EFS not opening

[J123]

I am also trying to ID NR7 bars, I tried changing the code below but for some reason it isn't opening, please see attached, do I need to make any further changes to get this to work?
I'm very grateful for any help.

On NR7, the following lines are suspect, I think 1 should be -1:

var this_hour = getHour(1);
var this_minute = getMinute(1); 

Regarding performance, ALL old bars are being tested 7 times when the study is first loaded, chart resized/refreshed, or symbol/interval changed. There are ways to reduce this, but it would make the code a lot more complicated.

I would make sure text is cleared out, as you might be taking a performance hit if it isn't (redrawing text multiple times). Add the following somewhere at the top of main():

if (nState == BARSTATE_ALLBARS) {
    clearText();
} 

Minor performance stuff:

Initializing a variable as a string that will be used as a number is probably a bad idea, as JavaScript may try treating it as a string first elsewhere in the code. I'd change the following to 0, -1, or null:

var widest_bar_index = "";
var narrowest_bar_index = ""; 

I'd try to get the symbol only once. There are several way to do this, one way is:

var symbol = null;
...
function main() {
    var nState = getBarState();
    if (nState == BARSTATE_ALLBARS) {
        symbol = getSymbol();
    }
    else if (nState == ... 

Once getHour(1) is changed to getHour(-1), you could just get it once, rather than inside 2 if statements.
