ORB custom column show calculations only for today

Hi Pete,

This custom column script gives the ORB pct but it doesn’t calculate it just for today. It will go back to the previous day’s last 30 minutes of options volume if today’s initial 30 minutes doesn’t have any. Is it possible to tweak it so that it only shows for today?

Thank you!

def orStartTime = 0930;
def orEndTime = 1000;
def openingTime = 0930;
def closingTime = 1600;
def targetPctOrMultiple = 5.0;

def na = double.nan;

def isOr = secondstilltime(orEndTime) > 0
and secondsfromtime(orStartTime) >= 0;
def isRegHrs = secondsFromTime(openingTime) >= 0
and secondsTillTime(closingTime) > 0;

# opening range levels logic
rec orhi =
if orhi[1] == 0
or isOr[1] == no
and isOr == yes
then high
else if isOr
and high > orhi[1]
then high
else orhi[1];

rec orlo =
if orlo[1] == 0
or isOr[1] == no
and isOr == yes
then low
else if isOr
and low < orlo[1]
then low
else orlo[1];

# plots
def orh = if isOr then na else orhi;
def orl = if isOr then na else orlo;

def ood = open(period = AggregationPeriod.DAY);

def targetMove = orl * (targetPctOrMultiple / 100);

def orlt = orl – targetMove;
def loss = (((close – orl) / orl)) * 100;

plot scan = if isOr then 0 else loss;
scan.assignValueColor(if close <= orlt then color.green else color.gray);
