DFT - Dominant Cycle Period 8-50 bars - John EhlerThis is the translation of discret cosine tranform (DCT) usage by John Ehler for finding dominant cycle period (DC). The price is first filtered to remove aliasing noise(bellow 8 bars) and trend informations(above 50 bars), then the power is computed. The trick here is to use a normalisation against the maximum power in order to get a good frequency resolution. Current limitation in tradingview does not allow to display all of the periods, still the DC period is plot after beeing computed based on the center of gravity algo. The DC period can be used to tune all of the indicators based on the cycles of the markets. For instance one can use this (DC period)/2 as an input for RSI. Hope you find this of some interrest.

Better RSI with bullish / bearish market cycle indicator This script improves the default RSI. First. it identifies regions of the RSI which are oversold and overbought by changing the color of RSI from white to red. Second, it adds additional reference lines at 20,40,50,60, and 80 to better gauge the RSI value. Finally, the coolest feature, the middle 50 line is used to indicate which cycle the price is currently at. A green color at the 50 line indicates a bullish cycle, a red color indicators a bearish cycle, and a white color indicates a neutral cycle. The cycles are determined using the RSI as follows: if RSI is overbought, cycle switches to bullish until RSI falls below 40, at which point it becomes neutral if RSI is oversold, cycle switches bearish until RSI rises above 60, at which point it becomes neutral a neutral cycle is exited at either overbought or oversold conditions Very useful, please give it a try and let me know what you think

Hurst Exponent Market Phases [DW]This study is an experiment designed to identify market phases using changes in an approximate Hurst Exponent. The exponent in this script is approximated using a simplified Rescaled Range method. First, deviations are calculated for the specified period, then the specified period divided by 2, 4, 8, and 16. Next, sums are taken of the deviations of each period, and the difference between the maximum and minimum sum gives the widest spread. The rescaled range is calculated by dividing the widest spread by the standard deviation of price over the specified period. The Hurst Exponent is then approximated by dividing log(rescaled range) by log(n). The theory is that a system is persistent when the Hurst Exponent value is above 0.5, and antipersistent when the value is below 0.5. The color scheme indicates 4 different phases I found to be significant in this formula: - Stabilization Phase - Destabilization Phase - Chaos Increase Phase - Chaos Decrease Phase This script includes two visualization types to choose from: - Bar Counter Mode, which displays the number of bars the exponent is consecutively in each phase. - Hurst Approximation Mode, which displays the approximated exponent value. Custom bar colors are included. Please note: This is a rough estimate of the Hurst Exponent. It is not the actual exponent. Numerous approximations exist, and their results all differ slightly.

Hurst Cycle Channel Clone [LazyBear]Cycle Channel is loosely based on Hurst's nested channels. Basic idea is to identify and highlight the shorter cycles, in the context of higher degree cycles. This indicator plots the shorter term (red) & medium term (green) cycles as channels. Some things to note: As you can see the red channel keeps moving with in the bounds of green channel. When green breaches red channel, it usually signifies extreme market condition. Both red & green channels provide support/resistance levels. Also, the green channel provides S/R levels to the inner red channel. Movement of red channel with reference to green highlights reversal points, reducing momentum et al. For ex., point "(x)" in the chart shows how red channel failed to reach the upper green channel line and highlighted the local top. Use this just like other bands/channels. I have more indicators derived from this idea, will post them later.
