Price Perfo

Years ago, I received this script
https://usethinkscript.com/threads/ytd-percent-issue-working-on-futures.1116/
by attending an AMTD webinar or from the Thinkscript lounge. Recently, I applied it to one of my charts and the labels do not appear. I have spent a fair amount of time trying to find the problem, unsuccessfully. There are no error messages.
It is a nice addition to a chart showing a label for the YTD, monthly, and weekly price changes.
Can someone fix the code?

Code:

# PercYMWTDpercRet2_Label_TOS_sha

declare hide_on_intraday ;

#def allows you to teach ThinkScript new "words" that you can reference later in your code
#GetYYYYMMDD() returns today's date
#there are 252 trading days each year

def yearstart = getyear() * 10000 + 101;
def tradedays = countTradingDays(yearstart ,  GetYYYYMMDD()) ;
def closeEOY = getvalue(close ,  tradedays ,  252) ;
def YTDnetchange = ((close - closeEOY)/closeEOY) * 100 ;

AddLabel(yes,  "Year: " + yearstart);
#YTDnetchange could have been the plot line ,  however to view results with a limited number of decimal places that line was another def or definition for ThinkScript.  And a new "word" value was used for the plot line in this code.  2 means round to 2 decimal places

def value = round(YTDnetchange ,  2) ;


#AddLabel tells ThinkScript how you want the results of your code diplayed.  Yes means do show the label.  Words or sybols in " " will appear with your label.
#This label could have been created complicated using concat function ... or the simplified method of using a + sign between values and text you want to appear in the label

AddLabel(yes ,  "YTD change: " + value + "%" ,  if value == 0
     then Color.LIGHT_GRAY
     else if value > 0
     then CreateColor(51 , 204 , 0)
     else color.RED) ;

#any watchlist column label can be quickly converted into a chart label via copy/paste/tweak into a new chart Study or Strategy.  HOWEVER AssignBackgroundColor on a chart label will change entire background of the chart when condition is met

#AssignBackgroundColor(if value < 0
#     then Color.RED
#     else if value > 0
#     then Color.GREEN
#     else color.LIGHT_GRAY) ;


#def monthstart = getMonth() * 10000 + 101 ;
#def tradedaysMTD = countTradingDays(monthstart ,  GetYYYYMMDD()) ;
#def MTDcloseEOY = getvalue(close ,  tradedaysMTD ,  21) ;
#def MTDnetchange = ((close - MTDcloseEOY)/MTDcloseEOY) * 100 ;

def MonthClose = if GetLastMonth() == GetMonth() then close(period = aggregationPeriod.Month)[1] else Double.NaN ;
def MTDnetchange = ((close - MonthClose) / MonthClose) * 100 ;

def valueMTD = round(MTDnetchange ,  2) ;

AddLabel(yes ,  "Month MTD change: " + valueMTD + "%" ,  if valueMTD == 0
     then Color.LIGHT_GRAY
     else if valueMTD > 0
     then CreateColor(51 , 204 , 0)
     else color.RED) ;



def WeekClose = if GetLastWeek() == GetWeek() then close(period = aggregationPeriod.Week)[1] else Double.NaN ;
def WTDnetchange = ((close - WeekClose) / WeekClose) * 100 ;

def valueWTD = round(WTDnetchange ,  2) ;

AddLabel(yes ,  "Week WTD change: " + valueWTD + "%" ,  if valueWTD == 0
     then Color.LIGHT_GRAY
     else if valueWTD > 0
     then CreateColor(51 , 204 , 0)
     else color.RED) ;

#AssignBackgroundColor(if value < 0

#def monthstart = getMonth() * 10000 + 101 ;

#def MTDcloseEOY = getvalue(close ,  tradedaysMTD ,  21) ;

     then Color.LIGHT_GRAY
     else if valueWTD > 0
     then CreateColor(51 , 204 , 0)
     else color.RED) ;

This should fix it to display. The problem was the dynamic offset in this line of 252 was too large.

def closeEOY = getvalue(close , tradedays , 252) ; replaced it with def closeEOY = getvalue(close , tradedays) ;
