Fisher Transform

The attached efs is a variation of the Fisher.efs posted earlier in this thread and is configured to compute the indicator using any one of the studies listed in the Study parameter that can be accessed through Edit Studies (more could be added if required). To change the parameters for any one of the studies just type the new parameters in place of the existing ones.
The efs is also enabled for use with multiple intervals and/or external symbols
eSignal version 7.9 is required to run this efs.

amStudies library revision 5

A new version of the amStudies Library is now available here. Also in the same folder are the documentation (in HTML format) and the amStudies.xml file (which allows the studies to be listed in the Editor's Toolbox). For more information on the amStudies Library see this post.
The new function added to this revision is the KST (Know Sure Thing). This indicator was developed by Martin Pring and described in the "Summed Rate Of Change (KST)" article published in the September 92 issue of TAS&C. Please refer to that article and to the amStudies documentation for an explanation of the required parameters.
eSignal version 7.9.1 build 732 or later is required to use the amStudies Library.

KST (Know Sure Thing)

The attached efs uses the amKST() function included in the amStudies library to plot Martin Pring's KST (Know Sure Thing) indicator and is enabled for use with multiple intervals and external symbols..
The parameters for the KST include the period(s) used for the calculation (see quote box below for an explanation), the type of average used ie simple (the default) or exponential, the source (default is Close) and the symbol and/or Interval used.
eSignal version 7.9.1 build 732 or later is required to run the efs.
Copy [or updated version] of the efs is also available here
Alex

The Period parameter of the amKST() function must be one of the following:

• a string containing the periods of each roc and ma study ORd together in the following sequence
"roc1|ma1|roc2|ma2|roc3|ma3|roc4|ma4"
for example "10|10|15|10|20|10|30|15"

• any one of the following strings
"ShortD", "ShortW", "IntermediateW", "LongM", "LongW"
These strings correspond to preset combinations of periods as suggested by Pring in his article "Summed Rate Of Change (KST)" published in the September 92 issue of TAS&C (they also use the same naming convention)

So the period parameter could be written in either one of the following ways and in the case of this example would return the same exact plot (see enclosed image)
amKST("ShortW", false)
or
amKST("3|3|4|4|6|6|10|8", false)



In the attached efs all the preset combinations can be selected through Edit Studies. The efs also offers an additional option (which is marked as Insert parameters here) in which the individual settings can be input manually (see following image). Note that when you insert the parameters manually in Edit Studies you must not enclose them in quotes"".



If you would like to create some additional ready made combinations that can be selected through Edit Studies just insert them as addOption() statements in the Function Parameter (see following image)



Once you have done that these custom options will become available in Edit Studies (see following image)

KST with Moving Average

The attached efs uses the amKST() function to compute the KST indicator and its moving average (see also prior message). The study is enabled for use with multiple intervals and/or external symbols.
eSignal version 7.9.1 and the amStudies.efsLib library are required to run this efs. For more information on the amStudies library see this post.

Parabolic SAR

The attached efs replicates the Parabolic indicator found in TradeStation 2000i and is enabled for use with multiple intervals.
eSignal version 7.9.1 or later and the Parabolic.efsLib function library are required to run this efs. The Parabolic.efsLib function library can be found here together with its documentation.
Copy [or updated version] of the efs is also available here
Alex

Note1: Compared to the equivalent TradeStation function the Parabolic function used by this efs has an additional user defined parameter which is used to set the maximum acceleration factor.
Note2: As with the TradeStation 2000i Parabolic indicator this efs displaces forward by one bar the value calculated by the Parabolic function which means that it will reverse only once a bar is completed. To have the indicator reverse in real time on the current bar see the notes contained at the end of the script.

Parabolic Oscillator

The attached efs computes the Parabolic Oscillator and is enabled for use with multiple intervals. The oscillator represents the difference between the Close and the Parabolic indicator value.
eSignal version 7.9.1 or later and the Parabolic.efsLib function library are required to run this efs.

amFunctions library revision 4

A new version of the amFunctions Library is now available here. Also contained at the same location is the documentation in HTML format. For more information on the amFunctions Library see this post.
The new function added to this revision is the Median. This function sorts the series that is being passed to it and returns the median for the specified period. If the period is an odd number (eg 3, 5, 7, etc) it uses the middle value while if it is an even number (eg 4, 6, 8, etc) it finds the two innermost values and averages them. Enclosed below is a basic code example showing how to use the function to calculate the Median of the Close over 7 periods. The function can be used with any eSignal or custom series and can be computed on external intervals and/or symbols
eSignal version 7.9.1 build 732 or later is required to use the amFunctions Library.
Alex

function preMain(){
    setPriceStudy(true);
    setCursorLabelName("Median");
}

var amLib = addLibrary("amFunctions.efsLib");//call the library
var xMedian = null;//declare the variable

function main(){
    if(xMedian==null) xMedian = amLib.amMedian(7,close());//initialize the function
    return xMedian.getValue(0);//return the value
}

The attached efs computes the Momentum Divergence indicator developed by Price Headley and is enabled for use with multiple intervals and/or external symbols.
