How to plot horizontal lines at price levels where the price ends with a certain number

Hi All,

New to the forum and trying to learn thinkscript...I'd like to create an indicator that plots horizontal lines at price levels where the price ends with a certain number (user input number), i.e. userPriceEndsWith = "1.50" so we want to plot horizontal lines at every price level on the chart where the price ends with "1.50"

What I'd like to do is plot horizontal lines at 1.50, 11.50, 21.50, 31.50 etc

How can one do this in thinkscript? Are there loops in the language? Any example(s) would be greatly appreciated

Thanks in advance for all your help!

I want to draw 2 horizontal lines across my charts (for daily and weekly views) where the high horizontal line is defined as the high of the first trading day of any week (obviously this is usually Monday unless a holiday week) and the low horizontal line is the low of the first trading day of the week. So these horizontal lines will change each week as new First Trading Day of the Week Highs and lows change. I would like the lines to persist on both daily and weekly charts.

This seems to work as you want for daily, however Monday is not available on weekly.

Code: 
input show_last_only = no;
def start_day_week   = if GetWeek() != GetWeek()[1]
                       then if GetDayOfWeek(GetYYYYMMDD()) == 1...

you will need a plot function for each line you want. fold loops can repeat a formula x times, but it returns 1 number value. they can't include a plot. you can't have a loop repeat a plot many times.

below are ideas and formulas, may not be exact thinkscript codes.
the below formulas create instantaneous values.
you will have to search and find a study code that plots price line levels.

so you may want to do something like draw 3 lines above the current price, and 3 lines below it.
you could create a formula to find a multiple of 10, that is closest to the current price. call it baseline.

def basefactor = round( close /10, 0);
def baseline = basefactor * 10;

then add 3 numbers to it for lines above and subtract 3 numbers, for lines below.

def line1up = baseline + (10 + your number) ;
def line2up = baseline + (20 + your number) ;
def line3up = baseline + (30 + your number) ;

def line1dwn = baseline - (10 + your number) ;
def line2dwn = baseline - (20 + your number) ;
def line3dwn = baseline - (30 + your number);

then apply horizontal line formulas ( highestall(.... or whatever ) to each of the 7 values above.

here is an example code that draws a horizontal line.

here is a working study
it can plot up to 5 lines above and below the reference level, at some factor

Code: 
# horz_lines_increm_near_close_0

# plot some quantity of horizontal lines,
# above and below a reference price near the close.
# the ref price is a multiple of the spacing_factor, that is closest to the close.

# Line At Price
# Mobius
# Alternative to using the HighestAll() function
def barsBack = 1000;
def c = if !IsNaN(close) and IsNaN(close[-1])
        then close
        else c[1];
#plot line = if isNaN(close[-barsBack])
def line = if isNaN(close[-barsBack])
            then c[-barsBack]
            else Double.NaN;
#line.SetLineWeight(1);
#line.SetDefaultColor(Color.LIME);
#line.SetStyle(Curve.MEDIUM_DASH);

def na = double.nan;
input quantity_of_lines = 4;
def q = quantity_of_lines;

input spacing_factor = 0.5;
def basefactor = round( line/spacing_factor, 0);
def baseline = basefactor * spacing_factor;

plot b = baseline;
b.SetLineWeight(1);
b.SetDefaultColor(Color.LIME);
b.SetStyle(Curve.MEDIUM_DASH);

addlabel(1, " ", color.black);
addlabel(1, "baseline " + baseline, color.yellow);

plot line5up = if 5 > q then na else baseline + (spacing_factor * 5);
plot line4up = if 4 > q then na else baseline + (spacing_factor * 4);
plot line3up = if 3 > q then na else baseline + (spacing_factor * 3);
plot line2up = if 2 > q then na else baseline + (spacing_factor * 2);
plot line1up = if 1 > q then na else baseline + (spacing_factor * 1);

plot line1dwn = if 1 > q then na else baseline - (spacing_factor * 1);
plot line2dwn = if 2 > q then na else baseline - (spacing_factor * 2);
plot line3dwn = if 3 > q then na else baseline - (spacing_factor * 3);
plot line4dwn = if 4 > q then na else baseline - (spacing_factor * 4);

I changed this study slightly to meet my needs for trading futures. All lines are 1 color, 5 lines, in each direction, and they are demarcated by 100s.

is there a way to change the B value to pick the daily open instead of current close price? I want to be able to draw lines above and below the daily open automatically. if possible be able to enter individual value to each line for example:

aboveline2 = +15
aboveline1 = +10
dailyopen price = 1
belowline1 = -5
belowline2 =-25

sorry for asking to custom this. this is actually a great study indicator.

no need to be sorry, ask your questions.

here is a study that draws a horizontal line from the open of the day.
then draws up to 4 other lines, based on offset numbers.
if a number is 0, then no line is drawn.

Code: 
# lines_from_dayopen

can this be done in 2 time frames, 9:30 to 1:00 then it resets again from 1:00 to close of market?

Great work. I was wondering if there is a way to draw horizontal lines up and down to infinity or a really high amount from a number I enter. For instance let's say I enter 100 and I wanted it to draw a line every ten pts up and down from the forever is that possible? I really appreciate your help.

ι don't know if this the right place to post a simple huge stupid script that draws 50 lines btw 2 prices by a flexible increment .here it is :
# Inputs for the start and end levels and interval
input startLevel = 17000;
input endLevel = 22000;
input interval = 100;

# Calculate the number of lines to be drawn
def numberOfLines = (endLevel - startLevel) / interval;

# Plot horizontal lines at each interval
plot line1 = if startLevel + interval * 0 <= endLevel then startLevel + interval * 0 else Double.NaN;

I want to draw 2 horizontal lines across my charts (for daily and weekly views) where the high horizontal line is defined as the high of the first trading day of any week (obviously this is usually Monday unless a holiday week) and the low horizontal line is the low of the first trading day of the week. So these horizontal lines will change each week as new First Trading Day of the Week Highs and lows change. I would like the lines to persist on both daily and weekly charts.

yes that is possible, but
you can't use plot within a loop,
so you need a plot statement for every line you want on a bar.
if you want 100 lines going over 1 bar, you need 100 plot statements and 100 sets of variables and formulas to support the plots. very tedious.
i'm not going to spend hours making that. you can learn thinkscript and modify my code in post #5
https://usethinkscript.com/threads/...-ends-with-a-certain-number.7692/#post-107271

or try post 16 code. maybe that will work for you

This seems to work as you want for daily, however Monday is not available on weekly.

Code: 
input show_last_only = no;
def start_day_week   = if GetWeek() != GetWeek()[1]
                       then if GetDayOfWeek(GetYYYYMMDD()) == 1
                            then 1
                            else 2
                       else start_day_week[1] ;
def h   = if GetDayOfWeek(GetYYYYMMDD()) == start_day_week then high(period = AggregationPeriod.DAY) else h[1];
def l   = if GetDayOfWeek(GetYYYYMMDD()) == start_day_week then low(period = AggregationPeriod.DAY) else l[1];
