Horizontal Lines In ThinkOrSwim

Joaqvil · Aug 13, 2021

Hello there, need help.
I thought it was something basic, but I couldn't find nothing among the answers.
I would like to plot horizontal lines among consecutive prices, por example:
plot each 0.5 dollars,
plot each 1 dollar,
plot each 5 dollars,
plot each 10 dollars,

Would be 4 plots in total , so I can activate and deactivate them as I want. If its a penny stock I would use every 0.5 and if its AMZN I would use every 10..

The solutions I previously find suggest to put it manually, for example:
plot line1 = 5;
plot line2 = 10;
And you end up with hundreds of plots..
Im sure there is a more efficient way.

This may give you some ideas. There are no ways around having to create a 'plot' for each line. However, this can automate it somewhat. Add more lines and style by copying and pasting the current 7 groups and make the minor changes.

Ruby:

def price  = if SecondsFromTime(0930) == 0 then open else price[1];
def xopen  = if GetDay() == GetLastDay()
             then
             HighestAll(if IsNaN(close[-1]) and !IsNaN(close)
                        then open(period = AggregationPeriod.DAY)
                        else 0)
             else Double.NaN;
def range  = if Between(xopen, 0, 2)
             then .10 else
             if Between(xopen, 2, 100)
             then .25 else
             if Between(xopen, 100, 500)
             then 1.0     
             else
             10.0;

plot x1_       = xopen - range;
plot x2_       = xopen - range * 2;
plot x3_       = xopen - range * 3;
plot x4_       = xopen - range * 4;
plot x5_       = xopen - range * 5;
plot x6_       = xopen - range * 6;
plot x7_       = xopen - range * 7;


plot x1       = xopen + range;
plot x2       = xopen + range * 2;
plot x3       = xopen + range * 3;
plot x4       = xopen + range * 4;
plot x5       = xopen + range * 5;
plot x6       = xopen + range * 6;
plot x7       = xopen + range * 7;

input lines = {default LINE, POINTS};
def paint = if lines == lines.POINTS then PaintingStrategy.POINTS else  PaintingStrategy.LINE;

x1.SetPaintingStrategy(paint);

thank you for posting this @SleepyZ. i learned something. i don't think i have seen a varaible used to hold a PaintingStrategy before.

to everyone who is learning thinkscript, take the time to read/skim through the codes that are posted on this site, even if you think you know the headline topic. sometimes you come across a different way of doing something. sometimes you may learn something.
i almost skipped over this post, because i know how to plot a line. luckily i didn't.

the study uses input to choose 1 word from several. then uses the value to determine the value for another variable, to set the PaintingStrategy.

Okay.. I manage arrange this, now i'm stuck.
What I want to do, is to take the open price of the day, round it, and then plot 7 horizontal lines above and below the open.
The problem is i would like the lines to extend to the left forever, straight, tidy, without gaps or anything.
And I'm not being able to achieve that.

Code:

input aggregationPeriod = AggregationPeriod.day;

def Open = Round(open(period = aggregationPeriod)[1], -1);

def range  = 5;

plot x1_       = Open;
plot x2_       = Open - range;
plot x3_       = Open - range * 2;
plot x4_       = Open - range * 3;
plot x5_       = Open - range * 4;
plot x6_       = Open - range * 5;
plot x7_       = Open - range * 6;


plot x1       = Open + range;
plot x2       = Open + range * 2;
plot x3       = Open + range * 3;
plot x4       = Open + range * 4;
plot x5       = Open + range * 5;
plot x6       = Open + range * 6;
plot x7       = Open + range * 7;

input lines = {default LINE, POINTS};
def paint = if lines == lines.POINTS then PaintingStrategy.POINTS else  PaintingStrategy.LINE;

x1.SetPaintingStrategy(paint);
x2.SetPaintingStrategy(paint);
x3.SetPaintingStrategy(paint);
x4.SetPaintingStrategy(paint);
x5.SetPaintingStrategy(paint);
x6.SetPaintingStrategy(paint);
x7.SetPaintingStrategy(paint);

x1.SetDefaultColor(Color.GRAY);
x2.SetDefaultColor(Color.GRAY);
x3.SetDefaultColor(Color.GRAY);
x4.SetDefaultColor(Color.GRAY);
x5.SetDefaultColor(Color.GRAY);
x6.SetDefaultColor(Color.GRAY);
x7.SetDefaultColor(Color.GRAY);

x1_.SetPaintingStrategy(paint);
x2_.SetPaintingStrategy(paint);
x3_.SetPaintingStrategy(paint);
x4_.SetPaintingStrategy(paint);
x5_.SetPaintingStrategy(paint);
x6_.SetPaintingStrategy(paint);
x7_.SetPaintingStrategy(paint);

x1_.SetDefaultColor(Color.GRAY);
x2_.SetDefaultColor(Color.GRAY);
x3_.SetDefaultColor(Color.GRAY);
x4_.SetDefaultColor(Color.GRAY);
x5_.SetDefaultColor(Color.GRAY);
x6_.SetDefaultColor(Color.GRAY);
x7_.SetDefaultColor(Color.GRAY);

See if changing open to this does what you want.

Code:

def Open = highestall(Round(open(period = aggregationPeriod)[1], -1));

I have a study that posts an arrow whenever a condition is met. What I want is for it to plot a line all the way across the chart after "x" condition is met and to always have that level be there. Just adding more levels the more the condition is met. Right now it only plots up to the next signal of the same type.

