Ehlers Stochastic Center Of Gravity [CC]The Stochastic Center Of Gravity Indicator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pgs 79-80), and this is one of the many cycle scripts that I have created but not published yet because, to be honest, I don't use cycle indicators in my everyday trading. Many of you probably do, so I will start publishing my big backlog of cycle-based indicators. These indicators work best with a trend confirmation or some other confirmation indicator to pair with it. The current cycle is the length of the trend, and since most stocks generally change their underlying trend quite often, especially during the day, it makes sense to adjust the length of this indicator to match the stock you are using it on. As you can see, the indicator gives constant buy and sell signals during a trend which is why I recommend using a confirmation indicator.
I have color-coded it to use lighter colors for normal signals and darker colors for strong signals. Buy when the line turns green and sell when it turns red.
Let me know if there are any other scripts you would like to see me publish!

Adaptive Fisherized Stochastic Center of GravityIntroduction
I modified the script "Fisher Stochastic Center of Gravity" of @DasanC for this indicator.
I added inverse Fisher transform, cycle period adaptiveness mode (Ehlers) and smoothing to it.
Moreover, I added buy and sell and beautified some stuff.
Lastly, it is also non-repainting!
Usage
This indicator can be used like a normal stochastic, but I don't recommend divergence analysis on it.
That fisherization stuff seems to make the graphs unuseable for that because it tries.
It works well on every timeframe I would say, but lower timeframes are recommended, because of the fast nature of stochastic.
Usually it does a good job on entry confirmation for reversals and trend continuation trades.
Recommended indicator to combine with this indicator is RSI cyclic smoothed v2 .
This is the best RSI version I know. In trending market it is recommended to look more on the inner bands and in flat market it is recommended to look more on the outer bands.
When RSI shows oversold and this indicator shows a crossover of the Center of Gravity plot through the bottom line -> Long entry is confirmed
When RSI shows overbought and this indicator shows a crossunder of the Center of Gravity plot through the top line -> Short entry is confirmed
Settings
The adaptive mode is enabled by default to give you straight the whole indicator experience.
The default settings are optimized, but should be changed depending on the market.
An example:
Market has a low volatility and a high momentum -> I want a slower/higher length to catch the slower new highs and lows.
Market has higher volatility and a low momentum, -> I want a faster/lower length to catch the faster new highs and lows
Signals
Crossover
Buy -> cog crossover signalLine
Sell -> cog crossunder signalLine
Overbought/Oversold Crossover
Buy -> cog crossover lowerBand
Sell -> cog crossunder lowerBand
I use this indicator a lot, because I don't know a better stochastic on this community here.
@DasanC did an awesome work with his version I used as base for this script.
Enjoy this indicator and let the profit roll! 🔥
GBT TunnelThis is a channel type tool I created, heavily influenced by LazyBear COG Fibs script and the COG Fibs script by Joy_Bangla which also uses LazyBear COG Fib logic. All credit to those guys, publishing this open source as well since its nothing here is my original work really.
COG SSMACD COL combo with ADX Filter [orion35]This indicator consists of a combination of indicators produced by the most valuable developers in the market.
These are: Center of Gravity (COG) and Super Smoothed MACD (SSMACD) shared by @KivancOzbilgic and Center of Linearity (COL) shared by @alexgrover
I produced this indicator by writing new conditions that compare the signals given by these indicators with each other. I re-coded the change in the thickness of the cloud from the COL indicator as the middle horizontal line with varying color intensity and type. I have provided options for switching between these three indicators when desired.
Note: The strongest signals in the indicator are the blue colored triangles. Moderately strong ones are yellow signals. White colored signals are considered as the weakest signals.
Some minor fixes:
Some confusing words were thrown in the alarms section,
Added new alarm codes for any Triple or Double signals.
Major changes have been made with this update.
It is very important to know the direction and strength of the trend in financial markets. Therefore, ADX (Average Directional movement index) was developed by J. Welles Wilder in 1978 as an indicator of the trend strength in the prices of a financial instrument.
Especially in sideways markets, most indicators produce many false signals. However, these signals can be filtered with the ADX indicator. The price is considered sideways when the ADX is less than 20 as the threshold value.
