a potential reversal point and so the stock may continue in the current direction but most of the time this indicator correctly points out the reversal points. I have included normal buy and sell signals but generally speaking you would want to buy when the indicator is around 0.05 to 0.10 and moving up and sell when it reaches its peak and is starting to move down.

Ehlers Optimum Predictor [CC]The Optimum Predictor was created by John Ehlers (Rocket Science For Traders pgs 209-210) and this indicator does a pretty good job of predicting major market moves. When the blue line crosses over the red line then this indicator is predicting an upcoming uptrend and when the blue line crosses under the red line then it is predicting an upcoming downtrend. Ehlers recommends using this indicator with an entire trading system to filter out any bad signals but most of the signals it gives are pretty accurate. He uses advanced digital signal processing to predict the future prices and uses it in an ema formula for the calculation. There are several ways to interpret this indicator: you can look for crossovers, you can also look for when the indicator goes above 0 for a general uptrend or below 0 for a general downtrend.

Ehlers Market Mode Indicator [CC]The Market Mode Indicator was created by John Ehlers (Rocket Science For Traders pgs 114-117) and this is a handy tool that will tell you if the market is currently in a cycle or a trend. When the current market is in a cycle or choppy state then the indicator will read 0 and when it is in a trend then it will read 1. He uses some advanced digital signal processing to figure out the current trend and for how long it has been trending. I have included buy and sell signals using the trendline and so buy when the line turns green and sell when it turns red. Let me know if this indicator is useful for you.

TEMA/MAMA CrossThis is a strategy based on the TEMA and Ehler's MAMA moving averages. Crosses of the fast and slow TEMA are commonly used for entry and exit strategies. The Ehler's Mesa Adaptive Moving Average is a trend-following price indicator that uses a Hilbert Transform. Having plotted both TEMA and eMAMA side-by-side for some time, I noticed a pattern where the fastTEMA crossed over the eFAMA (eFAMA is the Ehler's MAMA following/slow MA) prior to a price increase. This is a strategy to test that observation.
The strategy (at present) only does long entries. It enters long when the fastTEMA crosses up over the (slow) eFAMA. It uses a traditional exit when the fastTEMA crosses below the slowTEMA. I have tested this on several tokens on 1hr charts using a fastTEMA length of 13. Play with it on different charts and different lengths to see how it works for you.
Ehlers Relative Vigor Index [CC]The Relative Vigor Index was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 58) and this is a momentum indicator that is similar to the Accumulation Distribution Oscillator created by Jim Waters and Larry Williams. He uses digital signal processing to smooth the indicator to provide clear buy and sell signals. The idea behind this indicator is that during uptrends, prices tend to close near the high and during downtrends, prices tend to close near the low. I have included strong buy and sell signals in addition to normal ones so strong signals are darker in color and normal ones are lighter in color. Buy when the line turns green and sell when it turns red. Usually the best signals I have found for this indicator is when the indicator is below the 0 line and turns green then it is usually a sign of a strong uptrend.

Ehlers Adaptive Bandpass Filter [CC]The Adaptive Bandpass Filter was created by John Ehlers (Cycle Analytics For Traders pgs 153-156) and this uses his autocorrelation code to provide the adaptive lengths to use for the underlying bandpass filter. The bandpass filter is a common way in digital signal processing to filter out the underlying noise in the data. It can actually be turned into a leading indicator by changing the bw variable to a smaller amount. Since this indicator is adaptive using the cycle period, the buy and sell signals are different compared to the normal bandpass filter. Buy signals for this indicator according to Ehlers are when the line is red and the line is under the oversold line (also red) then you buy when the indicator line turns green and then you exit when the indicator line turns red and is above the overbought line. This indicator doesn't provide clear buy and sell signals in all circumstances but generally speaking buy when the indicator line turns green and sell when it turns red. Feel free to experiment with this one.

Ehlers Adaptive Stochastic Indicator V1 [CC]The Adaptive Stochastic Indicator V1 was created by John Ehlers (Rocket Science For Traders pgs 233-234) and this indicator uses the same calculations to find a cycle period that is then used for both the creation of the stochastic indicator but also for the smoothing to create a double smoothed stochastic indicator. Because it is calculated this way, this indicator is more reactive than almost any other stochastic indicator and provides clear buy and sell signals especially when the underlying stock is trending. It is interpreted in the same way as a normal stochastic indicator so great buy signals are when the indicator is below the oversold line and starts to move up and vice versa. Buy when the line turns green and sell when it turns red.