MerryDay · Aug 26, 2021

@Bobby There is no generic element that plots a horizontal line after a specific condition. Lines are defined within studies based on what the specific condition is that is triggering them.
However, the syntax is similar in most cases. So here are some of the top results of my search on horizontal line.

Bobby · Aug 26, 2021

@MerryDay so basically what I am looking for is it already plots a line after a condition but it goes away after the condition is met again and is replaced by the new line. I can post an image example too. But basically, I want each new trigger to show up as a new line instead of replacing an old line

Just adding more levels the more the condition is met. Right now it only plots up to the next signal of the same type.

As MerryDay indicated there is no easy way to plot multiple horizontal lines across the chart. Here is an example of how to do 5 or less horizontal lines plotted across the chart based upon a 'cond'. You can easily make additional conditional plots by copying/pasting/editing from the existing plots in this code.

Ruby:

input display = 5;
input price   = high;
def cond      = if MACD().diff crosses 0 then 1 else Double.NaN;
def condx     = if !IsNaN(cond) then condx[1] + 1 else condx[1];
def xcond     = if condx != condx[1] then condx else Double.NaN;

plot x1 = HighestAll(if display >= 1 and (condx) == HighestAll(xcond) - 0 then price else Double.NaN);
x1.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
plot x2 = HighestAll(if display >= 2 and (condx) == HighestAll(xcond) - 1 then price else Double.NaN);
x2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
plot x3 = HighestAll(if display >= 3 and (condx) == HighestAll(xcond) - 2 then price else Double.NaN);
x3.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
plot x4 = HighestAll(if display >= 4 and (condx) == HighestAll(xcond) - 3 then price else Double.NaN);
x4.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
plot x5 = HighestAll(if display >= 5 and (condx) == HighestAll(xcond) - 4 then price else Double.NaN);
x5.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

DefineGlobalColor("x", Color.CYAN);
x1.SetDefaultColor(GlobalColor("x"));
x2.SetDefaultColor(GlobalColor("x"));
x3.SetDefaultColor(GlobalColor("x"));
x4.SetDefaultColor(GlobalColor("x"));
x5.SetDefaultColor(GlobalColor("x"));

trying to get several lines plotted above the zero line for reference of macd and signal line extended

There are several posts about plotting lines. Here is one of them.

Hello, first time posting here. Please be kind if this is a dumb question.

I am trying to plot a defined length line, from the current date, for n# bars in the past. I use Ichimoku, so I'd like to be able to plot a line that goes back in the past for 26 bars from the current bar. Is that something that is possible to do in Thinkscript? I can write basic thinkscript, but cannot figure out how to do this.

I very much appreciate any suggestions that you can offer.

Thank you,

Mike M

Here's one way

Ruby:

input barsback = 26;
def last  = HighestAll(if !IsNaN(close) and IsNaN(close[-1]) then BarNumber() else 0);
plot Data = if Between(BarNumber(), last - barsback, last) then close(period = AggregationPeriod.DAY) else Double.NaN;

Code:

plot signal = HighestAll(if display >= 1 and (cond1x) == HighestAll(x1cond) - 0 then price else Double.NaN);
     signal.setpaintingStrategy(PaintingStrategy.dashes);
     signal.setDefaultColor(Color.cyan);
     signal.SetLineWeight(3);

plot signalx = HighestAll(if display >= 2 and (cond1x) == HighestAll(x1cond) - 1 then price else Double.NaN);
     signalx.setpaintingStrategy(PaintingStrategy.dashes);
     signalx.setDefaultColor(Color.cyan);
     signalx.SetLineWeight(3);

plot signalxx = HighestAll(if display >= 3 and (cond1x) == HighestAll(x1cond) - 2 then price else Double.NaN);
     signalxx.setpaintingStrategy(PaintingStrategy.dashes);
     signalxx.setDefaultColor(Color.cyan);
     signalxx.SetLineWeight(3);

plot signalxxx = HighestAll(if display >= 4 and (cond1x) == HighestAll(x1cond) - 3 then price else Double.NaN);
     signalxxx.setpaintingStrategy(PaintingStrategy.dashes);
     signalxxx.setDefaultColor(Color.cyan);
     signalxxx.SetLineWeight(3);

plot signalxxxx = HighestAll(if display >= 5 and (cond1x) == HighestAll(x1cond) - 4 then price else Double.NaN);
     signalxxxx.setpaintingStrategy(PaintingStrategy.dashes);
     signalxxxx.setDefaultColor(Color.cyan);
     signalxxxx.SetLineWeight(3);

@MerryDay @SleepyZ so in watching this using this code the line shows up after the signal but doesn't stay at the signal, it moves with the highs of following candles instead of just staying put, and I'm not sure why

So I can't post all of the code because it isn't public access the conditions triggering the line, but the above code is the only "plot" code in the study, so nothing else should be causing the plot to change

if we can't see what formulas you have for
cond1x and x1cond,
and formulas supplying them,
it will be near impossible to help you.

@Bobby Thank you for not posting proprietary content. Questions for commercial indicators need to be directed to the vendor.

Hello my fellow code geeks -

I've been a long time admirer of this community and i learnt little coding.
i was looking for SR Lines (Support Resistance lines) that joins two or more candles that has same close price. Something like below snip.
