User control with Edit Studies

[jethro87]

With the Edit Studies function on an advanced chart, I would like to control the -
Line (Bar) thickness
Line (Bar) color
Line (Bar) style
and placing the line (bar) at a user defined value.

I have an efs example of user defined control of the Thickness and Color. I tried to search the boards for examples of style and value placement. I know I am using the wrong search criteria because I can not find what I want.

I have the thickness, color, style and placement hard coded in my efs but I would like to make the efs more user friendly.

Thank you.

Try the following example which will allow you to draw a line at a specified price level (no line is drawn if price is not specified) and modify its pen style between _DOT and _SOLID
Alex

function preMain(){
    setPriceStudy(true);
    
    var fp1 = new FunctionParameter("Price", FunctionParameter.NUMBER);
    fp1.setDefault(); 
        
    var fp2 = new FunctionParameter("LineStyle", FunctionParameter.STRING);
    fp2.addOption("PS_DOT");
    fp2.addOption("PS_SOLID");
    fp2.setDefault("PS_SOLID"); 
}

function main(Price,LineStyle){

    if(Price!=null)
    drawLineRelative(-100,Price,100,Price,eval(LineStyle),2,Color.red,"line");

    return;
}

Adding Text to Line

How can I add drawTextAbsolute to a code similar to Alexis put up here. I would like to add the text next to the line.

I would like to input the price level to draw the line and also have the text next to it to show what that level is. I removed the LineStyle input.

I tried the following right after the drawline and I get an error that Price is not defined.

Appreciate any help. Thanks in advance

    drawLineRelative(-100,Price,100,Price,PS_SOLID,2,Color.red,"Line");
drawTextAbsolute(2, Price.getValue(), "Price=" +Price.getValue(), Color.cyan, null, 
                 Text.FRAME | Text.VCENTER | Text.BOLD, "Arial", 12, "Price");

The error message is generated because Price is not a series from which you can retrieve a value using the .getValue() method but is a single value defined with a functionParameter. In the drawTextAbsolute() command replace both instances of Price.getValue() with Price and it will work correctly

Draw Lines only from start of Today

Is there a way to just draw the line from start of day session to the present bar only.

I tried using the return array function but it draws a line going back left all the way. I would just like to have the line start at 9:30 or the start of day session of the contract. Thanks again for any suggestions.

AK

return new Array (dOpen,dHigh,dLow,dClose,Price);

Thanks Alexis

Alexis I figured it out using getFirstBarIndexofDay.

Thanks for your help here and in other posts.
