Calculating the High from a MA Study

[jnorton]

I would like to calculate the delta on a bar daly bar chart.The calculation should be the distance from todays high to a given line. For testing the system I will use the 10 day moving average line. Any ideas?

[Doji3333]

Here is some help..

First...

open an EFS EDITOR window (TOOLS, EFS, EDITOR), then click on the OPEN FORMULA button...

Now, open the BuiltinMA.efs (located in the BUILTIN folder). This is a basic Moving Average formula. It will look like this..

var vMA = null;

function preMain() {
    setPriceStudy(true);
    setStudyTitle("MA");
    setCursorLabelName("MA", 0);
    setDefaultBarFgColor(Color.blue, 0);
    setDefaultBarThickness(1,0);
        
    var fp1 = new FunctionParameter("Length", FunctionParameter.NUMBER);
    fp1.setLowerLimit(1);        
    fp1.setDefault(10); //Edit this value to set a new default
    
    var fp2 = new FunctionParameter("Offset", FunctionParameter.NUMBER);
    fp2.setDefault(0); //Edit this value to set a new default
    
    var fp3 = new FunctionParameter("Source", FunctionParameter.STRING);
    fp3.setName("Source");
    fp3.addOption("Close");
    fp3.addOption("High");
    fp3.addOption("Low");
    fp3.addOption("Open");
    fp3.addOption("HL/2");
    fp3.addOption("HLC/3");
    fp3.addOption("OHLC/4");
    fp3.setDefault("Close"); //Edit this value to set a new default    
    
    var fp4 = new FunctionParameter("Type", FunctionParameter.STRING);
    fp4.setName("Type");
    fp4.addOption("MAStudy.SIMPLE");
    fp4.addOption("MAStudy.EXPONENTIAL");
    fp4.addOption("MAStudy.WEIGHTED");
    fp4.addOption("MAStudy.VOLUMEWEIGHTED");
    fp4.setDefault("MAStudy.SIMPLE"); //Edit this value    to set a new default

}

function main(Length,Offset,Source,Type) {
   
    if (vMA == null) vMA = new MAStudy(Length, Offset, Source, eval(Type));
 
/*****************************************

******************************************/

    
    return vMA.getValue(MAStudy.MA);
} 

Now, comparing the recent high to the MA value is as simple as adding one line.

var HighfromMA = high()-vMA.getValue(MAStudy.MA); 

you would add it here (for most uses).

var HighfromMA = high()-vMA.getValue(MAStudy.MA);

    
    return vMA.getValue(MAStudy.MA);
} 

Now, if you wanted to SUM the values for multiple bars, you would have to create a function (the most logical way to handle this...

function GetMAHighValue(length) {
var x;
var MAHighSum = 0;

   for(x=0;x<(length-1);x++) {
     MAHighSum += high(-x)-vMA.getValue(MAStudy.MA,-x);
   }
 return MAHighSum;
} 

You would use this function as shown here..
