How to plot a horizontal line at the mid point of the high and low of 1st 15 minute candle

[Manfrom1968]

How to plot a horizontal line at the mid point of the high and low of 1st 15 minute candle of the day? What I've tried is not working and any help is appreciated. Thank you.

# Define the time frame for the first 15-minute candle
input marketOpenTime = 0930;
input firstCandleDuration = 15; ## 15 minutes

def is_first_candle = if SecondsFromTime(marketOpenTime) == 0 then 1 else 0;

def firstCandleHigh = high(period="DAY");
def firstCandleLow = low(period="DAY");
def firstCandleMidpoint = (firstCandleHigh + firstCandleLow) / 2;

def isFirstCandleClose = if is_first_candle and !is_first_candle[1] then close else Double.NaN;

# Plot the line on the chart
plot firstCandleCloseLine = if !IsNaN(isFirstCandleClose) then isFirstCandleClose else Double.NaN;
firstCandleCloseLine.SetDefaultColor(Color.GREEN);
firstCandleCloseLine.SetLineWeight(2);

# Plot the midpoint on the chart
plot firstCandleMidpointLine = if !IsNaN(isFirstCandleClose) then firstCandleMidpoint else Double.NaN;
firstCandleMidpointLine.SetDefaultColor(Color.BLUE);
firstCandleMidpointLine.SetLineWeight(2);

Replying from phone but try replacing the code defining the first 15m candle and the high and low of that with this:

def first15m_start = 0930;
def first15m_end = 0945;
def isfirst15m = secondsfromtime(first15m_start)>=0 and secondstilltime(first15m_end)<=0;
def first15m_low = if isfirst15m and low<=low[1] then low else if isfirst15m then first15m_low[1] else if secondsfromtime(first15m_start)>0 then first15m_low[1] else double.nan;
def first15m_high = if isfirst15m and high>=high[1] then high else if isfirst15m then first15m_high[1] else if secondsfromtime(first15m_start)>0 then first15m_high[1] else double.nan;

I think that will work if you update the code based on those replacements.

Thanks for the help Imk99.