With this update,
ADX filter can be activated when desired, and signals can be filtered flexibly according to the "threshold" value determined by the user. When the ADX filter is active, it will also reflect on the alarm conditions. Therefore, if an alarm is to be set according to the ADX filter, the filter must be activated first.
The colors of the lines and signals have been made changeable.
The visual level and thickness of the COL line has been made adjustable.
With this update, signals can be filtered according to the MavilimW indicator developed by @KivancOzbilgic
Filter Methods:
Normal: If the price is below the BlueW line, "bull" signals are filtered out, and above "bear" signals are filtered out.
Reverse : Applies the opposite of the normal method.
Fixed some visual bugs in switching between indicators.
COG ContinuationsAutomatically finds Higher Lows and Lower Highs, which are useful for identifying Continuation entries.
This is not a standalone indicator and is meant to be used alongside a COG indicator, such as @veryfid's Boom Hunter (COG Mode) or similar.
KCGmut“KCGmut” stands for “Mutations Of Keltner Center Of Gravity Channel”.
After adding the ‘KeltCOG Width’ label to the KeltCOG, I got the idea of creating a subpanel indicator to show the development of the width-percent in previous periods. After some more thinking, I decided that the development of the COG-width-percent should also be reported and somehow the indicator should report whether the close is over (momentum is up), in (momentum is sideways) or under (momentum is down) the COG ( This is the gray area in the channel).
Borrowing from other scripts:
I tweeked the script of the KeltCOG (published) to calculate the columns and of REVE (also published) to calculate the volume spikes. Because the KeltCOG script had the default option to let the script chose lookback and adapt the width, I decided to not provide inputs to tweek lookback or channel width. Thus, if you use a KeltCOG in default setting, REVE and KCGmut together in the same chart, these will provide consistent complementary information about the candle. This layout has this combination:
I added actual volume to show where volume spikes occur.
Columns
For the channel-width-percent half of the value is used and for the COG-width-percent the whole to get a better image
By plotting the columns of the full width before those of the COG, in two series of positive and negative values, I created the illusion of a column with a different colored patch representing the COG (most are black) at the bottom where it points up (showing momentum is up), in the middle when the close is in the COG (no momentum) or at the top when the close is below the COG (showing momentum is down)
coloring drama
When nothing much happens, i.e. the channels keep the same width of shrink a bit, the columns get an unobtrusive color, black for the small COG patches and bluish gray for the channel columns pointing up or sideways, reddish gray when pointing down. If the COG increases (drama) the patches get colored lime (up), red (down) or orange (sideways, very seldom). If the channel increases, the columns get colored gold (up), maroon (down) or orange (sideways). Because the COG is derived from a Donchian channel, drama means a new high or low in the lookback period. Drama in the KeltCOG channel just means increase in volatility.
histogram showing volume spikes
Blue spikes indicate more then twice as much volume then recently normal, Maroon spikes indicate clear increases less then twice. To prevent the histogram from disappearing behind a column it is plotted first, spikes made longer then the column and also plotted both positive and negative. Single volume spikes don’t mean much, however if these occur in consecutive series and also come together with drama like new highs or increase in volatility, volume is worth noting. I regard such events as ‘voting’, the market ‘votes’ up or down. The REVE analyses these events to asses whether the volume stems from huge institutional traders (‘whales’) or large numbers of small traders (‘muppets’). This might be interesting too.
Remarks about momentum
Like in MACD, momentum has a direction. The difference is that in KCGmut momentum is a choise of the market to move above the COG (uptrend) or in (sideways) or under (downtrend), whereas in MACD the indicator shows the energy with which the market moves up or down. How does the market ‘choose’? The market doesn’t ‘think’, but still it comes to decisions. I see an analogy with the way a swarm of birds decides to go here or there, up or down, or land in a tree. All birds seem to agree but I guess a single bird has not much say in what the swarm does.
Boom Hunter ProBoom Hunter Pro is the ultimate indicator for targeting perfect long entries and epic shorts. Boom Hunter comes with a super fast oscillator that uses Ehlers Early Onset Trend (EOT). This is the Center Of Gravity Oscillator (COG) with a super smoothing filter and a roofing filter. This indicator is tuned for 1 hour charts but can be used on any time frame.
Colored bars can be turned on to assist in finding an entry. Purple signifies a drag and potential dump.
