Extend Point of Control Line (Volume Profile) For ThinkOrSwim

yardley · Apr 10, 2022

Hi,

I need some help redoing the VolumeProfile Indictor that comes with ThinkorSwim. Here's my ask:

I want to present the VolumeProfile indicator on a chart such that the POC of control line extends all the way to the right axis. Here's a pic to demonstrate.
Image

The first image shows a chart that displays the daily Volume Profile with the blue line being the POC. In the second image, I manually drew a line that extends the POC line to the right with the price displayed at the end. Can someone help me replicate this with the existing VolumeProfile indicator that comes with ThinkOrSwim? I'm not very savvy with ThinkOrSwim script. Greatly appreciate any help.

Thanks again for checking the issue I was having and not understanding. I was having difficulty posting a screenshot of the issue; still not quite sure how to do that. Also, thanks for taking your time to investigate, ID the problem area, and providing a work-around. I am beginning to write code but at the moment I'm studying code and just modifying in some way....this slowly leads to better understanding for me.

Hey @SleepyZ. v good script! wondering if you ever encountered a bug with it not doing extensions for a current day? seems completely random like some days it'll plot and others it won't

This is set to 1hr and here's the version code i'm using

Code:

#Example_Prior Day_POC_Extended_until_Crossed_v1
#20171027 - BLT... chat request by Tb8... using parts of TOS VolumeProfile study to define POC
#Black lines are extended until POC crossed
#20210407 - BLT... usethinkscript request ... modified original c crosses criteria to high/low crosses/touches criteria... maybe easier to change criteria in the future by replacing parts of the 'or' statement to by what is desired (used notepad to find and replace criteria)

Hey @SleepyZ. v good script! wondering if you ever encountered a bug with it not doing extensions for a current day? seems completely random like some days it'll plot and others it won't

[Edit to add start that was not added to assignvaluecolor portion of code]

As this script has 90 iterations, it is likely not reliable on a chart with 90 days.

The following seems to work better.

The script has 30 iterations of the TPO POC from https://usethinkscript.com/threads/extend-point-of-control-line-volume-profile.10893/post-102451 . It has an input start to put the number for the next iteration to start (eg: 31, 61, ...).

I put 3 copies of the following on a 90 day chart with start settings of 0, 31, and 61. Performance and accuracy seems better than 1 version with 90 iterations, See the image below.

Ruby:

#TPO_Extended_POCs_HVAs_LVAs_for_x_Daysback_and_Limited_Plots_when_crossed
#More can be added using the logic below
#Sleepyz - usethinkscript request @yardlay
#Added HVA * LVA Lines and Plot limit when crossed for all 3;

script v {
    input daysback = 1;
def volp = reference TPOProfile("time per profile" = "DAY", "on expansion" = no, "price per row height mode" = "TICKSIZE");
def ymd  = GetYYYYMMDD();
def y    = if ymd != ymd[1] then y[1] + 1 else y[1];
def pc   = if IsNaN(close)
                  then pc[1] else
               if y == HighestAll(y) - daysback
                  then volp  else
               pc[1];
plot x    = if y > HighestAll(y) - daysback and Between(pc, low, high)

[Edit to add start that was not added to assignvaluecolor portion of code]

As this script has 90 iterations, it is likely not reliable on a chart with 90 days.

The following seems to work better.

The script has 30 iterations of the TPO POC from https://usethinkscript.com/threads/extend-point-of-control-line-volume-profile.10893/post-102451 . It has an input start to put the number for the next iteration to start (eg: 31, 61, ...).

I put 3 copies of the following on a 90 day chart with start settings of 0, 31, and 61. Performance and accuracy seems better than 1 version with 90 iterations, See the image below.

Honestly I can't get this TPO one to plot at all unless changing start to 0 but even then the extension seems to only work for current poc and then cuts to next one.

Is there not a way to have the first VPOC script just do a 5 day lookback or less? even just current day only would be amazing

These scripts are meant to be used on mutliple days, with the Volume Profile set to DAY. Your original request used a 90D, 1hr chart. It just needs the 3 scripts and VolumeProffile left to its' default setting of DAY.

Your settings on the 1st image was TODAY, 1m with what looks like 1hr VolumeProfile. The 2nd was 2D, 1m with a 1hr VolumeProfile. Neither will work properly.

See if that helps

I know it isn't how you designed the script it's just odd that the 1hr VPOC works consistently Mon, Tue, Wed, then stops working Thurs, Fri every week. A person mentioned to me that TOS doesn't have the proper data structures to store untested POCs

Here is an image of 90D 1hr\ES and Thursday/Friday appear using the script in post #4

That's good to know. Meant to say 1M chart / 1HR poc. like here it is good Mon-Tues perfect, then no Thurs-Fri -

Interestingly the a 1HR poc from Wednesday can extend through Thurs and Fri but it will stop plotting any new 1HR after Wednesday afterhours

That is not the script I posted with a recommendation to use. Nonetheless it looks like they stopped because they were touched. It also stops if there are not enough iterations to complete the loop being used to create the lines. The new script does not use that loop logic

Thanks @SleepyZ. I'm having issue with the script straight from #4 plotting lines at 0 (on both ES and NQ). I've tried multiple intervals with 30min timeframe. Any insight?

