Date Range Horizontal Lines

[british43]

I'm trying to plot horizontal lines for the high and low for a date range that extends with user input. The code I've messing around with is below.

input startdate = 20210719;
input enddate = 20210820;

def ActivePeriod = if DaysFromDate(startdate) >= 0 and DaysTillDate(enddate) >= 0 then yes else Double.NaN;

def vbegin = GetYYYYMMDD() == startdate;
def vend = GetYYYYMMDD() == enddate;

AddVerticalLine(vbegin, "Range Starts", Color.GREEN, Curve.FIRM);
AddVerticalLine(vend, "Range Ends", Color.GREEN, Curve.FIRM);


plot Test = if vbegin then Highest(high) else Double.NaN;
Test.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
Test.SetDefaultColor(Color.YELLOW);

plot Test1 = if vbegin then lowest(low) else Double.NaN;
Test1.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
Test1.SetDefaultColor(Color.YELLOW);

I'm trying to plot horizontal lines for the high and low for a date range that extends with user input. The code I've messing around with is below.

replace the last lines with these

#plot Test = if vbegin then Highest(high) else Double.NaN;
plot hi2 = if ActivePeriod then Highestall( if ActivePeriod then high else 0) else na;
hi2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
hi2.SetDefaultColor(Color.YELLOW);

def big = 999999;
#plot Test1 = if vbegin then lowest(low) else Double.NaN;
plot lo2 = if ActivePeriod then lowestall( if ActivePeriod then low else big) else na;
lo2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
lo2.SetDefaultColor(Color.YELLOW);

@halcyonguy Thanks! What would need to add to extend the lines?

@halcyonguy Thanks! What would need to add to extend the lines?

make new variables to get the high and low price levels on the end date.
then keep them and plot them till the last bar.

@halcyonguy I'm trying to get the count to work but it is not showing the right amount. What I'm doing wrong?

    # inputs
input startdate = 20210719;
input enddate = 20210820;

def ActivePeriod = if DaysFromDate(startdate) >= 0 and DaysTillDate(enddate) >= 0 then yes else Double.NaN;

def vbegin = GetYYYYMMDD() == startdate;
def vend = GetYYYYMMDD() == enddate;

def count2 = if startDate <= GetYYYYMMDD() then CountTradingDays( startDate, if( GetYYYYMMDD() < startDate, startDate, GetYYYYMMDD() ) ) else Double.NaN;

def v = round((count2/2),0);

addlabel(1, v, color.yellow);

AddVerticalLine(vbegin, "Range Starts", Color.GREEN, Curve.FIRM);
AddVerticalLine(vend, "Range Ends", Color.GREEN, Curve.FIRM);

#plot Test = if vbegin then Highest(high) else Double.NaN;
plot hi2 = if ActivePeriod then Highestall( if ActivePeriod then high else 0) else double.NaN;
hi2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
hi2.SetDefaultColor(Color.YELLOW);

def big = 999999;
#plot Test1 = if vbegin then lowest(low) else Double.NaN;
plot lo2 = if ActivePeriod then lowestall( if ActivePeriod then low else big) else double.NaN;
lo2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
lo2.SetDefaultColor(Color.YELLOW);

def mean = round((hi2 + lo2) /2,0);

plot m2 = if ActivePeriod then Highestall( if ActivePeriod then mean else 0) else double.NaN;
m2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
m2.SetDefaultColor(Color.YELLOW);

def count = if activeperiod and close crosses above m2
                       then 1
                      else if close > m2
                      then count[1] + 1
                      else count[1];

def count1 = if activeperiod and close crosses below m2
                       then 1
                      else if close < m2
                      then count1[1] + 1
                      else count1[1];