Fibonacci lines can be turned on to track price action and find entries/exit.
This indicator follows the same rules as COG. For more information please see my COG HOWTO here:
Center Of Gravity OscillatorThe COG Oscillator (center of gravity) is an indicator based on statistics and the Fibonacci golden ratio. It uses ALMA as a trigger and LSMA as "zero line". The trigger is set tight by default but can be tweaked by adjusting the window size and sigma in settings. This is a great indicator for setting up trades and spotting reversals. There are 2 main strategies that come with this indicator:
Strategy 1: Long positions are entered when current low point is higher than previous low. Short positions are entered as current high is lower than previous high. (Shown in image above)
Strategy 2 : If market is bullish long trades are entered as COG line crosses over red LSMA line. Traders have the option of scalping the first crossover or even scaling out of trade to close on second exit. This works the opposite for shorts when market is bearish.
Above shows different configurations of the indicator. Top shows length of 50, Middle has length of 21 and bottom is default 9.
Ehlers Adaptive Center Of Gravity [CC]The Adaptive Center Of Gravity was created by John Ehlers and this is a regular center of gravity indicator combined to be use with the current cycle period. If you are not familiar with stock cycles then I would highly recommend his book on the subject: Cycle Analytics. Buy when the indicator turns green and sell when it turns red.
Let me know if there are any other indicators you want me to publish!
Oscilator CandlesBased on the response received on Bollinger %B candles, thought it would be nice to get the same on oscillators.
Use cases include applying atr based indicators or any indicators which utilizes - high, low, open close on oscillator values. Example : supertrend
Note: length values are reused by different oscillator types based on input requirements.
Ehlers Center Of Gravity Oscillator [CC]The Center of Gravity Oscillator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 49) and this provides a pretty accurate way to see how the stock is trending. If the indicator stays above 0 then the stock is in a pretty strong uptrend and if it stays below 0 then the stock is in a pretty strong downtrend. Buy when the indicator changes from red to green and sell when it changes from green to red.
Let me know if you would like me to publish any other indicators or if you want something custom done!
ATR COG (Joy Bangla)Notes:
Black crosses indicate squeeze. It means an impending move once squeeze is released
Price tends to go from red dot to green dot to red dot to green dot to red dot in an endless cycle. We wait for the price bar to not touch the dots before we make a move
If the price goes between the dots and the lines, it means it is likely overheated/oversold respectively
If the price moves above the top line, it means the market is super overbought
If the price moves below the bottom line, it means the market is super oversold
This is an updated version 4 script from Lazy Bear's code as found from here
The update is there to ensure we can have alerts successfully set on Trading View
Ehlers Fisher Stochastic Center Of Gravity [CC]The Fisher Stochastic Center Of Gravity Indicator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 95) and this is a combo cycle indicator mixed with a stochastic indicator. The idea is to capture the beginning of the cycle and ride it until the end. Buy when the indicator line is green and sell when it turns red.
This was a custom request so let me know if you would like to see me publish any other scripts or if you want something custom done!
Center Of Linearity - A More Efficient Alternative To Elhers CGIntroduction
The center of gravity oscillator (CG) is one of the oscillators presented in Elhers book "cybernetic analysis for stocks and futures". This oscillator can be described as a bandpass filter centered around 0, its simplicity is ridiculous yet this indicator managed to get a pretty great popularity, this might be due to Elhers saying that he has substantial advantages over conventional oscillators used in technical analysis.
Today i propose a more efficient estimation of the center of gravity oscillator, this estimation will only use one convolution, while the original and other estimations use 2. I will also explain everything about the center of gravity oscillator, because even if its name can be imposing its actually super easy to understand.
The Center Of Gravity Oscillator
The CG oscillator is a bandpass filter, in short it filter high frequencies components as well as low frequency ones, this is why the oscillator is both smooth (no high frequencies) as well as detrended (no low frequencies), and therefore the oscillator focus exclusively on the cycles.
Its calculation is simple, its just a linearly weighted moving average minus a simple moving average wma - sma , this is not what is showcased in its book, but the result is just the same, the only thing that change is the scale, this is why some estimates have a weird scale that is not centered around 0, the output is technically the same but the scale isn't, however the scale of an oscillator isn't a big deal as long as the oscillator is centered around 0 and we don't plan to use it as input for overlay indicators.
