I modified a copy of Mobius's Line At Price study, so it is not limited to just the last close price.
a modified version of
Line At Price
Mobius
Alternative to using the HighestAll() function
https://usethinkscript.com/threads/current-price-line-indicator-for-thinkorswim.8793/
this is the basic study , V00
it finds the lowest low on the chart.
Code:

# draw a line at the lowest low, without using lowestall()
input barsBack = 1000;
# if a small number is used, then only the last 'barsBack' quantity of bars on the chart will have a line.
# the preceding bars will have na and no line drawn
#input barsBack = 50;
# rule to find a price value
def low1 = if barnumber() == 1 then low
else if low < low1[1] then low
else low1[1];
# set the desired value on last bar and the bars after it
def low2 = if !IsNaN(close) and IsNaN(close[-1])
then low1
else low2[1];
# look at bars after the last bar and read the desired value
def lowline = if isNaN(close[-barsBack])
then low2[-barsBack]
else Double.NaN;
plot z = lowline;
z.SetLineWeight(2);
z.SetDefaultColor(Color.LIME);
z.SetStyle(Curve.MEDIUM_DASH);
addlabel( 1, "low line " + lowline, color.yellow);

this one, V01 , has more features and comments
..work with a price function/formula (this example uses low, and finds the lowest low).
..add a condition to define when to process data, when it is true. (it stops at the last bar)
....a vertical line is drawn at the start of the condition being true.
....a stop could be added by changing the condition to 0 before the lastbar, so it could find values within a range of bars.
..choose to disable the start condition and use all the bars on the chart.
Just like the original, it doesn't use lowestall() or highestall(). it uses a big negative offset number.
to change this for another purpose, change this formula,
def pricedata = low;
to change the condition enable time, change this formula,
def cond1 = (bn > 540);
to use all of the bars on the chart and ignore the condition, set this to yes
disable_start_condition_use_all_bars = yes
there are 2 test inputs.
..test1 all data
....draws a label that explains the bubble colors.
....draws bubbles with barnumber, low, and the lowest price.
......gray bubbles are before the condition and ignored.
......cyan bubbles are during the condition being true.
......1 green bubble is at the lowest level.
..test2 single bubble
....1 green bubble is at the lowest level.
i added comments to describe what each section is doing.
I like to explain things, sorry if this is a little wordy.
