Bridge Bands [joecat808]Bridge Bands are an implementation of the work done by Joe Catanzaro (joecat808) to produce a risk range for a security. The basic idea is to calculate Mandelbrot's "Bridge Range". (Pg. 179 of Misbehavior of Markets) It then calculates Bollinger Bands. Then next step is to calculate the Hurst Exponent. The last step is to merge the Bridge Range and the Bollinger Bands. The basic concept is if H = .5 we use the Bollinger Bands and the farther away we move from .5 in either direction the Bridge Range takes more precedent. There is a Trend value that is the mid-point of a 3 month Donchian Channel. If price is above we're bullish, if price is below we're bearish. Lastly, there is also an option info box with data regarding the underlying's position within the range, as well as an experimental position size calculation.

[blackcat] L2 Ehlers Fourier Series Strategy Level: 2 Background John F. Ehlers introuced Fourier Series Strategy in Jun, 2019. Function In “Fourier Series Model Of The Market” in Jun, 2019, John Ehlers introduces a Fourier series indicator designed to help traders identify cycles in the market. According to the author, the approach based on five principles outlined by J.M. Hurst in his 1970 book allows the determinization of a security’s primary cycle period and gives a faithful picture of market activity. It does so by applying a set of band-pass filters. His trading model’s rules are: ## 1. Buy next bar at market open when the FourierSeries(20) has reached a new 200-bar low and then turns up. This is an example of a “self-tuning” model, a concept we’ve been working with recently at Quantacula. Rather than establish an arbitrary oversold level, we use the historical data itself to look for an appropriate reversal level. ## 2. Sell at a limit price equal to the highest two-bar high. We’ve found that this exit works well to capture small gains in markets that are due for an upside move, while reducing exposure. Key Signal ROC --> Ehlers Fourier Series Strategy fast line Trigger --> Ehlers Fourier Series Strategy slow line 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. NOTE: I did not figure out how to improve this indicator's performance because is not so good as my expectation. Whatever, I just keep it 100% as Ehlers original work to inspire you. Remarks The 92th script for Blackcat1402 John F. Ehlers Week publication. 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.

Cycle Channel Oscillator [LazyBear]Here's an oscillator derived from my previous script, Cycle Channel Clone (). There are 2 oscillator plots - fast & slow. Fast plot shows the price location with in the medium term channel, while slow plot shows the location of short term midline of cycle channel with respect to medium term channel. Usage of this is similar to %b oscillator. The slow plot can be considered as the signal line. Bar colors can be enabled via options page. When short plot is above 1.0 or below 0, they are marked purple (both histo and the bar color) to highlight the extreme condition. This makes use of the default 10/30 values of Cycle Channel, but may need tuning for your instrument.
