Changing the filename

[sunman4008]

Hello,

How do I change the file name in the code instead of the variable declaration?

Here is my code:
var f = new File( "newsymbol.txt" );
var counter = 0;
var newDateObject = new Date(year, month, day);

function main()
{
var nNumberBars;
var nBarIndex = getCurrentBarIndex();
var nBarState = getBarState();

nNumberBars = getNumBars();



if ((nBarIndex==0) && (nNumberBars != 0) )
{
f = sym + ".txt";
f.open( "wt" );
counter = 0;
while (counter != nNumberBars)
{
// debugPrintln("open2=",newDateObject);
f.writeln(getYear(counter)+ "/" + getMonth(counter) + "/" + getDay(counter)+","+open(counter).toFixed(4) +",",high(counter).toFixed(4)+","+low(counter).toF ixed(4)+","+close(counter).toFixed(4));
counter = counter - 1;
}
}
f.close;
return(0);

Hi,

I didn't test it but this should work:

var f;
 var counter = 0;
 var newDateObject = new Date(year, month, day);

 function main() 
 {
 var nNumberBars;
 var nBarIndex = getCurrentBarIndex(); 
 var nBarState = getBarState(); 

 nNumberBars = getNumBars();



 if ((nBarIndex==0) && (nNumberBars != 0) )
 {
 f = new File( sym + ".txt" );
 f.open( "wt" ); 
 counter = 0; 
 while (counter != nNumberBars)
 {
 // debugPrintln("open2=",newDateObject);
 f.writeln(getYear(counter)+ "/" + getMonth(counter) + "/" + getDay(counter)+","+open(counter).toFixed(4) +",",high(counter).toFixed(4)+","+low(counter).toF ixed(4)+","+close(counter).toFixed(4));
 counter = counter - 1;
 } 
 } 
 f.close;
 return(0);

Says f is undefined

Thus the need for testing. Since I didn't change the original script other than code specific to your question: creating the file object, the syntax error +",", wasn't addressed and the variable "sym" was never defined, one of your ...toFixed(... had a space as in: ...toF ixed(..., and last corrected the newDateObject equality functions. See http://kb.esignalcentral.com/article...ticle=1206&p=4 and KB for explanation and syntax for these functions.

var counter = 0;

function main() {
    var f;
    var newDateObject = new Date(year(0), month(0), day(0));
    var nNumberBars;
    var nBarIndex = getCurrentBarIndex();
    var nBarState = getBarState();

    nNumberBars = getNumBars();



    if ((nBarIndex == 0) && (nNumberBars != 0)) {
        f = new File(getSymbol() + ".txt");
        if(!f.isOpen()) f.open("wt");
        counter = 0;
        while (counter != nNumberBars) {
            //debugPrintln("open2= ",newDateObject);
            f.writeln(getYear(counter) + "/" + getMonth(counter) + "/" + getDay(counter) + "," + open(counter).toFixed(4) + "," + high(counter).toFixed(4) + "," + low(counter).toFixed(4) + "," + close(counter).toFixed(4));
            counter = counter - 1;
        }
        f.close;
    }
     return (0);
}

FWIW: to avoid the while loop from executing on every tick I added a flag to allow only one iteration of the if... while... loop and since (I assume) it should only run on a daily interval I added an interval check.

var counter = 0;
var bInit=false;;
var stopFlag=0;//added to stop execution once the file is created
function main() {
    if (!isDaily()) {//code from http://forum.esignal.com/showthread.php?38596-Working-with-Futures-Volume-data
        if(!bInit) {//added since it requires a daily interval
            addEntitlement("DailyValues", "This study requires a dialy interval");
            bInit = true;
        }
        return;
    }
    var f;
    var newDateObject = new Date(year(0), month(0), day(0));
    var nNumberBars;
    var nBarIndex = getCurrentBarIndex();
    var nBarState = getBarState();
    nNumberBars = getNumBars();

    if (nBarIndex == 0 && nNumberBars != 0 && stopFlag != 1) {
        f = new File(getSymbol() + ".txt");
        if(!f.isOpen()) f.open("wt");
        counter = 0;
        while (counter != -nNumberBars) {
            //debugPrintln("open2= ",newDateObject);
            f.writeln(getYear(counter) + "/" + getMonth(counter) + "/" + getDay(counter) + "," + open(counter).toFixed(4) + "," + high(counter).toFixed(4) + "," + low(counter).toFixed(4) + "," + close(counter).toFixed(4));
            counter = counter - 1;
        }
        f.close();
        stopFlag=1;
    }
    return (0);
}
