Multi Plot with LAST()

Optuma Scripting
1

Hi,
I have a simple script with multi plot and the function LAST() but have encountered unexpected results.

Here is the script:

//Count of all bars minus 1; 
$Bars = BARCOUNT(Month(PERIODAMOUNT = 1)) -1; 
//Std Dev of CAPE Detrended 
Var1 = (STD(BARS=$Bars)); 
Plot1 = Var1; 
Plot2 = Var1 * 2; 
Plot3 = Var1 * 3;

This script works as it should, here is the screenshot:
CAPE Detrended

Now I have changed the plot output to the last value using the LAST() function:

Here is the script:

//Count of all bars minus 1; 
$Bars = BARCOUNT(Month(PERIODAMOUNT = 1)) -1; 
//Std Dev of CAPE Detrended 
Var1 = (STD(BARS=$Bars)); 
Plot1 = LAST(Var1); 
Plot2 = LAST(Var1 * 2); 
Plot3 = LAST(Var1 * 3);

This script give some strange results, see the screenshot:
CAPE Detrended with LAST

What did I made wrong?

Thanks and best wishes,
Thomas

Hi,

Try the following alternate script:

//Count of all bars minus 1;
$Bars = BARCOUNT(Month(PERIODAMOUNT = 1)) -1;
//Std Dev of CAPE Detrended
Var1 = (STD(BARS=$Bars));
V2 = LAST(Var1) ;
Plot1 = V2 ;
Plot2 = V2 * 2 ;
Plot3 = V2 * 3;

Hi Matthew,

Hi Matthew,

sorry but I am here again. I have some issues with the formatting of the three lines.

Here is a loom video link:

As you can see I can change the setting of the lines but when I switch to another chart and than switch back to my “CAPE Detrended” chart all settings are gone.

What can I do so that all settings are permanent WITHOUT scripting the formatting settings? If the formatting can only be done permanently with scripting, what are the scripts.

Thanks,
Thomas

Hi,

Yes, you need to setup the lines in the script directly to keep them retained.

You can see examples here of how to do it:

type plot1. and you’ll see a list of available options you can select.
