Vertical Time Lines

[TraderMD]

Hello All, I have some knowledge of Thinkscript (enough to be dangerous ), but I am having a mental block on adding vertical lines to a chart from a specific starting point. What I am interested in achieving is from a specific starting point (ie Oct 13, 2022 - SPX low) placing a vertical line every 59 bars into the future. I am working on "Price and Time" moves (ie taking the square root of the low 3491 or 59) and marking every 59 bars in the future.

AddVerticalLine(SecondsFromTime(0930)==0,"Open",Color.Gray,Curve.SHORT_DASH);

I have tried adding different barcount calculations to the "SecondsFromTime(0930)==0" without success I assume there is an easy solution but am blanking. Any help would be greatly appreciated.

I'm not sure if this is exactly what you are looking for but here is something that will start at a specified time and print a vertical line every 60 bars (ie. 10:30, 11:30, 12:30 and so on for a 1m chart). It stops printing those lines at a specified time as well. Let me know how the square root stuff goes - it is very interesting.

input startTime = 0930;
input endTime = 1600;
input barCount = 60;
def isStart = SecondsFromTime(startTime)==0;
def RTH = SecondsFromTime(startTime)>=0 and SecondsTillTime(endTime) >= 0;
AddVerticalLine(isStart,"Open",Color.Gray,Curve.SHORT_DASH);

def count = if isStart then 0 else count[1] + 1;
def drawLine = count % barCount == 0;
AddVerticalLine(RTH and !isStart and drawLine,"Next Bar",Color.Gray,Curve.SHORT_DASH);

Hi FutureTony, thank you very much, above works great, now if we can figure out a way to not only set a time to start but also a date. But the above gives me something to work with, will keep you updated. Below is setting the start time to high at 1312 CST today. Need to figure out how to send a pic

I believe I am close but can't figure out what thinkscript function will perform the python Mod function. The below thinkscript produces and error in line 7 for the Mod function ?

input start_date = 20221013;
input bars_forward = 1;
input repeat_interval = 60;

def bars_since_start = if BarNumber() == 1 then 0 else if GetYYYYMMDD() >= start_date then BarNumber() - HighestAll(if GetYYYYMMDD() >= start_date then BarNumber() else 0) else Double.NaN;

def bars_until_repeat = repeat_interval - Mod(bars_since_start, repeat_interval);

plot line = if bars_until_repeat <= bars_forward and !IsNaN(bars_since_start) then high else Double.NaN;
line.SetStyle(curve.Short_DASH);
line.SetDefaultColor(Color.CYAN);

mod , is % symbol
look at this line in post2,
def drawLine = count % barCount == 0;

when the remainder of count/ barcount = 0 , then true.

-----------------

next time, don't type out a function and hope it exists. try looking it up.
( fyi, i tried, but couldn't remember which section mod was under , so i had to google it...
google.com thinkscript mod % )

Thanks for all the info Halcyonguy will update you all when finished

Hi Trader MD, were you able to resolve the issue of plotting limited vertical lines?
Regards

is there a way to draw vertical lines for every 40 days for any/each calendar year?

Would you want that to show on a daily chart or on every timeframe? And do you have a start date in mind?
