barDate = getValue("time"); how to use it for Day Of Week table

[fastflyer]

I like to use a very small chart to display a very small table of data. I use the time frame of 390 minutes since this works well for the Dow futures to get the Hi Low Range during regular market hours, 09:30 to 16:00. I simply display the change from the previous close and the range ... and I like the day of week to be shown too ( M T W Th F ).

I have worked with


barDate = getValue("time");
dayOfWeek = barDate.getDay();

that I had found in another post. No suprise here, I have not been able to get it to do what I want.

Instead of having to update this part of the code each day, manually incrementing the T to W , M to T, and so on

if(getBarState()==BARSTATE_NEWBAR) {


drawTextRelative( x1, y1, " T" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 112);
drawTextRelative( x1, y2, " M" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 113);
drawTextRelative( x1, y3, " F" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 114);
drawTextRelative( x1, y4, " Th" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 115);
drawTextRelative( x1, y5, " W" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 116);
drawTextRelative( x1, y6, " T" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 117);
drawTextRelative( x1, y7, " M" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 118);
drawTextRelative( x1, y8, " F" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 119);
drawTextRelative( x1, y9, " Th" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 120);
drawTextRelative( x1, y10," W" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 121);
drawTextRelative( x1, y11," T" , Color.yellow,null,Text.BOLD|Text.VCENTER|Text.RELA TIVETOTOP|Text.RELATIVETOLEFT, "Courier New", 12, 122);
}

Is there a way that some one who is adept at coding ( not me : ) would have the program do this automatically ?

Thanks,
Glenn

Hello Glenn,

One approach would be to use the following

function main()
{

    // getValue("time") --> Fri Nov 25 2016 13:00:00 GMT+1100 (AUS Eastern Daylight Time)
    //                      0123456789012345678901234567890123456789012345678901234567890
    //                                1         2         3         4         5         6


    var FullDateTime = "" + getValue("time")
    var thisTime = FullDateTime.substr(16,5);
    var thisDateTime = FullDateTime.substr(0,21);
    var thisDay = FullDateTime.substr(0,3);

    var thisBI = getCurrentBarIndex()
    var intBI = parseInt(thisBI);

    if(intBI == 0)
    {
        debugPrintln("thisDay: " + thisDay + "\tthisDateTime: " + thisDateTime);

        switch(thisDay)
            {
                case "Mon":

                    debugPrintln("Day = MONDAY");

                    break;

                case "Tue":

                    debugPrintln("Day = TUESDAY");

                    break;
                case "Wed":

                    debugPrintln("Day = WEDNESDAY");

                    break;
                case "Thu":

                    debugPrintln("Day = THURSDAY");

                    break;
                case "Fri":

                    debugPrintln("Day = FRIDAY");

                    break;

                default:

                    debugPrintln("Day = either SATURDAY or SUNDAY");

            }
    }          

    return null;
} 

I tried using if(getBarState() == BARSTATE_ALLBARS) but this acts on the last bar in the chart (i.e. the earliest bar)
BARSTATE_CURRENTBAR and BARSTATE_NEWBAR did not seem to work, hence the reason I used the BarIndex.
