Import: SI - Horizontal Line at X

[JayF]

.

Simple idea for Esignal
(1)Metastock allows you type in "number" for horizontal line.
(2)Esignal requires you to place horizontal line using
"mouse"
(3)Support and Resistance lines are important in trading.
(4)Hope Esignal catches up with Metastock stock and allow
you to insert "number" just like it allows you to insert
a color.

Larry,

Here's a simple EFS that allows you to draw a horizontal line at a set price.

Project Description:  

This formula will place a horizontal line at a given price level.
Please note that the price level must be defined in the Edit Studies window
before any lines are drawn.  If multiple lines are needed, please create
another instance of the formula.

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


function preMain() {
    setPriceStudy(true);
    setStudyTitle("Horizontal Line at X");
    setShowCursorLabel(false); 
    
    var fp1 = new FunctionParameter("PriceLevel", FunctionParameter.NUMBER);
    
    var fp2 = new FunctionParameter("Color", FunctionParameter.COLOR);
    fp2.setDefault(Color.black);
    
    var fp3 = new FunctionParameter("Thickness", FunctionParameter.NUMBER);
    fp3.setDefault(1);


}

function main(PriceLevel,Color,Thickness) {

if (PriceLevel == null) return;

addBand(PriceLevel,PS_SOLID,Thickness,Color," ");

return;
}

What can I do if I have setPriceStudy(false)?

David,

That will create a separate non-price study window with a line at X, but without anything returned in the window it won't have a scale. Since there is no scale, nothing will be displayed (unless overlayed on top of another study.)

I knew I wasn't clear, sorry.

Let's say I have an efs that plots some indicator in the lower pane.

This efs also calculates where I want to draw my line on the price chart.

Can I add something to the efs to draw the line in the price chart area?

[JayF]

David,

Unfortunately, no. With the exception of coloring price bars, a non-price study cannot do anything in the price area.
