Can't display Highest High

[perrydolia]

I am having difficulty displaying the highest high for the year. I believe I am not using the highest() function properly.

How can I get a line on the chart to display the highest high?

Thanks for any help.

Here is the failing code:

var seriesHH=0;

function preMain() {

setStudyTitle("MMD252dH&L");
setCursorLabelName("MMD252dH&L",0);

setDefaultBarFgColor(Color.black,0);

setPriceStudy(true);
}

function main() {

seriesHH=highest(252,high());
return(seriesHH());
}

Try This..

var seriesHH=0;

function preMain() {

setStudyTitle("MMD252dH&L");
setCursorLabelName("MMD252dH&L",0);

setDefaultBarFgColor(Color.black,0);

setPriceStudy(true);
}

function main() {

seriesHH=highest(252,high()); 
return seriesHH;
} 

You don't want to return "seriesHH()" because that FUNCTION does not exist. You want to return the VARIABLE NAME that contains the Highest High value.

Brad,

Thank you for your reply.

I copied and pasted your code into my EFS study, checked, saved and reloaded, but I still don't see any lines on my chart.

Does it work for you?

And, when I insert

debugPrintln(seriesHH);

it just returns

[object Series]

Why does it not return a number?

Object Series values are not simple numbers. They are (normally) an array (or series of numbers).

Try using ...

debugPrintln(seriesHH.getValue(0));

and see if you get a valid number.

Thank you for your continuing help.

Here are the two line of code in Main

seriesHH=highest(252,high());
debugPrintln(seriesHH.getValue(0));

now the Formula Output window returns

null

on every line

so there is no value in seriesHH?

OK, I fixed it

I didn't have 252 days of data on the chart, so it couldn't display the highest high in 252 days.

I put 1000 bars on the chart and the line shows fine.

Thank you for all the help.

looks like you might have run into a limit with the number of bars you are trying to calculate with this function. If I change the value to 2 or 5, it works fine. Running it with your default value appears to result in a null return.

You might have to try to write your own lookup function to handle this.

var vHH=0;

function preMain() {

setStudyTitle("MMD252dH&L");
setCursorLabelName("MMD252dH&L",0);

setDefaultBarFgColor(Color.black,0);

setPriceStudy(true);
}

function main() {

vHH = highest(52,high()); 
debugPrintln(vHH.getValue(0));

return vHH.getValue(0);
}
