Applying a window to the filter weights provides sometimes extra control over the characteristics of the filter.In this script an hamming window is applied to the volume before being used as a weight.In general this process smooth the frequency response of a filter. Lets compare the classic vwma with hamming windowed vwma Something i noticed is that windowed...
It passes the Rate of Change data through a Butterworth filter which creates a smooth line that can allow for easier detection of slope changes in the data over various periods of times. The butterworth filter line and the rate of change are plotted together by default. The values for the lengths, for both the butterworth filter and the raw ROC data, can be...
When i was in Japan with some traders colleagues we talked about traditional charting tools from this country and how they changed the way we look at our charts today. Then suddenly one of the japanese traders i have met earlier said "Why not making another charting tool ? Smoother than Heikin-Ashi and including all the information a trader may need but easier to...
Single Exponential Smoothing ( ema ) does not excel in following the data when there is a trend. This situation can be improved by the introduction of a second equation with a second constant gamma . The gamma constant cant be lower than 0 and cant be greater than 1, higher values of gamma create less lag while preserving smoothness.Higher values of length ...
Finite Impulse Response (FIR) Filter indicator script. This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 20:7 (26-31): Zero-Lag Data Smoothers). NOTE: Ehlers' favorite FIR filter had 1, 2, 3, 3, 2, 1, 0 coefficients.
Recursive Median Filter indicator script. This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 36:03 (8–11): Recursive Median Filters).
Vertical Horizontal Filter was initiated by Adam White. It was first published in a magazine called “Issues of Futures” in August, 1991. The Vertical Horizontal Filter (VHF) is a very common Indicator used by traders to find out the Phase of a Price Trend. Normally, a price trend can be in a Trending Phase or a Congestion Phase/Choppy Movement Phase. Adam...

Gives you an average of which side of the EMA price has close without the noise of the chart. Useful for measuring trend strength or as a trade filter (eg. only go long if above / below)
Rocket RSI indicator script. This indicator was originally developed by John Ehlers (Stocks & Commodities V.36:6, RocketRSI - A Solid Propellant For Your Rocket Science Trading).
Infinite Impulse Response (IIR) Filter indicator script. This indicator was originally developed by John Ehlers (Stocks & Commodities V. 20:7 (26-31): Zero-Lag Data Smoothers).
A least squares filter using the Auto line as source, practical for noise removal without higher phase shift. Its possible to create another parameter for the auto-line length, just add a parameter Period or whatever you want. r = round(close/round)*round dev = stdev(close,Period) Hope you enjoy :)
An indicator inspired by the Renko chart.Instead of using a static box size we use standard deviation, this make the indicator more reactive to the market state. If the indicator show no values then you have to round the price to the nearest integer, for that use the round parameter. Hope you enjoy :)
This study is an experiment utilizing the Ehlers Gaussian Filter technique combined with lag reduction techniques and true range to analyze trend activity. Gaussian filters, as Ehlers explains it, are simply exponential moving averages applied multiple times. First, beta and alpha are calculated based on the sampling period and number of poles specified. The...

Laguerre Filter indicator based on the John Ehler's article "Time Warp – Without Space Travel" about the Laguerre Transform

This is an experimental study designed to identify underlying price activity using a series of Laguerre Filters. Two different modes are included within this script: -Ribbon Mode - A ribbon of 18 Laguerre Filters with separate Gamma values is calculated. -Band Mode - An average of the 18 filters generates the basis line. Then, Golden Mean ATR over the specified...
