[blackcat] L2 Ehlers Classic Hilbert Transformer

Level: 2

Background

John F. Ehlers introuced Classic Hilbert Transform in his "Cycle Analytics for Traders" chapter 14 on 2013. The Hilbert Transform is a procedure to create complex signals from the simple chart data familiar to all traders. Once we have the complex signals, we can compute indicators and signals that are more accurate and responsive than those computed using conventional techniques. In fact, some of the indicators we will discuss cannot be calculated at all without the Hilbert Transform.


Function
blackcat L2 Ehlers Hilbert Transform indicator performs basic Hilbert Transform ( HT ) from chart data source and generate complex IQ data.


Key Signal

Imag --> Quadrature phase output signal
Real --> In-phase output signal

Pros and Cons

100% John F. Ehlers definition translation, even variable names are the same. This help readers who would like to use pine to read his book.

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.

Kommentarer

These Ehler's scripts are pretty cool. I believe the guy has some incredible ideas, but at the same time, I think of his ideas as starting points. The reason I say that is it seems he's a solid mathematician and has a real handle on physics. He understands and communicates the math behind it really well. His books are dense and fun to decipher. On the whole, his stuff is amazing. Guys like me who are not as adept in those skills love his contributions to the trading community because its exactly the direction we want to go with our trading; that is to have in our arsenal real measurements that can be relied on and are grounded in science.

But, now this is just my opinion, Ehler doesn't seem to really apply these ideas to markets in a way that shows the same handle on markets and trading tools that he has on math and physics. Seems you've studied him pretty closely. Would you agree with this assessment? and do you use his indicators in your everyday trading as he wrote them?
(Thanks for sharing them to tradingview btw. A lot of guys can't translate EL -> Pine)

@kurtsmock, thanks for sharing your insights. I fully agree with you. i am using some of his indicators as basic elements in my l4/l5 indicators. I am still exploring the advanced usage of his indicators as well. I may publish some of ideas in the future and you will see how it works.
