Finding the First and Last Bar of the day in ThinkorSwim

isnt allowing me to add image
but heres a link
i guess the code would be something like this but for last bar of day

#CODE BELOW
AddLabel(1, "52Week HIGH = " + Highest(high(period = AggregationPeriod.Week),52), Color.plum);
AddLabel(1, "52Week LOW = " + Lowest(low(period = AggregationPeriod.Week),52), Color.plum);
#END CODE

This is data off the last bar shown as a label and with lines

Ruby:
def lasthigh  = if IsNaN(close[-1]) and !IsNaN(close) then high else lasthigh[1];
def lastclose = if IsNaN(close[-1]) and !IsNaN(close) then close else lastclose[1];
def lastlow   = if IsNaN(close[-1]) and !IsNaN(close) then low  else lastlow[1];

plot lhigh   = if !showlines then double.nan else lasthigh;

plot llow    = if !showlines then double.nan else  lastlow;
lhigh.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

addlabel(showlabels, "Close Bar: " + astext(lastclose), color.yellow);
AddLabel(showlabels, "Low Bar: " + AsText(lastlow), Color.RED);

awesome thank you,,,,,,

are you able to modify this code to where it only shows text on the chart bubbles but not the price didgits??

how about first bar of day? some stocks like to pull back to the open and bonce, is there a way to plot a line for the close of the first bar of day instead of chart bubble
 
how about first bar of day? some stocks like to pull back to the open and bonce, is there a way to plot a line for the close of the first bar of day instead of chart bubble

This will plot the open at premarket and regular trading hours as horizontal lines.

Ruby:
def open_pre = if gettime() crosses below regularTradingEnd(getyyyYMMDD()) then open else open_pre[1];
plot pre_open = open_pre;
pre_open.setpaintingStrategy(paintingStrategy.HORIZONTAL);
pre_open.setdefaultColor(color.cyan);

def open_rth = if gettime() crosses above regularTradingstart(getyyyYMMDD()) then open else open_rth[1];
plot rth_open = open_rth;
rth_open.setpaintingStrategy(paintingStrategy.HORIZONTAL);
rth_open.setdefaultColor(color.magenta);
 
I came across this script which it has helped TREMENDOUSLY so thank you for that! However, how do I script for the strategy to NOT take a trade at the last bar? For clarification, I am telling the strategy to close out any trades on the last bar (that part is working just fine) but on rare occasions, the conditions of the strategy are being met RIGHT AT THE LAST BAR OF THE DAY and therefore the strategy is entering into a new trade while simultaneously closing any existing trades. Any help on how to tell the strategy to NOT TAKE A NEW POSITION ON THE LAST BAR OF THE DAY? Thank you in advance.

Figured out my own question. If anyone wondering, just add

LastBarofDay[-1] is False

and it won't take an entry on the last bar.

How would I count the number of bars since the first bar?

Example: I want to count the number of bars since a higher time frame opened.(day, week, month, etc.).

(Why I want this: I run into back-testing issues where if I reference higher time frame, that higher time frame can report data based on what happened later, versus the status of that higher time frame on that exact bar. This thread kinda explains my issue:

https://usethinkscript.com/threads/...-data-back-testing-versus-live-testing.10366/

My hope was that if I could count the number of bars since the higher time frame opened, I could derive the high/low at a bar based on getting the highest/lowest values up until that bar occurred. This would then make it a lot easier to test mutliple time frame, versus only being able to test multiple time frame by advancing in on-demand, or advancing with live data.

You can't backtest MTF indicators due to the repainting. In real-time, a 1hr indicator on a 5-min timeframe will repaint for 12 bars. In backtesting it will already be repainted yielding results not possible to obtain in real trading.

I'm aware of that limitation.

I'm looking for a solution that steps outside of multiple time frames to provide what I'm looking for. I don't know if "virtual" time frame better communicates what I'm driving at, or not.

I'm looking for a virtual time frame that is an accumulation of the lower time frame, and thus get away from the multiple time frame/multiple aggregation issues. What I'm envisioning would be possible if I could figure out how to count bars since period began.