MESA Stochastic Multi LengthJohn Ehler's MESA Stochastic uses super smoothing to give solid signals. This indicator uses the same rules as every other Stochastic indicator so it would be worth looking into if you are not already familiar with reading a Stochastic. There are 4 different lengths displayed to give traders an edge on reading the market. This is a great tool to analyze waves and find tops and bottoms. It gives great pump and dump signals and even helps filter out bad trades when used with other indicators such as Boom Hunter.
Below are some examples of signals to look out for:

Ehlers Modified Relative Strength Index [CC]The Modified Relative Strength Index was created by John Ehlers (Cycle Analytics For Traders pgs 87-88) and this is a typical RSI that uses his roofing filter as the input. He smooths it with his own super smoother filter to provide signals. This indicator is extremely reactive and works in cycles so keep that in mind. I haven't been able to come up with clear buy and sell signals at this point so let me know if you any suggestions but I'm publishing the code to complete my goal of publishing all of his work one day. I will be publishing a bunch of Ehlers scripts in the next few weeks so stay tuned. What I recommend for buy and sell signals at this point are to buy when the indicator goes below the oversold line and starts going up and sell when the indicator goes below the oversold line a second time. Vice versa for sell signals.

Ehlers AutoCorrelation Indicator [CC]The AutoCorrelation Indicator was created by John Ehlers (Cycle Analytics pgs 94-98) and this can be viewed as both a momentum indicator and a trend indicator. This was his basis for several other indicators that he created which I will be publishing soon but essentially as this indicator goes up then the stock is in an uptrend and also has upward momentum. You will notice that this indicator starts to go down even during an uptrend showing that the underlying trend is going to have an upcoming reversal. He also warns that the halfway mark is a possible reversal point so keep an eye out for that.
Generally speaking a good signal is to enter a long position when the indicator is under the midline and is starting to go up (or when the line is green) and to exit the position when the indicator goes over the midline. I have included strong buy and sell signals in addition to normal ones so darker colors mean strong signals and lighter colors mean normal signals.

Ehlers Adaptive Relative Strength Index V1 [CC]The Adaptive Relative Strength Index was created by John Ehlers and this is his first version. I will of course publish his updated version at a later date along with publishing the final script from Jim Sloman's Ocean Theory book. I have changed his script to include extra smoothing to provide clear buy and sell signals. This is a version of a RSI that is very adaptive to changes by finding the length of the current cycle and using that to calculate the rsi and I use this same basic process to provide extra smoothing. A great strategy of course is to buy right after the indicator goes from below the oversold level to right above it and stay in until the indicator turns red or when it reaches the overbought level. I have included strong buy and sell signals in addition to normal ones and the darker colors mean strong signals and lighter colors are normal signals.

Ehlers Distance Coefficient Filter [CC]The Distance Coefficient Filter was created by John Ehlers and this is one of his more unknown moving averages. It works well because in an uptrend or downtrend it behaves more like a trailing stop system but it also deals with issues like pullbacks pretty quickly. I think it works well with the default values but let me know if you find a more profitable system. Buy when the indicator turns green and sell when it turns red.

Ehlers Smoothed Adaptive Momentum [CC]The Smoothed Adaptive Momentum indicator was created by John Ehlers and this indicator gives a lot of useful information. When the indicator is above 0 then there is very strong upward momentum and when the indicator falls below 0 then there is very strong downward momentum. A very profitable way to use this particular indicator is buy long when the indicator is below 0 and it crosses over it's signal line and then sell of course when you get the first sell signal. I have included strong buy and sell signals in addition to normal ones so darker colors mean strong signals and lighter colors are normal signals. Buy when the line turns green and sell when it turns red.
Let me know if you have any other scripts you would like to see me publish!
Ehlers Simple Clip Indicator [CC]The Simple Clip Indicator was created by John Ehlers (Stocks and Commodities June 2021 pg 10) and this is obviously very similar to the previous indicator I published ( Ehlers Simple Deriv Indicator ) so I would recommend to try both out and see what you prefer. This is a new momentum indicator that is extremely responsive to price changes and when the indicator is above 0 then this means the stock is in a long term uptrend and when it is below 0 then it is in a long term downtrend. I have color coded the indicator line to show you both strong buy and sell signals and normal buy and sell signals. Dark colors are strong signals and of course green means a buy signal and red means a sell signal. I did change the original buy and sell signals that Ehlers included in his scripts because I didn't find that they worked very well so let me know what you think of my changes.
