Help With Plotting Only Todays Open Info, Please

[Diane P]

Good Morning,
I'm trying to plot the prices from open downward & from open upward for current day only.However, the previous days show up as well. Is there some way I can show only current day open? Thank you.

Here is what you need to do.
Create a global variable [ie outside of preMain() and main()] called bCurrentDay and set it initially to false eg

var bCurrentDay = false;//copy this line

function main(){//do not copy this line. It is here only as a reference

//rest of your code 

Then at beginning of main() insert the code enclosed below. This will make your script plot/draw only today's line/values .
Alex

function main(){//do not copy this line. It is here only as a reference
//copy the following code block
    if(getBarState()==BARSTATE_ALLBARS){
        bCurrentDay=false;
    }
    if (bCurrentDay == false && getDay(0) != getDay(-1)){ 
        var xTime = getValue("time");
        var xDate = new Date(); 
        var sTime = (xTime.getMonth()+1+"/"+xTime.getDate()+"/"+xTime.getFullYear()); 
        var sToday = (xDate.getMonth()+1+"/"+xDate.getDate()+"/"+xDate.getFullYear()); 
        if ( sTime == sToday ) { 
            bCurrentDay = true; 
        } 
    } 
    if (bCurrentDay==false){
        return;
    }  

    //rest of your code

In addition to what I suggested in my previous message you could also simplify your script as follows.
In this section of code

var vTime=getValue("Time");
var OpenD = open(inv("D"));
var vFirstIndex = getFirstBarIndexOfDay(vTime,getSymbol()+",D");
if(vFirstIndex!=null && getDay(0)!=getDay(-1)){  
    debugPrintln(getCurrentBarIndex()+" "+vFirstIndex);
    vTodaysOpen=getValueAbsolute("open",vFirstIndex,getSymbol()+",D");
} 

delete all the lines except var OpenD = open(inv("D"));
Then in what will remain of your original script replace each instance of vTodaysOpen with OpenD.getValue(0)