That is, to approximate this:
Code:
def WeeklyHigh = High(period = AggregationPeriod.WEEK);
def WeeklyLow = Low(period = AggregationPeriod.WEEK);
def DailyHigh = High(period = AggregationPeriod.DAY);
def DailyLow = Low(period = AggregationPeriod.DAY);

I want to do this instead:
Code:
def count_of_days = <<number of days since the week started>>;
def VirtualWeeklyHigh = highest(high(period=AggregationPeriod.DAY), count_of_days);
def VirtualWeeklyLow = lowest(low(period=AggregationPeriod.DAY), count_of_days);
def DailyHigh = High(period = AggregationPeriod.DAY);
def DailyLow = Low(period = AggregationPeriod.DAY);

Because the "virtual" week is simply an accumulation of days, I don't have to reference the AggregationPeriod.WEEK time frame in the second code. My challenge is figuring out "count_of_days" (or any alternative to get what I'm looking for).

Also, if I back-tested the virtual week, Monday and Tuesday would have different "count_of_days", so it would be back-test friendly.

Hope this explains the idea a bit better.

Well, I've been able to determine that this method I'm proposing won't work as simply as I propose, because the highest() & lowest() functions require constants, and won't accept dynamic values. ... It was worth a shot at least ... :D
 
well can't you just count how many bars there are in the lower timeframe to make up the length of the longer timeframe to simulate and then use those long lengths instead of your original ones? I hope that made sense :)
Hahahaa, so funny (were you snooping on me the other day as I was having this conversation with MsTradeCombine):

How about I use 5 days for virtual week, 21 days for virtual month, etc. Thus, my virtual weekly high = highest(high, 5), and virtual quarter high = highest(high, 63), etc.?

If you didn't mean it that way, let me know. I like new ideas. :D

I should probably test the 5/21/63/252 study (this technique is already used by some for moving averages and what-not), and it's not quite the same as MTF, but maybe I'm too rigid to want a virtual MTF in the first place.
 
i don't think i've seen any other threads by u :) but what i do to avoid the MTF strategy pitfalls is simulate the length on the smaller timeframe for example if i want to see the (thirty minute time frame) 4 length RSI on the 5 min chart ill calculate 4 x 6 = 24 length. I do this with all my studies.

Here's what I would do to simulate what you're looking for. Is there a way to incorporate the day count? If so, could you share that maybe? I've been meaning to learn how to code that kind of thing but haven't got around to it yet. This is basically just Daily High Low (td study) with a rolling length plot.

here's a slightly different way to do it using FIRST

here is an example

Code:
#First Bar Close and Volume of REGULAR TRADING HOURS

def mktOpen = SecondsFromTime(0930) == 0 or GetDay() <> GetDay();

#First Bar Info
def high1 = First(close);

#Define  Todays First Bar Close
def today_firstbarclose = if mktOpen and high1 then close else today_firstbarclose[1];
#Define  Todays First Bar Volume
def today_firstbarvol = if mktOpen and high1 then volume else today_firstbarvol[1];

#Label
AddLabel(yes, " Todays First RTH Bar Close =" + today_firstbarclose, Color.LIGHT_GRAY);
AddLabel(yes, " Todays First RTH Bar Volume =" + today_firstbarvol, Color.LIGHT_GRAY);
 
this is for a request from here,
https://usethinkscript.com/threads/...hourly-candle-high-and-low-with-labels.15416/
to modify the code in post#1 to show prices in labels for several days

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

show labels with, the high and low from the last x days,
from the first and/or last bars of the day.

pick first bar, last bar, or both
pick a quantity for recent days to look at, 1 to 8

a couple of test bubbles can be turned on see some prices and counts.

day 1 is the current day. day 2 is the previous one, 3 is before that,...

How to find the first "First Bar of Day"? I can get it by using barNumber() if there are no extended hours. But I want to keep the Extended Hours enabled.
 
How to find the first "First Bar of Day"? I can get it by using barNumber() if there are no extended hours. But I want to keep the Extended Hours enabled.
