[blackcat] L2 Ehlers SwamiCharts RSILevel: 2 Background John F. Ehlers introuced SwamiCharts RSI in his "Cycle Analytics for Traders" chapter 16 on 2013. Function SwamiCharts retain the core functionality of the technical indicators with which you're already familiar, while packing much more information into an easy-to interpret heat map chart. With SwamiCharts, you now visualize each indicator over a range of lookback periods to reveal a better view of the indicator's truer meaning in context. SwamiCharts provide a better solution because you can now visualize context over a wide range of lookback periods. Trends and cycles emerge more succinctly, while continuation patterns and reversals become easier to identify. SwamiCharts solves the data lookback problem by enabling you to view market conditions at a glance, a feature that will dramatically facilitate your trading. Since the MyRSI is computed for all values over the range of lookback periods, it must be an array in Pine v4.0 rather than a variable. The RSI is computed relative to the output of the roofing filter rather than price closes to eliminate the effects of Spectral Dilation. After the computation of the ratio, the indicator is smoothed in a SuperSmoother filter, so we must create the three most recent instances ourselves in the code. This is because Pine v4.0 retains historical values for variables but not for arrays. In fact, ratio must be an array also for the same reasons. The coefficients for the 10-bar SuperSmoother filter are computed and are the same for all lookback periods, and so can be outside the lookback loop to make the calculations a little more efficient.

[blackcat] L2 Ehlers Fisher Adaptive RSILevel: 2 Background John F. Ehlers introuced adding the Fisher Transform to the Adaptive RSI in his "Cycle Analytics for Traders" chapter 15 on 2013. Function The purpose of the Fisher transform is to take any indicator having a nominally zero mean and bounded between the limits of −1 to +1 and convert the amplitude so that the transformed indicator has an approximate normal probability distribution. The variable MyRSI ranges between zero and one, and therefore to accommodate the conditions for the Fisher transform, this variable must be translated and dilated to range between −1 and +1. If the MyRSI variable does not range fully between zero and one, you can shorten the RSI lookback period to be less than half the measured dominant cycle, or you can simply multiply it by a magnification factor as Dr. Ehlers have done in the code fragment. The amplifying factor was selected to make the indicator rarely exceed the two sigma points in the output. The amplified RSI is then limited to be within the range of −0.999 to +0.999 to avoid a computer crash, and then is used to compute the Fisher transform. The plus and minus two standard deviation levels are included in the indicator display.

Ehlers introuced Measuring the Dominant Cycle using the HomoDyne Discriminator in his "Cycle Analytics for Traders" chapter 14 on 2013. Function With Hilbert transformer, the third algorithm for computing the dominant cycle is the homodyne approach. Homodyne means the signal is multiplied by itself.

[blackcat] L2 Ehlers DC using the Phase AccumulationLevel: 2 Background John F. Ehlers introuced Measuring the Dominant Cycle using the Phase Accumulation in his "Cycle Analytics for Traders" chapter 14 on 2013. Function With Hilbert transformer, the next algorithm to compute the dominant cycle is the phase accumulation method. The phase accumulation method of computing the dominant cycle is perhaps the easiest to comprehend. In this technique, we measure the phase at each sample by taking the arctangent of the ratio of the quadrature component to the in-phase component. A delta phase is generated by taking the difference of the phase between successive samples. At each sample we can then look backwards, adding up the delta phases. When the sum of the delta phases reaches 360 degrees, we must have passed through one full cycle, on average. The process is repeated for each new sample. The phase accumulation method of cycle measurement always uses one full cycle's worth of historical data. This is both an advantage and a disadvantage. The advantage is the lag in obtaining the answer scales directly with the cycle period. That is, the measurement of a short cycle period has less lag than the measurement of a longer cycle period. However, the number of samples used in making the measurement means the averaging period is variable with cycle period. Longer averaging reduces the noise level compared to the signal. Therefore, shorter cycle periods necessarily have a higher output signal-to-noise ratio. Key Signal DomCycle --> Dominant Cycle Pros and Cons 100% John F.

Ehlers introuced Measuring the Dominant Cycle using the Dual Differentiator in his "Cycle Analytics for Traders" chapter 14 on 2013. Function With Hilbert transformer, the first algorithm to compute the dominant cycle is called the dual differentiator. In this case, the phase angle is computed from the analytic signal as the arctangent of the ratio of the imaginary component to the real component. Further, the angular frequency is defined as the rate change of phase. We can use these facts to derive the cycle period. Key Signal DomCycle --> Dominant Cycle Pros and Cons 100% John F.

[blackcat] L2 Ehlers Convolution IndicatorLevel: 2 Background John F. Ehlers introduced Convolution Indicator in his "Cycle Analytics for Traders" chapter 13 on 2013. Function Since high correlation exists only at the market turning point, the convolution indicator is dependent on the lookback period used in the calculation. Assuming the two price segments have an equal time duration, the peak correlation occurs at half the lookback period of the indicator. For example, if a 13-bar period is used, the market peak would appear with a 7-bar delay. The same market peak would appear with a 19-bar delay if a 39-bar lookback period were used in the convolution computation. Key Signal Convolution --> Convolution array Pros and Cons 100% John F.