If you are familiar with moving averages you'll know that the wma is more reactive than the sma, this is because more recent values have higher weights, and since subtracting a low-pass filter with another one conserve the smoothness while removing low-frequency components, we end up with a bandpass filter, yay!
Why "Center" Of Gravity ?
Elhers explain the idea behind this title with a pretty blurry analogy, so i'll try to give a visual explanation, we said earlier that the center of gravity was simply : wma - sma, ok lets look at their respective impulse responses,
Those are basically the weights of each filters, also called filter coefficients, lets denote the coefficients of the wma as a and the coefficients of the moving average as b . So whats the meaning behind center of gravity ? We basically want to "center" the weights of the wma, this can be done with a - b
The coefficients of the wma are therefore centered around 0, but actually there is more to that than a simple title explanation, basically a - b = c , where c are the coefficients of the center of gravity bandpass filter, therefore if we where to apply convolution to the price with c , we would get the center of gravity oscillator. Thats the thing with FIR filters, we can use convolution for describing a lot of FIR systems, and the difference between two impulse responses of two low-pass filters (here wma, sma) give us the coefficients of a bandpass filter.
The Center Of Linearity
At this point we could simply get the oscillator by using length/2 - i as coefficient, however in order to propose a more interesting variation i decided to go with a less efficient but more original approach, the center of linearity. Imagine two convolutions :
a = i*src and b = i*src
a only has a reversed index length-i , and is therefore describe a simple wma. Both convolutions give the following impulse responses :
Both are symmetrical to each others, and cross at a point, denoted center of linearity. The difference of each responses is :
Using it as coefficients would give us a bandpass filter who would look exactly like the Cg oscillator, this would be calculated as follows in our convolution :
i*src -i*src ) = i*(src -src )
Lets compare our estimate with the CG oscillator,
Conclusion
I this post i explained the calculation of the CG oscillator and proposed an efficient estimation of it by using an original approach. The CG oscillator isn't something complicated to use nor calculate, and is in fact closely related to the rolling covariance between the price and a linear function, so if you want to use the crosses between the center of gravity and 0 you can just use : correlation(close,bar_index,length) instead, thats basically the same.
The proposed indicator can also use other weightings instead of a linear one, each impulses responses would remain symmetrical.

Function To Candles - Another way to see indicatorsIntroduction
There are different and better way's to see price data, a candlestick chart is one of the best way to see the price since you have access to the open/high/low/close information, this is really efficient and can allow for naked non parametric trading strategies (candlesticks patterns) . But what about making candles out of indicators ? There are tons of studies about candlesticks patterns in price data but none (?) about candlestick patterns using indicator data, therefore i made this script in order to show candles from various indicators, i also made an heikin-ashi mode.
Rsi To Candles
All the indicators are use the open/high/low/close price as input in order to return candles. length control the indicator period.
Stochastic To Candles
The stochastic oscillator is restrained in a range of 0/100, therefore when equal to 0 or 100 the candles can be flat.
Rate Of Change To Candles
The rate of change don't distort price as heavily as other indicators since its based on differencing.
Center Of Gravity To Candles
The center of gravity (cog) is defined from tradingview as "an indicator based on statistics and the Fibonacci golden ratio", its not an indicator i'am familiar with and i don't know if its the same proposed by Elhers. The candles are smooth, high length can flatten the candles heavily making them hard to see.
Correlation Oscillator
In a range of -1/1 this indicator is quite smooth and can also flatten candles.
Patterns And Heikin-Ashi
There are tons of patterns that can be generated from candlesticks, they can be applied to this indicator as well.
The indicator can show an heikin-ashi mode, heikin-ashi candlestick use averaging to plot candles, this is why they appear smoother, some signals generated from heikin-ashi candles are :
Bullish body with no lower shadows = Strong Uptrend
Bearish body with no higher shadows = Strong Downtrend
High range and small body = Indecision/Risk of reversal
Conclusion
I made an indicator able to draw candles from other indicators, those candles contain various information that can generate decision from patterns. I hope you find a use to it, if its the case share your findings with me, maybe that you will even be able find a new candlestick pattern :)
