Overnight High and Low

[rlohmeyer]

The following code is actually 2 separate indicators, which combined can give me the High and Low for the period between 1600 EST and 930 EST. However, it is not not an elegant solution since I generally have to uncheck the plot for one of the highs or lows to actually get the actual high or low for the period. I am not great with time functions. In any of you great coders could help it would be much appreciated. I have worked on ways to combine these 2 in some way but failed. @Mobious code is included and then additional code I scrounged. @SleepyZ @samer800 if you have time. I gave it about 18 hours and then gave up with my non-elegant solution below.

#Places vertical lines at start and end times and draws High and Low Lines


input onb = 1600;
input one = 930;
def SOD = secondsFromTime(1600) > 0;
def EOD = secondsFromTime(930) > 0;
def ST = SecondsFromTime(onb) ==0;
def ET = SecondsFromTime(one) ==0;
def OVN = Gettime() > sod;


AddVerticalLine(ST,"Market Open",Color.RED,Curve.points);
AddVerticalLine(ET," Market Closed",Color.RED,Curve.points);

input Date = 20130801;#hint Date: Set the date you want see.<b>\n(Enter in YYYYMMDD)</b>

def timeTest = getYyyyMmDd() == date;
def H = if timetest and sod then high else double.nan;
def L = if timetest and sod then low else double.nan;

plot HLine = highestall(h);
Hline.SetPaintingStrategy(PaintingStrategy.triangles);
Hline.setlineweight(3);
Hline.SetDefaultColor(Color.dark_green);
Hline.HideBubble();
Hline.HideTitle();


plot LLine = lowestall(l);
Lline.SetPaintingStrategy(PaintingStrategy.triangles);
Lline.setlineWeight(3);
Lline.SetDefaultColor(Color.dark_red);
Lline.HideBubble();
Lline.HideTitle();


#Mobius code...using a different method draws High and Low Lines for Globex but doesn't include after hours till midnight EST
def ph = high[1];
def pl = low[1];

def bar = BarNumber();

def GlobeX = GetTime() < RegularTradingStart(GetYYYYMMDD());


def ONhigh = if GlobeX and !Globex[1] then high else if Globex and
   high > ONhigh[1]then high else ONhigh[1];

def ONhighBar = if GlobeX and h == ONhigh then Bar else double.nan;

def ONlow = if GlobeX and !GlobeX[1]then low else if GlobeX and
  low < ONlow[1] then low else ONlow[1];

def ONlowBar = if GlobeX and low == ONlow then Bar else double.nan;
def OverNightHigh = if BarNumber() == HighestAll(ONhighBar) then ONhigh
                    else OverNightHigh[1];
def OverNightLow = if BarNumber() == HighestAll(ONlowBar)then ONlow
                   else OverNightLow[1];
def ONH_ = if OverNightHigh > 0 then OverNightHigh else Double.NaN;
def ONL_ =  if OverNightLow > 0 then OverNightLow else Double.NaN;


plot ONH = if Hline > ONH_ then Hline else ONH_;
ONH.SetPaintingStrategy(PaintingStrategy.triangles);
ONH.setlineweight(3);
ONH.SetDefaultColor(Color.dark_green);
ONH.HideBubble();
ONH.HideTitle();


plot ONL = if Lline < ONL_ then Lline else ONL_;
ONL.SetPaintingStrategy(PaintingStrategy.triangles);
ONL.setlineWeight(3);
ONL.SetDefaultColor(Color.dark_red);ONL.HideBubble();
ONL.HideTitle();

I found the answer with Anthropic AI help: Here is the code if interested:

# Overnight Market High and Low Indicator

def omo = 1600;  # Overnight Market Open
def omc = 930;   # Overnight Market Close

# Input for specific date
input Date = 20241126;  # hint Date: Set the date you want to see. (Enter in YYYYMMDD)

# Function to check if we're in the overnight session
def isOvernightSession =
    (getYyyyMmDd() == Date and secondsFromTime(omo) >= 0) or
    (getYyyyMmDd() == Date + 1 and secondsFromTime(omc) < 0);

# Vertical lines for overnight market open and close
AddVerticalLine(secondsFromTime(omo) == 0, "Overnight Market Open", Color.RED, Curve.points);
AddVerticalLine(secondsFromTime(omc) == 0, "Overnight Market Close", Color.RED, Curve.points);

# Capture high and low during the overnight session
def H = if isOvernightSession then high else double.nan;
def L = if isOvernightSession then low else double.nan;

# Plot highest high
plot HLine = highestAll(H);
HLine.SetPaintingStrategy(PaintingStrategy.triangles);
HLine.SetLineWeight(3);
HLine.SetDefaultColor(Color.GREEN);
HLine.HideBubble();
HLine.HideTitle();

# Plot lowest low
plot LLine = lowestAll(L);
LLine.SetPaintingStrategy(PaintingStrategy.triangles);
LLine.SetLineWeight(3);
LLine.SetDefaultColor(Color.RED);
LLine.HideBubble();
LLine.HideTitle();