[blackcat] L2 Ehlers Even Better SinwaveLevel: 2 Background John F. Ehlers introduced Even Better sinwave Indicator in his "Cycle Analytics for Traders" chapter 12 on 2013. Function The original Sinewave Indicator was created by seeking the dominant cycle phase angle that had the best correlation between the price data and a theoretical dominant cycle sine wave. The Even Better Sinewave Indicator skips all the cycle measurements completely and relies on a strong normalization of the waveform at the output of a modified roofing filter. The modified roofing filter uses a single-pole high-pass filter to deliberately retain the longer-period trend components. The single-pole high-pass filter basically levels the amplitude of all the cycle components that would otherwise be larger with longer wavelengths due to Spectral Dilation. Therefore, when the waveform is normalized to the power in the waveform over a short period of time, the longer wavelength contributions tend to be an indication to stay in a trade when the market is in a trend. The Even Better Sinewave Indicator works extraordinarily well when the market is in a trend mode. This means that the spectacular failures of most swing wave indicators are mitigated when the expected price turning point does not occur. Although Dr. Ehlers admitted he had not studied it extensively, it appears that the Even Better Sinewave Indicator works well on futures intraday data. It takes a position in the correct direction and tends to stay with the good trades without excessive whipsawing.

[blackcat] L2 Ehlers Adaptive CCI 2013Level: 2 Background John F. Ehlers introduced Adaptive CCI 2013 in his "Cycle Analytics for Traders" chapter 11 on 2013. Function The time length to be used for the channel in the calculations is widely varied in the literature. In all cases, the length is rather arbitrarily established to fit the indicator to some preconceived event. It seems to me that it would be better to use one full period of the dominant cycle as the length of data to be used. The adaptive CCI indicator starts with the computation of the dominant cycle using the autocorrelation periodogram approach. The identification of the indicator itself is noted by the comment near the end following the dominant cycle calculation. Since the objective is to use only those frequency components passed by the roofing filter, the variable Filt is used as a data input rather than the average of the high, low, and close as was done by Donald Lambert (Inventor of CCI).

[blackcat] L2 Ehlers DFT Spectral EstimateLevel: 2 Background John F. Ehlers introduced DFT Spectral Estimate in his "Cycle Analytics for Traders" chapter 9 on 2013. Function The DFT is accomplished by correlating the data with the cosine and sine of each period of interest over the selected window period. The sum of the squares of each of these correlated values represents the relative power at each period. The only user input is whether to select Spectral Dilation compensation. The default selection is NOT to use the compensation. The spectrum values vary between 0 and 1 after being normalized. These values are converted to colors. When the spectrum is greater than 0.5 the colors combine red and yellow, with yellow being the result when spectrum = 1 and red being the result when the spectrum = 0.5. When the spectrum is less than 0.5, the red saturation is decreased, with the result that the color is black when spectrum = 0. Key Signal DominantCycle --> Dominant Cycle signal Pros and Cons 100% John F. Ehlers definition translation of original work, even variable names are the same.

I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts. The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works. Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element. Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level. Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated. Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies.

DMI-ADX HistogramThe Average Direction Index (ADX) coupled with the Direction Movement Index (DMI), developed by J. Welles Wilder, is a popular indicator that measures trend direction and strength. The AX line (blue) is used to show the strength of the current trend. It does not tell you the trend direction. The under laid histogram shows relative movements of the price with green showing positive momentum and red showing negative momentum. Use these ADX and DMI together to find trend strength and direction. - ADX line below 20 indicates that the underlying is in accumulation/distribution. - ADX line above 20 mean that the underlying is trending with over 60 being very strong. *When the ADX line is below 20 it is likely to see many reversal signals on the DMI Histogram. It is best to use the DMI signals when the ADX line is above 20 or higher. This is also a good level to play around with. Motivation Normally the direction movements are plotted as lines with the DI+ being green and the DI- being red. When the DI+ (green) crosses over DI- (red) this may indicate a buy signal, and vice versa. I found this visual representation made it difficult to see signals as well as lacked the ability to easy see the relative strength of other moves. I have also noticed that the histogram values will periodically cross the ADX line, but not for very long periods. This could be a useful signal to explore further in the future. In this image the top indicator is using the normal DI+/- lines, where the bottom indicator is using an absolute histogram.

[blackcat] L2 Ehlers Autocorrelation ReversalsLevel: 2 Background John F. Ehlers introduced Autocorrelation Reversals in his "Cycle Analytics for Traders" chapter 8 on 2013. Function One of the distinctive characteristics of autocorrelation is that the autocorrelation shifts from yelow to red or from red to yellow at all values of lag at the cyclic reversals of the price. Therefore, all we need do to determine these reversals is to sum the bar-to-bar differences of the autocorrelation function across all values of lag. When the sum is large a turning point has been identified. The indicated reversals are very sensitive to the smoothing of the price data. Therefore, the LPLength is made available as an indicator input to decrease or increase the number of indicated reversals as desired. The AvgLength parameter is also made available as an indicator because this averaging also impacts the number of indicated reversals. Care should be taken when increasing the value of this input because the lag of the indicator increases in direct proportion to the increase of the value of the AvgLength. Typical delay of the indicator will be about three bars when the AvgLength parameter is set to a value of 3. The HPLength parameter is also made available as an input for complete flexibility of the indicator. However, changing its value has a relatively minor impact on the indicated reversals.
