Opening prices

[BerkoBob]

Hello again,

I need the opening price at the beginning of each day, week and month.

For the day and month I use:

if (day() != day(-1)) mvVar = open();

if (month() != month(-1)) myVar = open();

As there is no week() function that I know of I'm struggling to identify the beginning of the week i.e. Monday.

So far, I've got this:

var today = new Date();
if (today.getDay() == 1) myVar = open();

but it isn't working. When I use bar replay today.getDay() is always 5 because today (the day I'm actually doing this rather than the day of the bar I'm looking at) is Friday.

I hope this makes some sense to someone who can help me.

I just need the opening price on a Monday morning.

Thank you in advance.

Hi Bob,
this could be an idea.

var today = new Date();
function main() {
debugPrintln(today.getDay());
debugPrintln(open(-today.getDay()+1,inv("D")));
debugPrintln(open(-today.getDay()+1-today.getDay(),inv("D")));
debugPrintln(open(-today.getDay()+1-2*today.getDay(),inv("D")));
// and so on ... or you can use a loop
}

What do you think of this:

if (open(inv("W")) != open(inv("W")).getValue(-1))
myVar = open(inv("W"));

I'm assuming that no week will have the same opening price as its previous week.

It seems to work.

Bob, good idea.
Open(inv("W") make it easier.

I would do this way:

var myVar=null;
function main() {
if (open(0,inv("W")) != myVar) {
myVar = open(0,inv("W"));
debugPrintln(myVar);
}
}

If you want to be sure 99,99%, for weeks with the same opening price you could add a check on the close(inv("W")).
