Date Math and display the date on the chart

gravity2726 · Sep 9, 2021

For example :

to_date=20211008
X=10 days
Need to add 10 days to to_date and display the date on the chart;
If possible ; Even if the date is in the future

This looks for the last trading day for the days you input the prior trading date.

THANK YOU!

One last thing, I'm then trying to calculate CALENDAR days between that date and last_trading_day (most recent trading day) but am not getting the label to show up. Can you please check what I'm doing wrong?

Ruby:

def num_calendar_days = DaysFromDate(TD_daysback);
AddLabel(1, num_calendar_days, Color.WHITE);

Probably because that is not logical, the code for which I did not make an error routine in it, cannot handle it.

Great It is working Sleepz...Is it possible to add the X_date in the calculation; I mean if days= 3 and X_Date=20210912.....It is showing the calendar date 15SEP2021; Instead it should add the current day and provide me 14SEP2021....Where I can change in the code to do it.

This may not always work as TOS only plots trading days. Moreover, the way the X_date had to be deconstructed to add days, provides no easy way to construct a date from that code. So this workaround code finds the first date of the year and month and constructs a yyyyymmdd that can be used to reconstruct the new calendar date.

You can choose to display an arrow and/or verticalline() on this date if it is a trading day or the nearest trading day to it.

As you can see in the picture below, it will plot into the right expansion, even though are no candles currently plotted there.

Code:

how can I have thinkscript pull a closing price for specific date and trade based of that price. for example lets say i want to buy if the price is above closing price of june 1 and sell if the price is below the closing price of june 1.

MerryDay · Sep 18, 2021

@acadiasw The ToS does not allow auto-trading. And this type of complex date math would be beyond what is allowed to us in conditional orders.

Hello all,
I'd like to get the price of the first trading day of a month? How does it work? Is anybody able to help? Thanks in advance

@pmettler if you want to display the date on a chart, read through the above posts. But these scripts will be too complex to use in scans or conditional orders.

Hello MerryDay, now I was looking for the close of the first trading day of a month in order to calculate the performance since the beginning of the month.

I figured it out:

declare lower;

plot zero = 0;

#Defines Start of the Year
def yearstart = GetYear() * 10000 + 101;

#Defines Start of the Month
def monthstart = GetYear()*10000 + Getmonth()*100 +1;

def closeOnDate = if GetYYYYMMDD()[1] < monthstart and GetYYYYMMDD() >= monthstart then close else closeOnDate[1];

plot PercentChg = 100 * (close - closeOnDate) / closeOnDate;
PercentChg.AssignValueColor(if PercentChg > 0 then Color.GREEN else if PercentChg == 0 then color.light_GRAY else Color.RED);
PercentChg.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

def newMonth = GetMonth() != GetMonth()[1];
AddVerticalLine(newMonth, (GetMonth()), color.black, curve.Short_Dash);

@SleepyZ , various studies have start/end RTH inputs (e.g. input start = 0930; input end = 1600; ). Is it possible to get those values dynamically for the current selected ticker?

Here is a study by Mobius that uses gettime to do that. These generally work if there is activity in post/pre market as it requires gettime() to cross some form of regulartradinghours(). If there is none of that activity, then especially the regular trading hour start will not work.

Ruby:

# GetTime() and Regular Trading Start / End Functions
# Mobius
# 4.27.2018

# TOS could write 4 functions or 2 and allow a different cross
# case to determine which to plot
#
# Here are the 3 RegularTradingStart() functions as you'd expect. 
# Whether you use cross, cross above or cross below, it's all
# the same
#
# RegularTradingEnd() can be the RTH end or Extended Hours End
# depending on the cross selection. Cross by itself will get both

def RTHstart = GetTime() crosses above RegularTradingStart(getYYYYMMDD());
def RTHEnd   = GetTime() crosses above RegularTradingEnd(getYYYYMMDD());
def ExtEnd   = GetTime() crosses below RegularTradingEnd(getYYYYMMDD());
plot x=rthstart;
x.setpaintingStrategy(paintingStrategy.BOOLEAN_ARROW_UP);
addVerticalLine(RTHStart, "RTH Hours Begin", color.cyan, curve.firm);
addVerticalLine(RTHEnd, "RTH Hours End", color.cyan, curve.firm);
addVerticalLine(ExtEnd, "Extended Hours End", color.cyan, curve.firm);
# End

THANK YOU!!

If there's no activity, would there be a way to set a fallback time to 0930-1600? Would it return NaN or something that can be used in if condition to set the default in that scenario?

Edit: was actually playing around with this. Is there a way to save the values themselves (not boolean outcome) in a variable?

This seems to work for regulartradingstart.. AFL did not have premarket on numerous days on the top chart in the picture below with the original code. The lower chart is the same set up as the upper, but with the code below.

I did not find any examples of the other regulartradingend applications, but something similar to the regulartradingstart fix should work. I included a 1600 possible fix, but was unsure what you may run into if you even use the extended application.

Ruby:

def RTHstart = GetTime() crosses above RegularTradingStart(GetYYYYMMDD());
def RTHEnd   = GetTime() crosses above RegularTradingEnd(GetYYYYMMDD());
def ExtEnd   = GetTime() crosses below RegularTradingEnd(GetYYYYMMDD());
plot x =  RTHstart or SecondsFromTime(0930) == 0;
x.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
AddVerticalLine(RTHstart or SecondsFromTime(0930) == 0, "RTH Hours Begin", Color.CYAN, Curve.FIRM);
AddVerticalLine(RTHEnd   or SecondsFromTime(1600) == 0, "RTH Hours End", Color.CYAN, Curve.FIRM);
addVerticalLine(ExtEnd , "Extended Hours End", color.cyan, curve.firm);

Thank you for the update.

I'm trying to run the following example from jshingler.

Code:

input start = 0930; #Start of RTH for most securities 
input end = 1600; #End of RTH for most securities
def toPaint = SecondsFromTime(start) >= 0 and SecondsTillTime(end) > 0;
def up = if toPaint then Double.POSITIVE_INFINITY else Double.NaN;
def down = if toPaint then LowestAll(low) else Double.NaN;
AddCloud(up, down, Color.RED);

You see how it has start and end are hardcoded. I'm trying to make that dynamic and paint the cloud for ANY securities (some futures have different start/end RTH e.g. \CL). When I add the following on top "def RTHstart = GetTime() crosses above RegularTradingStart(getYYYYMMDD());" and use that in line #3 "def toPaint = SecondsFromTime(RTHstart) >= 0" it throws an error. Do you know how I can get \CL's "start" so that I can use it in SecondsFromTime?
