Weekly volume profile (POC) plotted forward on 30 minute chart

[daytrader023042]

Hi all,

Been struggling to wrap my head around why I can't get this script to work. It's a modified version of some code I found a while back on this forum by @SleepyZ (thank you!). I'm not a programmer, just some basic knowledge from this site and a little help from ChatGPT. Basically, I would like a script that works on a 30 minute chart and uses weekly volume profile to do the following... It should take each POC for the last three completed weeks, and then plot them beginning from their respective subsequent week (e.g. the POC for the week of Jan 5th should begin plotting on Jan 12th). The lines should continue to plot to the right indefinitely. At any one point, the study should only show the latest three POC plots. The lines should be magenta to begin, but once breached at any time after the week the line formed, it should become gray (indicating that price has visited the specific POC after the week it formed).

I've been able to get the script working on a daily chart using monthly volume profile, but after adjusting everything for the 30 minute chart, no luck. Nothing appears on the chart. I've checked chart settings, ensured the plot is enabled, etc...

Here is the working code for the daily chart, and a screenshot of what the end result looks like (working as expected). At the bottom of the post, I have included the code I have tried on a 30M chart using Weekly Volume Profile, with no luck. Any suggestions as to what I may be doing wrong here? Thanks in advance for any help.

    def currentMonth = HighestAll(monthID);
    def targetMonth  = currentMonth - daysback;

    def thisBarMonthID = monthID;

    def volp = reference VolumeProfile("time per profile" = "Month", "on expansion" = no, "price per row height mode" = "TICKSIZE");

                   else if thisBarMonthID == targetMonth then volp
                   else pocValue[1];

    def showPlot = thisBarMonthID > targetMonth;


    # Track breach
    def afterFormation = thisBarMonthID > targetMonth;

    # Regular intrabar touch
    def touchedBar = low <= pocValue and high >= pocValue;

    # Gap-cross detection (open on wrong side compared to prior close)
