Yesterday High & Low RTH

Hi guys, I am trying to find a study on ToS that plots yesterday’s high and low but only during RTH. I have found a few studies that get pretty close but they are missing one thing or another, (some of them only chart the high and low levels on that day, not on the current trading day). This study is the best I have but it includes extended or overnight trading hours. Does anyone how I can get yesterday’s high and low levels for Regular Trading Hours only? Thanks

I got this code from another user. Username: True, from another site.

#hint:<b>Plots the high, low and close and open of inputted days ago</b>\n The plots persist across to the right of the chart.\n Bubbles identify the plots.\nWorks for all aggregations thru ‘Day’.

declare upper;
declare hide_on_daily;
input DaysAgo = 1;#hint DaysAgo: Excludes today
input PlotHigh = yes;
input PlotLow = yes;
input PlotClose = yes;
input PlotOpen = no;
input ShowBubbles = yes;

def AdjDaysAgo = DaysAgo + 1; #Adjusted to match a true LastDate which includes today

def day = GetDay();
def lastDay = GetLastDay();
def year = GetYear();
def lastYear = GetLastYear();
def yyyymmdd = GetYYYYMMDD();
def lastDate = HighestAll( if day == lastDay and year == lastYear then yyyymmdd else Double.NaN );
def currentDate = if yyyymmdd < lastDate then yyyymmdd else lastDate;
def tradingDaysAgo = CountTradingDays( currentDate, lastDate );
def previousDayPlus = tradingDaysAgo <= AdjDaysAgo;
def today = lastDate == currentDate;

script previousPlot {
input today = no;
input previousDayPlus = no;
input data = high;

plot previousPlot = if previousDayPlus then
HighestAll(if today then data else Double.NaN)
else Double.NaN;
}

plot previousHigh = previousPlot(today, PlotHigh and previousDayPlus, high( period = “DAY” )[DaysAgo]);
plot PreviousLow = previousPlot(today, PlotLow and previousDayPlus, low( period = “DAY” )[DaysAgo]);
plot PreviousClose = previousPlot(today, PlotClose and previousDayPlus, close( period = “DAY” )[DaysAgo]);
plot PreviousOpen = previousPlot(today, PlotOpen and previousDayPlus, open( period = “DAY” )[DaysAgo]);

#=========== Chart Bubbles ===================
def FirstBar = ShowBubbles and today != today[1];
AddChartBubble(FirstBar, previousHigh, (“High of ” + DaysAgo + ” day(s) ago”), color = previousHigh.TakeValueColor());
AddChartBubble(FirstBar, PreviousLow, (“Low of ” + DaysAgo + ” day(s) ago”), color = PreviousLow.TakeValueColor());
AddChartBubble(FirstBar, PreviousClose, (“Close of ” + DaysAgo + ” day(s) ago”), color = PreviousClose.TakeValueColor());
AddChartBubble(FirstBar, PreviousOpen, (“Open of ” + DaysAgo + ” day(s) ago”), color = PreviousOpen.TakeValueColor());
