5 min high & low every min in a 5 min study

[windswepttom]

I want to know the High & Low over the past 5 min every min in a real time 5 min study. To put it another way, I want to do a 5 min study every min.

I was thinking of using an array of 5 for the high & low and every min push the high & low for the last min on it. Then loop thorugh it to find the high & low over the last 5 min every min.

I also thought I could use a series somehow to do this. I found information on the different functions in a series but no real doc on putting it all together or any examples of what I want to do. I know it is their someplace, but I could not find it. Can someone point me to it?

I also saw something on having multiple time studies in one study. Maybe could do a 1 min study and reference the last 5 bars with in the 5 min study?

Any thoughts on the best way to do this?

Thanks

Assuming I understood correctly what you are trying to accomplish which is to calculate the 5 minute High and Low while plotting a 1 minute chart then there are several ways you can do that.
The simplest one is to use the inv() function which allows you to base a price series or study on an interval that is different from the one being charted (see the link for the required syntax)
Enclosed below is a very basic example of a script that will return the 5 minute High and Low using the inv() function. A fully adjustable version of this script is available in this post.

function preMain(){
    setPriceStudy(true);
    setDefaultBarFgColor(Color.blue,0);
    setDefaultBarFgColor(Color.red,1);
    setCursorLabelName("High",0);
    setCursorLabelName("Low",1);
}

function main(){

    var xHigh = high(inv(5));
    var xLow  = low(inv(5));
    
    return new Array (xHigh,xLow);
}

Thanks Alexis for your input, but
I want to plot a 5 min chart and in real time and I want to get the high & low for the last 5 min every min. So say I have a 5 min chart that printed a new bar at 10:05. Then at 10:06 I want to know the high and low between 10:01 and 10:06 and then at 10:07 I want the high and low between 10:02 and 10:07 and so on.

If you want to retrieve the High and Low of a specific bar of a lower interval then create a price series based on that interval eg
var xHigh = high(inv(1));
var xLow = low(inv(1));
at which point you can retrieve the values of the individual 1 minute bars by using the getValue() method and specifying a bar index eg
var nHigh_1 = xHigh.getValue(-1);//High of the prior 1 minute
var nLow_2 = xLow.getValue(-2);//Low of 2 bars ago of the 1 min chart
If instead you want to calculate the highest and lowest values based on the last five 1 minute bars then replace
var xHigh = high(inv(1));
var xLow = low(inv(1));
with
var xHigh = upperDonchian(5,inv(1));
var xLow = lowerDonchian(5,inv(1));
and return the following to the chart
return new Array (xHigh.getValue(0), xLow.getValue(0));
Note that on historical bars the plots will obviously match the High and Low of the 5 minute bars but on the current bar you will get the highest and lowest values of the High and Low based on the last five 1 minute bars.
Enclosed below is a basic script that uses the latter example
Alex

function preMain(){
    setPriceStudy(true);
    setPlotType(PLOTTYPE_SQUAREWAVE,0);
    setPlotType(PLOTTYPE_SQUAREWAVE,1);
    setDefaultBarFgColor(Color.blue,0);
    setDefaultBarFgColor(Color.red,1);
    setCursorLabelName("High",0);
    setCursorLabelName("Low",1);
}

var xHigh = null;
var xLow  = null;

function main(){

    if(xHigh==null) xHigh = upperDonchian(5,inv(1));
    if(xLow==null)  xLow  = lowerDonchian(5,inv(1));

    return new Array (xHigh.getValue(0), xLow.getValue(0));
}

Alexis, Thank you very much.
Just what I was looking for.
