Returning True For Current Candle and Every Same Candle For Prior Days

I'm trying to figure out how I can write thinkscript to return true for the current candle and every candle of the same time period on the chart, and then automatically roll forward as time progresses. For example, If the current time was 10:00AM, It would return true for every 10:00AM candle, and then when it changed to 10:01, all of the 10:01 candles would return true.

Any thoughts on if this is possible?

Wow Josh thank you so much. That is exactly what I was looking for.

I spent the morning trying to implement it into the code I posted above. Unfortunately, it renders it too slow to be useful. I think because the frequent updating to pull in tick-by-tick volume data causes the complex code to re-run every tick and it can't keep up.

If there was a way to prevent your section of code from refreshing until the new candle is created, I think that would solve the problem.

Here is the code that combines the two:
Code:
declare on_volume;
declare zerobase;

input includeCurrentDayInAvg = no;
input barsToBeIncluded = {default OnlyCurrentBar, CurrentAndBefore, CurrentAndAfter};
input includePremarket = no;
input includePostmarket = no;
input...
When I plot this on the chart, it returns 9:30.

plot time = gettime();
plot open = RegularTradingStart(GetYYYYMMDD()) + 1;
addverticalline( time == open);

However, I'm stumped as far as how to manipulate it to move as the candles move.
 

Join useThinkScript to post your question to a community of 21,000+ developers and traders.

You can use the SecondsTillTime() and SecondsFromTime() functions to locate the 10:00 candles:
Code:
def TenOclock = if SecondsTillTime(1000) == 0 and SecondsFromTime(1000) == 0 then 1 else 0;

def TenClose = if TenOclock == 1 then CLOSE else double.nan;

plot Ten = TenClose;

Then you can do whatever you want with the data in the TenClose holder.

Happy Trading,

I'm trying to get it to move automatically as the day progresses. So It would return true for every 10:00 candle, and then automatically switch to 10:01, etc without having to go in and update the code every minute. I updated the question so that it's clearer.
 
We can solve for the current time like this:
Code:
def timeNow = (getTime());
def hour = (timeNow % 86400) / 3600;
def minute = (timeNow % 86400) / 60 / 60 / 24 * 60;
 
def hourmin = hour * 100 + minute;

def TenOclock = if SecondsTillTime(hourmin) == 0 and SecondsFromTime(hourmin) == 0 then 1 else 0;

BUT

ToS won't let us use a variable in the Seconds functions...
'''
Only constants expected here: hourmin CL constant function parameter 'tillTime' at 16:36
Only constants expected here: hourmin CL constant function parameter 'fromTime' at 16:70
Only constants expected here: hourmin CL constant function parameter 'tillTime' at 16:36
Only constants expected here: hourmin CL constant function parameter 'fromTime' at 16:70'''

So there really isn't a good way to go about what you're looking for that I can see.

Not so helpful, but perhaps a little bit.

EDIT:
Looking at the math for determining hours and minutes, I'm not sure I've got the minutes worked out quite right... use at your own risk

Yeah unfortunately that's the issue I'm running into as well. Still working through one possibility but I doubt it's going to work. It's a shame because it would be nice to get price and volume averages for each candle.
 
Here is the code I've settled on. If anyone knows of a way to have the time variable roll forward automatically, I would be eternally grateful if you shared.

Code:
declare on_volume;
declare zerobase;

input time = 0930;
input barwidth = 3;
input showVolume = yes;
input highlightDataPoints = yes;

def TimeBarWeAreLookingFor = SecondsTillTime(time) == 0;

def CurrentDay = GetDay() == GetLastDay();   #this removes current bar from average.

def NumOfInstances = if TimeBarWeAreLookingFor and CurrentDay == no
            then NumOfInstances[1] + 1
            else NumOfInstances[1];

def CumVol = if NumOfInstances != NumOfInstances[1]
                then CumVol[1] + volume
                else CumVol[1];

addverticalline(highlightDataPoints and NumOfInstances != NumofInstances[1],NumOfInstances != NumofInstances[1]);
addverticalline(highlightDataPoints and TimeBarWeAreLookingFor and CurrentDay == yes, TimeBarWeAreLookingFor and CurrentDay == yes,Color.yellow);

def AvgVol = Round(CumVol / NumOfInstances, 0);
def Percent = (volume / AvgVol) * 100;

AddLabel(1, "Current Candle: " + volume, Color.WHITE);
AddLabel(1,ROUND(Percent,2) + " %",if
Between(percent,100,110) then CreateColor(136,252,172)
                        else if Between(percent,110,120) then CreateColor(106, 252, 104)
                        else if percent >=120 then Color.Green
                        else if Between(percent,80,90) then Color.Pink
                        else if Between(percent,70,80) then  CreateColor(206,74,116)
                        else if percent <=80 then Color.Downtick
                        else Color.white);
AddLabel(1, "Avg Vol: " + AvgVol, Color.ORANGE);
AddLabel(1, "Prior Candles: " + CumVol, Color.ORANGE);
AddLabel(1, "Avg Over: " + NumOfInstances, Color.ORANGE);

# Plotting of the bar graph--------------------------------------------------------
plot CurrentCandleVolume = If ShowVolume then volume else Double.NaN;
CurrentCandleVolume.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
CurrentCandleVolume.SetLineWeight(barwidth);
 
Ruby:
declare upper;
def DayRoll =
    if GetDay() != GetDay()[1]
    and !IsNaN(close)
    then GetTime()
    else DayRoll[1]
;
def Time =
    if !isNaN(close)
    then GetTime()
    else double.nan
;
def aRoll = HighestAll(DayRoll);
def aTime = HighestAll(Time);
def aBarTime = aTime - aRoll;
def BarTime = Time - DayRoll;
def isSameBar = BarTime == aBarTime;
AddVerticalLine(isSameBar,"Same Bar",Color.green);

Well, I generally avoid yellow triangle of doom code to begin with in my personal scripts, but it seems that highest all may have been throttled recently? I found a post from August speaking about this as a recent change. However, I believe this explanation may be incorrect. The issue actually seems to be that a once_per_bar declaration is being forced without consent, rather than a column/scan type update frequency being implemented. I will have to look into it more.
