Let's discuss Community Indicators here.

To start, it's just been updated to version 2009.01. Added LaguerreRSI, TD REI, Density of Consolidation, Gann Swing Oscillator and a fully configurable version of MACD Signal.

More details by this link.

Suggest your candidates to be included in the library, it's community-driven!

Community.Indicators are updated to version 2009.02 and will now include:

* The Adaptive Lookback (Period Finder) indicator - highly universal 'adaptivity engine' for many indicators, bands, channels etc. We'll be covering its application in future Active Trader Mag issues.
* Martin Pring's Special K Daily and Special K Weekly indicators
* VK Bands and VKW Bands
* Trend Quality
* Community requested: Sqrt (Square root of series), Time Series Forecast and variable-length Ultimate Oscillator

Community.Indicators updated to version 2009.03:

Added: Adaptive Laguerre filter
Fixed: Rolled back the 2009.02 Description change for indicators that use a Bars object parameter. The change was not necessary and adversely affected the utility of the Analysis Series visualizer.

In this unscheduled update 2009.03.10, we include some more indicators and helpers:

Added: Beta
Added: LNRet + VarianceRatio /by Dr.Koch/
Added: Consecutive Days Up + Consecutive Days Down /by Glitch/
Added: Series is above /by Cone/ + Series is below

Community Indicators Pack 2009.04 was uploaded --

Added: Trend Intensity Index (TII)
Added: Power and Log (requested by ss161)
Added: Keltner ATR bands (requested by Algotrader)
Added: ATR bands
Added: The Tenkan Sen and the Kijun Sen to the already existing Senkou Span A and Senkou Span B (Ichimoku)
Added: Excel Correlation (created by Michael Bytnar) and Correlation (created by Steve Salemy)
Fixed: Dreiss Choppiness index (description string)

Service release 2009.04.2 --

* Fixed: Dynamic Momentum Indicator aka DyMoI - extraneous paramer removed (thanks to zentek)
* Fixed: Completely reverted the 2009.02 change to indicator description string (Analysis Series breaking)

I have downloaded and really like your new Community Indicators, especially the option to put in your own parameters for MACD.
However, would it be possible to add another option to parameters and give one the choice of using EMA or SMA for MACD?
I am trying to incorporate Linda Bradford Rasche's MACD settings, but I am not a programmer and your new MACD with user EMA settings gets me a little closer.
Appreciate your consideration of incorporating SMA as an option for the MACD.

Thanks. Sorry, adding another option to such a popular indicator like MACD_Ex would not be a good move because it will break backward compatibility and force other people who are already using it to make fixes to their Strategy code.

What's more, adding another MACD_Ex indicator will make the Indicator list look confusing. Considering that your request for SMA in MACD is the only one, maybe we will better call it "Linda Raschke's 3/10 Oscillator" or something like that? In this case, I see no problem including what you want in the upcoming build of Community.Indicators.

Yes, my primary interest is in the "3/10" with HIstogram, Your inclusion of the Raschke 3/10 Oscillator with HIstogram as a separate indicator in future builds would be welcomed. Thanks.

2009.05

* Added: Linda Raschke's 3/10 Oscillator (requested by chuy)
* Added: John Ehlers' Sine Wave indicator (created by DartboardTrader)
* Fixed: Adaptive Lookback formula optimizations (thanks to Robert for the heads-up)
* Fixed: Gann Swing Oscillator formula

2009.06

* Added: Elder SafeZone Stop Long and Elder SafeZone Stop Short

2009.07 is here

The most notable news is the addition of the missing Hilbert Transform filters (the complete set of Ehlers filters ported from WL4 - thanks to fundtimer): HTDCPhase, HTInPhase, HTLeadSin, HTPeriod, HTQuadrature, HTSin, HTTrendLine

Also, added TrendScore by Tushar Chande; Coppock curve; Widner Projection Bands and its companion indicators.

Release 2009.08 highlights:

* Added: Shifted Moving Average
* Added: The ShiftDelay indicator
* Added: DV2 by D.Varadi (coded by Robert Sucher)

The Shifted MA and ShiftDelay indicators were developed by request (here).

The purpose of ShiftDelay is to easily create a delayed version of any indicator or data series already plotted on the chart. The ShiftedMA is targeted for rule-based Strategy users who need to utilize a typical moving average delayed by the user specified offset.

How do I access these extensions/indicators in a strategy?

I am trying to take the log ratio of 'close' values:

CODE:
Please log in to see this code.

The name 'log' does not exist in this context

Just like with absolutely any other indicator e.g. SMA:

CODE:
Please log in to see this code.

It would be very helpful if the MACDEx_Signal3 data from a chart can be exported using "Copy Price Data to Clipboard", like other standard indicators. Thanks.

It is already possible. Add the indicator, right click, select that option and the indicator data is copied to clipboard along with OHLCV.

My program told me extension was installed successfully but I do not see it in Extension Manager. Hence the same error continues? I restarted Wealth-Lab, etc.

It is there, you just need to switch from Fidelity supported to Other extensions. Of course I assume you have included "using Community.Indicators" on top, did you?

