problem with while loop

[futurenets]

the code below works fine if I exclude the if statement

if(barM >= 570 && barM < 960){

}

otherwise it doesn't complete. any ideas?

var sessionArray;
var ReqLength = 300;
function sessionData(){

    var sSI = getSymbol() + ",60"; 
    var index = 0;
    var barM = 0;
    var nLen = 0;
    var nClose = 0;
    var nRawtime = 0;
    var nHour = 0;
    var nMinute = 0;

    sessionArray = new Array();
    while(nLen < ReqLength){
        nClose = getValue("close", -index, 1, sSI)*1;
        nRawtime = getValue("rawtime", -index, 1, sSI)*1;
        nHour = getValue("hour", -index, 1, sSI)*1;
        nMinute = getValue("minute", -index, 1, sSI)*1;
        var tmp = new Object;
        tmp.Close = nClose;
        tmp.Rawtime = nRawtime;
        tmp.Hr = nHour;
        tmp.Mn = nMinute;
        barM = (tmp.Hr*60)+tmp.Mn;
        if(barM >= 570 && barM < 960){
            sessionArray.push(tmp);  
            ++aLen;
        }
        ++index;
    }   
}

also if I replace

if(barM >= 570 && barM < 960)

with

if(barM >= 570)

it completes ok.

var sessionArray;
var ReqLength = 300;
function sessionData(){

    var sSI = getSymbol() + ",60"; 
    var index = 0;
    var barM = 0;
    var nLen = 0;
    var nClose = 0;
    var nRawtime = 0;
    var nHour = 0;
    var nMinute = 0;

    sessionArray = new Array();
    while(nLen < ReqLength){
        nClose = getValue("close", -index, 1, sSI)*1;
        nRawtime = getValue("rawtime", -index, 1, sSI)*1;
        nHour = getValue("hour", -index, 1, sSI)*1;
        nMinute = getValue("minute", -index, 1, sSI)*1;
        var tmp = new Object;
        tmp.Close = nClose;
        tmp.Rawtime = nRawtime;
        tmp.Hr = nHour;
        tmp.Mn = nMinute;
        barM = (tmp.Hr*60)+tmp.Mn;
        if(barM >= 570 && barM < 960){
            sessionArray.push(tmp);  
            ++nLen;
        }
        ++index;
    }   
}

Hi futurenets,

Have you tried using debugPrintln and troubleshooting yourself? If yes, what did you see, if not, my recommendation is that you give that a shot.

yes thats how I found the problem. I'm pretty sure this is an internal eSignal efs problem.

[futurenets]

... the process ends prematurely without completing the script.

something isn't right here.

[futurenets]

can someone from eSignal please try this ...

1. run the following function.
2. replace "if(barM >= 570){" with "if(barM >= 570 && barM < 960){" and try again.

the process ends prematurely without completing the script.

var sessionArray;
var ReqLength = 300;
function sessionData(){

    var sSI = getSymbol() + ",60"; 
    var index = 0;
    var barM = 0;
    var nLen = 0;
    var nClose = 0;
    var nRawtime = 0;
    var nHour = 0;
    var nMinute = 0;

    sessionArray = new Array();
    while(nLen < ReqLength){
        nClose = getValue("close", -index, 1, sSI)*1;
        nRawtime = getValue("rawtime", -index, 1, sSI)*1;
        nHour = getValue("hour", -index, 1, sSI)*1;
        nMinute = getValue("minute", -index, 1, sSI)*1;
        var tmp = new Object;
        tmp.Close = nClose;
        tmp.Rawtime = nRawtime;
        tmp.Hr = nHour;
        tmp.Mn = nMinute;
        barM = (tmp.Hr*60)+tmp.Mn;
        //if(barM >= 570 && barM < 960){
        if(barM >= 570){
            sessionArray.push(tmp);  
            ++nLen;
            debugPrintln(sessionArray.length+","+nLen);
        }
        ++index;
    } 

}

Hi futurenets.

I do not believe this is a bug in eSignal. However, in deference to your request, I'll let someone from eSignal address your issue.

[futurenets]

ok thanks. something else ...

yesterday (May 14) this was working

var sSI = getSymbol() + ",60";
aClose = getValue("close", -300, 300, sSI);

today (May 15) it doesn't work but this does

var sSI = getSymbol() + ",60";
aClose = getValue("close", -299, 300, sSI);

Hi,

FWIW I ran the code with "if(barM >= 570 && barM < 960){" on a 1 minute ES #F chart on Saturday (market is closed) and it took a while but it printed to the Output Window correctly. Maybe during real time (and possibly if tested on Tick charts) eSignal is just having trouble keeping up with the real time calculations.

Here is the code I used:

var sessionArray;
var ReqLength = 300;
//function sessionData(){
function main(){
    var sSI = getSymbol() + ",60"; 
    var index = 0;
    var barM = 0;
    var nLen = 0;
    var nClose = 0;
    var nRawtime = 0;
    var nHour = 0;
    var nMinute = 0;

    sessionArray = new Array();
    while(nLen < ReqLength){
        nClose = getValue("close", -index, 1, sSI)*1;
        nRawtime = getValue("rawtime", -index, 1, sSI)*1;
        nHour = getValue("hour", -index, 1, sSI)*1;
        nMinute = getValue("minute", -index, 1, sSI)*1;
        var tmp = new Object;
        tmp.Close = nClose;
        tmp.Rawtime = nRawtime;
        tmp.Hr = nHour;
        tmp.Mn = nMinute;
        barM = (tmp.Hr*60)+tmp.Mn;
        debugPrintln("b - "+barM);
        if(barM >= 570 && barM < 960){
        //if(barM >= 570){
            debugPrintln("a - "+barM);
            sessionArray.push(tmp);  
            ++nLen;
            debugPrintln(sessionArray.length+","+nLen);
        }
        ++index;
    } 

} 

Ref:

aClose = getValue("close", -300, 300, sSI); 

Not sure but you might check that you had well over 300 bars loaded on the chart via the time template or via going backwards on the chart until you get enough bars loaded.

ok thanks Wayne. my orginal code is also working now?