Longtime lurker here, first time posting. It doesn't appear I have ability to attach pictures yet.

I am not sure whether you mean the chart is set at 30m or the volumeprofile is set to a 30m timeframe. This indicator is meant to be on a volumeprofile with a DAY timeframe.

Here is /ES and /NQ on a 30m chart with the volumeprofile set to day and it appears to be okay using code #4.

Thanks for the response. I was trying to recreate that exact chart, volumeprofile set to DAY and a 30min timeframe. I was referring to the number of days in the chart (i.e. 30 D 30m)

I was able to uncheck "Fit Studies" on the y-axis scale drop down. But it's odd that if I select that box... the script plots lines in the value area, and vPOC as expected, but they are crammed up at the top and there are yellow/red lines plotted at 0.

For almost any study to display properly, I have found over the year's that all the check boxes shown in the image must be unchecked.

@SleepyZ Thanks for creating this script. It's pretty awesome.

I have a question. I usually trade volume profile off of the 30 min charts. Looking for stocks with Virgin point of Controls.

Is it possible to only extend Virgin Point of Controls on the chart? (Points of Control that have not been touched and once they have them no longer extended.)

Ultimately I would like use the indicator to create a scanner. That can scan for stocks with this setup. Since price tends to gravitate to these untouched levels.

Ps: Virgin Point of Control was how was taught to name them. Not sure if there's another name or not.

you can uncheck Show Plot in all of the vh/vl in Edit Studies. or comment them out in the script. the v1 - v10 are the POCs. if they are virgin or naked, the line would extend.

Here is the TPO script from above using VolumeProfile instead. Added is an input option to only show naked (virgin) plots.

The image uses a 1hr chart with 3 copies of the script starting at input start of 0, 30, and 90 and showing on naked plots, so more can be seen.

#VolumeProfile_Extended_POCs_HVAs_LVAs_for_x_Daysback_and_Limited_Plots_when_crossed

Can anyone help to show the prior days Value area on todays chart?

This will show the VAH, POC and VAL as lines on the chart. You can choose which day and whether to limit the display to today only.

Ruby:

input daysback        = 1;
input showontodayonly = yes;
def ymd      = GetYYYYMMDD();
def candles  = !IsNaN(close);
def capture  = candles and ymd != ymd[1];
def dayCount = CompoundValue(1, if capture then dayCount[1] + 1 else dayCount[1], 0);
def thisDay  = (HighestAll(dayCount) - dayCount) ;

def poc      = if thisDay == daysback then reference VolumeProfile("price per row height mode" = "TICKSIZE", "time per profile" = "DAY", "on expansion" = no) else poc[1];
def vahigh   = if thisDay == daysback then reference VolumeProfile("price per row height mode" = "TICKSIZE", "time per profile" = "DAY", "on expansion" = no).VAHigh else vahigh[1];
def valow    = if thisDay == daysback then reference VolumeProfile("price per row height mode" = "TICKSIZE", "time per profile" = "DAY", "on expansion" = no).VALow else valow[1];

plot poc1    = if thisDay > daysback or
                  showontodayonly and getday()!=getlastday()
               then Double.NaN
               else poc;
plot vahigh1 = if thisDay > daysback or
                  showontodayonly and getday()!=getlastday()
               then Double.NaN
               else vahigh;
plot valow1  = if thisDay > daysback or
                  showontodayonly and getday()!=getlastday()
               then Double.NaN
               else valow;

poc1.setdefaultColor(color.cyan);
vahigh1.setdefaultColor(color.yellow);
valow1.setdefaultColor(color.yellow);

input bubblemover = 3;
def b  = bubblemover;
def b1 = b + 1;
input showbubbles = yes;
addchartBubble(showbubbles and isnan(close[b]) and !isnan(close[b1]), poc1[b1], "POC - " + daysback, color.cyan);
addchartBubble(showbubbles and isnan(close[b]) and !isnan(close[b1]), vahigh1[b1], "VAH - " + daysback, color.yellow);
addchartBubble(showbubbles and isnan(close[b]) and !isnan(close[b1]), valow1[b1], "VAL - " + daysback, color.yellow);

I find that other Volume profile indicators produce different POC values. Some align while some dont, another indicator not at all.
Is there a preference to how POC is calculated, what time frame.. etc. ? Thanks

This looks great! thank you!
I Agree with @MP432, the Values are different compared to a standard VP. They are off by a few points in /ES
