[blackcat] L2 Ehlers Rocket RSI IndicatorLevel: 2
Background
John F. Ehlers introuced Rocket RSI Indicator in May, 2018.
Function
In “RocketRSI—A Solid Propellant For Your Rocket Science Trading” in May, 2018, John Ehlers introduces a new take on the classic RSI indicator originally developed by J. Welles Wilder. Ehlers begins by introducing a new version of the RSI based on a simple accumulation of up and down closes rather than averages. To this he applies a Fisher transform. He tells us that the resultant output is statistically significant spikes that indicate cyclic turning points with precision.
With this indicator, overbought and oversold conditions are clear:
## Oversold Entry Condition: Indicator crosses value (RocketRSI crosses over -2.00)
## Overbought Exit Condition: Indicator crosses value (RocketRSI crosses under 2.00)
Note the used “crosses under 2.00” for the exit condition, rather than “crosses above 2.00.” This lets the winning positions ride further, and resulted in a better overall return in backtesting.

Readme
In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. 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. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.
Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.

This indicator does require some tinkering in cases to line up the waveforms. Here on the 4Hr I have used an RSI LB of 14 and SSF LB of 10.
Personally I find its better at picking short entries when the indicator is topping out. For bottoms it a bit less effective.
I do not use this indicator by itself, but rather as another tool when looking for short entries.
Description
The RocketRSI is an indicator that combines the approach used in the calculation of the Relative Strength Index (RSI) with some principles of signal processing and was developed by John Ehler. By smoothing out noisy price data and singling out a cyclic component within it, the indicator can be used for analysis of cyclic reversals, which could potentially signal trading
opportunities.
The calculation of the RocketRSI is as follows:
A close price change (momentum) from a past value is found for each bar. The offset between the current and the past price is constant.
The values found are run through Ehler
s 3-Pole SuperSmootherFilter to eliminate the noise.
The algebraic sum of one-bar changes in the filtered values is divided by the sum of absolute values of the same changes. The output of this step is limited to be in the range from -0.999 to +0.999.
The result is run through the Fisher transform to provide a easily interpreted wave-like output.
If there is a dominant cycle in the input data and the lengths are set correctly, the analysis of peaks and troughs of the output wave may provide valuable sell and buy signals.

Missile RSI (RSI of momentum w/ Dominant Cycle length + Fisher)This is a predictive indicator that looks for explosions in momentum of the cycles in price and large shifts in Momentum (Fisher turns the Bimodal PDF into Guassian like) as statistically unlikely events, showing points to exit or reverse positions.
You can adjust the lowpass frequency cuttoff (Aka what cycles you want to remove from the calculations through the super smoother filter).
To be honest you can monkey trade the direction of the Signal if you'd like but the Divergences and Maxing of the values is whats most useful.
Let me know if you guys want me to add anything else.