Release 2009.09 highlights:

* Added: DV2 bounded by D.Varadi (coded by Michael Bytnar)
* Added: BBandUpper2/BBandLower2 -- Bollinger Bands that allows to select calculation type: Sample or Population (by request of dansmo)
* Added: Moving Average Envelope (by request of hamblin1) - typical MA envelopes like in ActiveTrader Pro
* Fixed: TII

Note that starting from this build, the Extension won't install itself in Wealth-Lab 5.1-5.3 (update to 5.4).

Here's what has been added to 2009.10:

* Added: DV Super Smoothed Double Stochastic Oscillator (DVSSDSO) by D.Varadi
* Added: Geometric and Arithmetic Mean Divergence Oscillator (GAMDO) by D.Varadi
* Added: PercentRank (coded by Michael Bytnar)
* Added: True Strength Index (TSI) by W.Blau
* Added: HiLoLimit by Dr.Koch (coded by thodder)

MACDEx users! This indicator from Community Indicators has a breaking change in the current version 2010.09. MACDEx and its derivative indicators used in rule-based or code-based strategies alike before 6.0, will result in a compiler error.

Solution: for code-based strategies - remove an extraneous Bars parameter (check out the online help pages in the Wiki); for Rule Wizard - simply highlight an affected condition (that uses MACDEx or one of its derivatives) and re-select MACDEx (Histogram, etc.) from the Indicators list > Community Indicators.

A bunch of breaking changes to a few indicators in 2010.10:

* Added: McClellan Oscillator
* Added: choice of SMMA (smoothed MA) to ShiftedMA
* Added: SeriesIsAboveValue, SeriesIsBelowValue
* Change: breaking change to DVCFE - added configurable PercentRank period
* Change: breaking change to Negative Closes - replaced Bars parameter with DataSeries
* Change: breaking change to Positive Closes - replaced Bars parameter with DataSeries
* Change: breaking change to Percentage Price Oscillator (PPO) - replaced Bars parameter with DataSeries; changed FirstValidValue to 3 times the largest lookback period (to stabilize)
* Fixed: hardcoded DVCFE periods
* Fixed: important fix to Bill Williams' Alligator Jaw, Teeth and Lips. Now they will use the correct moving average: Smoothed MA (SMMA) instead of Simple MA (SMA), confirmed by "Trading Chaos" book. Thanks beckerben.

No breaking changes this time. Just wanted to thank Andrew (avishn) for his contribution to the library.

Summary of changes in 2010.11:

* Added: Kendall Tau Rank correlation (courtesy avishn)

P.S. Unfortunately, a brand spanking new trend indicator by David Varadi, MSR, didn't make it to the release. Nevertheless, here's it coded in Wealth-Lab.NET for those early adopters:

New trend indicator: MSR by David Varadi

New version is out - 2011.02. Summary of changes:

From the TrendStrength family of indicators by Jose Cruset, added four:

* Added: TrendStrengthA
* Added: TrendStrengthB
* Added: TrendStrengthC
* Added: TrendStrengthD

What's new in Community Indicators library v.2011.03:

* Added: KVO (Klinger Volume Oscillator)

No highlights in Community Indicators version 2011.04.

* Added: SMA2 (Simple moving average). Uses a different algorithm. Courtesy chamoun.

According to its author, this implementation is not as effective computationally as the Wealth-Lab version but is designed to better handle some special scenario:

QUOTE:
"...if an algorithm is using categorical variables relying on if X >,=,< Y type decisions than the differences become very problematic when your data series has zeros interspersed among large non zero #s. (...) The issue is not restricted to MoneyFlow but any series derived from the product of any two double numbers divided by a third number."

New version is out - 2011.09.

Change summary:

* Added: Skewness requested by Christos
* Added: Kurtosis
* Change: possible to install in Wealth-Lab 6.2+
* Fixed: Broken Wiki link for Beta online manual

What's new in Community Indicators library 2012.02:

* New: WLMA (Wealth-Lab Moving Average)
* New: Adaptive Lookback - fast swing version
* New: Bollinger BandWidth (requested by Ruschem)
* New: Bollinger %b (requested by Ruschem)
* Fix: Broken Wiki links for Correlation/CorrelationXL online manuals (thanks thodder)

Eugene:
It seems that the latest incarnation of the Adaptive Lookback is labeled "fast swing version". Is this because there is an older version that captures longer periods? The calculation for this "fast swing" version is turning out too short periods for me (at least half of what I would calculate manually).

The newly added 'fastSwing' version does not replace the old version. The calculation (which wasn't documented) is simply: take 2 bars before the swing bar and always 1 after (the default formula takes 2 bars on both sides).

The change was not breaking and does not affect existing code in any way. You can only use it by explicitly calling that overloaded call in your Strategy.

Got it. Thanks.

Let's have this 'blog' thread do what it's been doing for a decade now i.e. announcements. If the fact that the link for a handful indicators (like KST) points to an external site is a concern, you're welcome to discuss KST in this thread:
