ThinkScript for Cycle Brackets

Picard

Member
I'm looking for a way to code an indicator for equal cycles like the built in indicator called "Cycle Brackets" that I can start at a specific date. Even though this is a built-in indicator, I would like to do this with ThinkScript or any other way to indicate equal cycles.

is there a way to have TOS provide a counter that indicates the number of bars /days/weeks in the cycles it is drawing?
 
Follow up question this. I can configure the Cycle brackets to show vertical lines at 9 period intervals. However, it does not stay saved. As soon as I pull up a different ticker, the drawing goes away. I tried to save the study and the style with the cycle brackets, but am missing something. I'd like this to become part of my study set so I don't have to configure the darn things again and again. What am I missing?

Clarification: The drawing stays with the ticker, so if I return back to that same ticker, the cycle brackets show fine.

Perhaps, the cycle brackets is not the way to go. So looking for a simple way to draw vertical lines at m y defined interval and be able to choose style and color of line
 
So after researching vertical lines, ToS has this simple default code

Code:
input period = {WEEK, default MONTH};
AddVerticalLine((period == period.WEEK and GetWeek() <> GetWeek()[1]) or (period == period.MONTH and GetMonth() <> GetMonth()[1]), "", Color.ORANGE, curve.SHORT_DASH);

If someone can help me update this to include:
  • Specific period lines in days (example 9 days)
  • ability to change color and line type

UPDATE:
Using the DAYS option was causing all sorts of issues, so I have decided to go with periods. That actually works well for me
Here's the code I'm using.

Code:
input periods = 9;
AddVerticalLine(BarNumber() % periods == 0, "", Color.Violet, curve.SHORT_DASH);

Can someone help me add options so the color and line style is user configurable?

draw repeating vertical lines, based on some time period
. based on a chosen time: day , week, month
. and a quantity to skip: 1+

example,
day 6 , draws a vertical line at the start of every 6th day

can pick a color, based on getcolor , 10 choices

can pick the line type, although it doesn't work perfectly. can pick a couple types. zooming may affect what is seen.


Code:
# cycles_periods_lines_01

#https://usethinkscript.com/threads/thinkscript-for-cycle-brackets.4891/#post-119704

def na = double.nan;
def bn = barnumber();

# valid price ?  price enable
def pr_en = !isnan(close);

def d = getday();
def w = getweek();
def m = getmonth();

def daycurrent = d == getlastday();

def daynew = d != d[1];
def weeknew = w != w[1];
def monthnew = m != m[1];

# period counts, used by % formulas
def daycnt = if bn == 1 then 1
 else if daynew then daycnt[1] + 1
 else daycnt[1];

def weekcnt = if bn == 1 then 1
 else if weeknew then weekcnt[1] + 1
 else weekcnt[1];

def monthcnt = if bn == 1 then 1
 else if monthnew then monthcnt[1] + 1
 else monthcnt[1];

#-------------------------

input period = {default Day, Week,  Month };
input qty = 3;

#def charttime = GetAggregationPeriod();
#def en = if period >= charttime then 1 else 0;

#----------------------------
#  pick color
# https://usethinkscript.com/threads/format-watchlist-text-in-thinkorswim.4045/page-3#post-67014
#  this doesn't assign the color in quotes.
#  the location of the picked color in the series, is changed to a number
#   ex. pink is the 3rd number.  3 is saved in color1_choice
input Color1_choice = {default "magenta", "cyan", "pink", "gray", "orange", "red", "green", "dark_gray", "yellow", "white"};

#AddLabel(yes, "test1 " + Color1_choice , GetColor(Color1_Choice));
#---------------------------

input line_type = {default LINE, dashes, POINTS};


addlabel(1, "  ", color.black);
addlabel(1, qty, color.yellow);
addlabel(1, period, color.yellow);
addlabel(1, "  ", color.black);


# getday is a day # that includes weekends...  so doesn't work for this
#def xd = (d % qty) == 0; 

#def xd = if qty == 1 then 1 else ((daycnt % qty) == 0);
def xd = ((daycnt % qty) == 0);
def xw = ((weekcnt % qty) == 0);
def xm = ((monthcnt % qty) == 0);

def xd2 = if qty == 1 then daynew else (!xd[1] and xd);
def xw2 = if qty == 1 then weeknew else (!xw[1] and xw);
def xm2 = if qty == 1 then monthnew else (!xm[1] and xm);

def x = if period == period.day then xd2
 else if period == period.week then xw2
 else if period == period.month then xm2
 else 0;

def p = pr_en and x;

AddVerticalLine(p, "-", GetColor(Color1_Choice),
(if line_type == line_type.POINTS then PaintingStrategy.POINTS
 else if line_type == line_type.dashes then PaintingStrategy.dashes
 else PaintingStrategy.LINE));



#--------------------------
# test stuff


input test1 = no;
addchartbubble(test1, low,
daycnt + "\n" +
xd + "\n" +
weekcnt + "\n" +
xw + "\n" +
monthcnt + "\n" +
xm + "\n" 
, color.yellow, no);


# change plot type , kind of works
#input line_type = {default LINE, dashes, POINTS};
#input test3 = no;
#addverticalline(test3 and daycurrent, "z", color.white, 
#(if line_type == line_type.POINTS then PaintingStrategy.POINTS
# else if line_type == line_type.dashes then PaintingStrategy.dashes
# else PaintingStrategy.LINE));

in the comments, at the end of this study, are notes about picking a line type
https://usethinkscript.com/threads/...remove-it-once-price-hits-it.5257/#post-75706


3 links on drawing arcs and lines
one link is about drawing ovals. the oval code could be modified and added to this, to draw half circles
https://usethinkscript.com/threads/drawing-cones-ovals-arcs-in-thinkorswim.12839/#post-109233


https://tlc.thinkorswim.com/center/reference/thinkScript/Constants/PaintingStrategy
it is possible to use a number for a painting strategy, when plotting a line.
it may or may not help in picking a type in this study
x.SetPaintingStrategy(6);
