Time Based Volume Indicator for ThinkorSwim

Volume is the second most important trading indicator, according to CustomizedTrading. Here is a quick snippet of their introductory to the indicator.

Time Based Volume completely eliminates the high volume distortion that occurs after the open of a market, just before the close of a market, and the low volume that occurs at market lunch times. Since the Time Based Volume Indicator is time based it will work on any intraday time based chart and symbol (including Forex).

Robert from Researchtrade was able to convert the Time Based Volume indicator over to ThinkorSwim. Here is the full script.

Notes:
  • Cyan = Bullish
  • Darker blue = Bullish smaller
  • Magenta = Bearish
  • Darker purple = Bearish smaller

Thanks, BenTen :) Given the importance of the relationship between Price and Volume, here is time based Volume and Price linked together by color:

Ben/Netarchitech, Can you confirm this will work 1day 1mintues? I see only on 5mts time frame.

@San I just checked again and it doesn't work for me on the 1m timeframe either. Sorry about that.

Hi all. I am looking for assistance for code that scans the first hour of the day for the past twenty days and compares it to the first hour of today's volume.

Example: 9:30-10:30 volume for today, 9:30-10:30 volume for last Friday, etc. etc. for the past twenty (or specified) days. This way you can plot to see what % of volume today is returning compared to other opening days. Not just the last twenty hours.

Thank you.

This plot only compares the last twenty hours. It does not compare the first hour of the day for the past twenty days. Any help?

Use FB as an example on the 20D 1H plot. If you go into Excel and plot the volume from 9:30 to 10:30 for the past twenty days and average them out, you'll get an average of 4,537,000 (rounded). If this code is true, then today's volume from 9:30-10:30 would have been 140% (this morning we saw approximately 6,368,000 shares traded). BUT, this plot gives us a value of 333%...odd. So, I recorded hourly volume for the past 20 hours and took an average, which was 1,912,794. Today's morning volume? 3.33x that number. So, that proves that this is not taking the first hour of each day, but the last 20 hours. Read through the code and you can confirm this with the fold idx loop. Any help would be appreciated @BenTen


@horserider any ideas here?

short answer, try turning off extended hours.

long answer
I think robert's study is working as intended. In my modified version of it, values are displayed that match up to values of previous bars.

Most stocks will have a different quantity of bars (trades) in after hours, from one day to the next. Because of this you can't count x bars back and get to the same time of day. Roberts volume study looks back x number of bars, it doesn't check for time of day. It is looking back multiples of 390, to find previous days data. It uses the chart time to determine how many bars exist during a day on the chart. A trading day has 390 min, 6.5 hrs.

I modified robert's study, so it will show values in bubbles, that can be compared. I changed the length from 20 to 3. That should be enough values to see what is going on. In the bubbles are several variables. It reads the volume from 3 bars in the past. I divided all the numbers by
1000, to reduce the quantity of digits displayed. The values should be unique enough to verify the data. A day has 6.5 hours. so if a chart is set to 1 hour, nbars will be 7 , 6.5 rounded up. Every 7th bar, the bubbles are yellow, to make it easier to find and compare the values.

the variables are, starting from the top,
volume0 , current bar volume
volume1 , a bar that is [1 * nbars] ago , using getvalue
volume2 , a bar that is [2 * nbars] ago , using getvalue
volume3 , a bar that is [3 * nbars] ago , using getvalue
sum of 3 volumes shown above
pvsum variable
pvavg variable
volpct

Say the current time is 9am, I want to find all stocks whose volume upto 9am today is n times the average volume up to 9am of m previous days.

I tried to look at the script of AverageVol. The function Average() just takes the whole period average. I don't see how to adapt it to just take acount into the volume upto now for each previous days.

Code:
declare lower;
declare zerobase;

input length = 50;

plot Vol = volume;
plot VolAvg = Average(volume, length);

Vol.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
Vol.SetLineWeight(3);
Vol.DefineColor("Up", Color.UPTICK);
Vol.DefineColor("Down", Color.DOWNTICK);
Vol.AssignValueColor(if close > close[1] then Vol.color("Up") else if close < close[1] then Vol.color("Down") else GetColor(1));
VolAvg.SetDefaultColor(GetColor(8));

i'm not sure, but i think the code to do this, may be too complex to run in a scan.
the code from the link below could be altered to work on chart. maybe on a short watchlist?

Could anyone help me to modify this study to work as a watchlist column? I can do fine tuning and color tweaks and such once it's in the format, but I am not clear on how to make the critical changes to def's and plots. Thank you!

def lastDn = if IsNaN(lastDn[1]) then 0 else if (close < open) then VolPct else lastDn[1];

#NOTE: I have removed the exact volume number, it's hidden. If you want to have it instead of it being hidden, just substitute the addLabel code with this addlabel(yes, vol, color.black); You still need the assignbackgroundColor line to have the background change.

def Vol = VolPct;
addlabel(yes, vol, if (close > open) and (VolPct > lastUp[1]) then Color.CYAN else if close > open then CreateColor(0, 128, 128) else if close < open and VolPct > lastDn[1] then color.magenta else color.plum);

Another option for the addLabel is this:
addlabel(yes, roundup(vol,0), color.black);

Basically this will give you the whole number, rounded up. Check the screenshot.

Just adding a screenshot of how the original code from the original post #1 of this thread. Here is what Robert said incase the website gets deleted. this is just for archiving, since this appears to be a overlooked indicator due to some confusion on how it was intended to work.

1689916911219.png
 
Unless I'm reading this indicator wrong this doesn't seem to work correctly. The bars at the opening and close are always higher than the bars in the middle of the day. If it was truly comparing each bar to the previous n days exact time of day bar average then shouldn't only the bars that are higher than the average be up?
 
Does anyone know how to get this to work on /ES time frames lower than 15min? I changed line:

def nbars = RoundUp(390/ nMinutes, 0);

to

def nbars = RoundUp(1380 / nMinutes, 0);

and that works for time frames 15min and higher but lower time frames 10min and 2min did not work. I was messing around with the highest number that would still show a value on the 10min and it was (990 / nMinutes); so it seems that the fold function has a limit of 99 instances. Is there a workaround or is this a limiting factor? Thanks!

Have you found the answer to this? There has to be because I've seen people with ToS Relative Time of Day Volume displaying on 1 minute charts. So either we're close with this code or there's an entirely different way of finding the solution (other than counting back bars)

Hello @BenTen , I just now saw your post...
All evening I was following up on a request for a time based relative volume for intraday as the Daily Relative Volume that is often used at a 60 period length would be useless to observe Volumes for Opening and Closing trends.

I used some Mobius Techniques to solve Relative Volume differently, My script used way more lines of code but on the bright side by finding Relative Volume by cutting Times into slots seems to allow some other functionalities.

Where would you like me to post this?
If you have time would you and @MerryDay please share any thoughts or criticisms before I share this with others.

Thank you so much for all the order you bring to the community.
Have a Happy NewYear if I don't see you for awhile.

Relative Volume Calculation to compare the Volume of Order flow to other days at the exact same time of days. Corrected for all time frames including days including days with unequal trading hours.

The next task will probably be to automate some of the Volume Analysis to be more compact to the human eyes.
As always I'm grateful for all criticisms and suggestions.

Happy Holidays.

@MerryDay @BenTen @shakib3585 @lmk99
