This is an improved version of the momentum indicator.
The n-period momentum is the difference between the close of the last bar and the close n bars ago. When a large bar n periods ago drops out of the momentum calculation, this can create a significant distortion, as it will show as a change in momentum, even if there was no or little price change for the last bar.
To eliminate this problem, the input value n bars ago was replaced with the triangular moving average SMA(SMA(Input, n+1), n+1)[0]. This modification does not change the usability of the momentum indicator, but simply eliminates the distortion.
These are the 2 pole and 3 pole Butterworth Filters, which were described by John F. Ehlers in his book "Cybernetic Analysis for Stocks and Futures". Ported from Easy Language to NinjaTrader.
The chart shows that the 2 pole filter (red) gives a better approximation for price, while the 3 pole filter (blue) offers superior smoothing.
The Double Exponential Moving Average (DEMA) was first presented by Patrick Mulloy in "Stocks & Commodities" in 1994. It attempts to offer a smoothed average with less lag than a straight exponential moving average.
The Double Weighted Moving Average (DWMA) replicates the DEMA formula, applying it to the WMA (weighted moving average) instead of the EMA.
The Hull Moving Average (HMA) was developed by Alan Hull and is mainly used to identify the current market trend. The HMA is composed of three weighted moving averages (WMA).
The Exponential Hull Moving Average (EHMA) has those weighted moving averages replaced with exponential moving averages.
The Exponential Hull Moving Average exhibits an excellent balance between smoothing and lag (also see "Moving Averages for Financial Data Smoothing" by Aistys Raudys, Edmundas Malčius, and Vaidotas Lenčiauskas – Vilnius University, Faculty of Mathematics and Informatics)
This is Gaussian Filter, as described by John F. Ehlers in his publication "Gaussian and other Low Lag Filters". The number of poles can be selected between 1 and 4.
The chart shows that the 1 pole filter (yellow) gives a better approximation for price, while the 4 pole filter (blue) offers superior smoothing.
Update October 1, 2012: Small bug removed. Indicator will now correctly display when a period of 1 is selected.
You may set the number of poles in the filter to 1,2,3 or 4. A 1-pole filter will have a better approximation to price, whereas the 4-pole filter has superior smoothing.
To emulate the original Gaussian filter presented by John F. Ehlers, please select the PriceType "Median" as Input Series.
This is a generalized EMA, which allows you to use it with fractional periods. The minimum period required is 1.0.
This generalization is possible, as the integer period of an EMA is an artificial construct, which was adapted following the work of Jack K. Hutson, who compared simple and exponential moving averages. The generalized formula for an EMA is
EMA[0] = (1 - k) * EMA[1] + k * Price[0] , where 0 < k <= 1
The period n translates into k = 2/(n+1), so that n >= 1 is required not to violate the allowed range for k. Fractional values for n are possible.
The chart shows a fast EMA with a period of 12.7 and a slow EMA with a period of 38.3. The indicator which can be downloaded here, does not shade the region, a dual MA indicator will be released later.
The Holt EMA is a trend corrected exponential moving average based on a double exponential smoothing model.
Holt’s paper, “Forecasting Seasonals and Trends by Exponentially Weighted Moving Averages” was published in 1957 in O.N.R. Research Memorandum 52, Carnegie Institute of Technology.
The tools developed by Holt & Winters are mainly used for forecasting time series.
This is the same as the black version, with a change to the slow line to match the color of the cloud.
As in the black version "This is the default thinkorswim MovAvgTwoLines indicator modified. The two lines can now be different average types. Additional features include a cloud, vertical lines and arrows; all with on/off switches in the input parameters. Cloud color can be changed in the Globals option. For now the moving average types are the ones I use, EMA, SMA & WMA; might add more to the list later on."

December 27th, 2013 04:42 AM Maxie in welchem TF benutzt Du den Indi am Meisten? I can see the "alpha Auction bars"in the screen, sind die auch von Dir? Wü
rde ich gern ausproboieren, kannst Du mir sagen, wo ich die finde?
