Price Percentage Change indicator help

Hi
i want to make an indicator that plots the price percentage change of 2 symbols between any timeframe’s current price and that symbol’s prior day’s US market close. below is what i have so far.
i got this “price percentage change with histogram” to plot the difference between 2 symbols correctly on a “Daily” timeframe chart only. the code makes the calculation based off the prior “bar’s” close. i want to make it so the calculation of the prior bar is always the prior “day’s” US market close. it plots on lower timeframe charts like a 1-minute chart but it plots the change from the prior bar’s close which is just 1 minute prior and does not calculate it from the prior “Day’s” US market close like i want it to.
any ideas? charts attached for more clarity. any help would be greatly appreciated. Many Thanks.
below is the code on TOS for this:

#works on daily chart, need to get it to work on any timeframe like 1 minute
declare lower;

#Symbol Input
input SYMB1 = “PEP”;
input SYMB2 = “KO”;

def Price1 = close(symbol = SYMB1)[1];
def Price2 = close(symbol = SYMB1);

def Price3 = close(symbol = SYMB2)[1];
def Price4 = close(symbol = SYMB2);

plot PercentChg1 = ((Price2 – Price1) / Price1)*100;
plot PercentChg2 = ((Price4 – Price3) / Price3)*100;

plot Hist = (PercentChg1-PercentChg2);
Hist.setPaintingStrategy(paintingStrategy.HISTOGRAM);
Hist.setLineWeight(5);
Hist.assignValueColor(if PercentChg1 >=PercentChg2 then color.green else color.red);

******* below is extra code which might help ********************

plot DailyClose = close(period=”DAY”)[1];

#HINT: This study plots a chart label for Net Change and Percent Change from prior close (regardless of time period of the chart.

input period_Type = AggregationPeriod.DAY;

def begin = close(period = period_Type)[1];
def end = close(period = period_Type);
def NetChg = end – begin;
def PctChg = (end / begin) – 1;

AddLabel(yes, “Change from Prior close: ” + AsDollars(NetChg) + ” ” + AsPercent(PctChg), if NetChg > 0 then Color.GREEN else if NetChg < 0 then color.RED else color.LIGHT_GRAY);
