How to Track Percent Change From Open in ThinkOrSwim

[@TOSIndicators]

thinkScript Code: def openPrice = if SecondsTillTime(930) == 0 then open else openPrice[1]; def pctChangeFromOpen = (close - OpenPrice) / OpenPrice; AddLabel(yes, AsPercent(pctChangeFromOpen), color.black); AssignBackgroundColor(if pctChangeFromOpen > 0 then color.green else color.red);

[@richfree5365]

Thank you! 👍 How about if you want to see what they call the Absolute % change from the open in order to see what's moving the most regardless if the asset is up or down?

[@richfree5365]

Is this correct for absolute change? Based on my math research. Absolute change equation is (final - initial). So, I'm assuming the (close - openprice) without dividing. thinkScript Code: def openPrice = if SecondsTillTime(930) == 0 then open else openPrice[1]; def pctAbsoluteChangeFromOpen = (close - OpenPrice); AddLabel(yes, AsPercent(pctAbsoluteChangeFromOpen), color.black); AssignBackgroundColor(if pctAbsoluteChangeFromOpen > 0 then color.green else color.red);

[@TOSIndicators]

I think you would want to use the abs value function: tlc.thinkorswim.com/center/reference/thinkScript/Functions/Math---Trig/AbsValue

[@chezblunts]

Do you put (930) regardless for what time zone you're in, or should you adjust for your time zone?

[@AtomicHorror135]

THANK YOU SO MUCH!!! BEEN LOOKING FOR THIS FOR A LONG TIME, ITS VERY USEFUL!

[@beachbum4232]

Very kind of you to put this code out for free. Much appreciated

[@TOSIndicators]

My pleasure. Happy New Year!

[@baritony8763]

I can't tell you how happy I am to find this video. Most %'s include premarket & it can be misleading as to what is truly rising most after open. But isn't there any alternate adjustment you can make on TOS to achieve this---just out of curiosity? I've been searching to no avail. And also, I think you mentioned a different way(when you jotted the word "OPEN") before you brought up the steps (chart, watchlist ,settings gear, customize,etc) . I learned so much just from this. Thank you very much!

[@TOSIndicators]

That makes me happy to hear... I'm glad it was helpful!

[@jnrbond28]

This is Excellent!!! Just what I was looking for. Thank You.

FWIW, I just learned why the column does not sort properly. AddLabel uses alphanumeric sort so you need to use plot instead. def openPrice = if SecondsTillTime(930) == 0 then open else openPrice[1]; plot pctChangeFromOpen = (close - OpenPrice) / OpenPrice *100; pctChangeFromOpen.AssignValueColor(color.Black); AssignBackgroundColor(if pctChangeFromOpen > 0 then color.green else color.red);

[@andrewf2204]

Thank you!

[@TonioXenon]

Here is the simple version: def openPrice = open; def closePrice = close; def percentChange = (closePrice - openPrice) / openPrice * 100; plot PercentChangeFromOpen = percentChange;

[@MichaelMeettomarry]

Very helpful. Would Love to see a video on creating Volume Buz

[@GB-kl2pd]

Hello. I really appreciate this indicator. Would you say that this is better than the built in percent change indicator in TOS? Thanks.

[@TOSIndicators]

I think so.

[@neoshred]

This is really helpful. Im trying to do the same thing but on a TOS scanner instead of a watchlist but the code doesnt seem to work there. Any suggestions?

[@TOSIndicators]

You'll need to tweak the code from outputting via a label to a plot variable instead, which becomes your scan condition. Some of our scan tutorials should help, with showing you how to do this: www.tosindicators.com/scans

[@neoshred]

@@TOSIndicators I watched a bunch of the videos and tried to tweak it but Im new at thinkscript so I still couldn't get it. Any help would be appreciated. Id be willing to pay if need be.

[@TOSIndicators]

No worries... feel free to send an email at [e-mail], and I can do my best to help you out.

[@victorabdelmalek7530]

I'm looking to do the same thing. Did you ever figure this out?

[@ki5ngau]

Brilliant!

[@cornellm2985]

Thanks man

[@BlackViperOfDorne]

Is there a way to start the time frame at 4am pre-market trading start? I tried changing 930 to 400 in the code and it gave me the same results.

[@huckaflowco7777]

I need a label that will compare the charts percentage from the open to the spy's percent from the open, can you please make a video for this? I found a label like this but it doesn't start from the open it starts from the beginning of the day but that just doesn't work for me it has to be from bell ring.

[@matthewhunter6938]

Solid bro

[@srinip825]

Very nice. Is it possible to use this against multiple watch list list and count number of stocks positive close and negative close ? Watchlist1 ,number of stocks close by open,close of open Watchlist2, Watchlist3, Apply this as a study with label to any stock chart? Thamks

[@TOSIndicators]

Hi Srini - I don't believe what you've described is currently possible using thinkScript.

[@darckfire]

Awesome.

[@PEOdysseus]

very cool - I would like something similar with volume - I would like to know the 2 min and 5 mins volumes for the current day and what about it is higher than the previous day and what amount is it is higher than the previous 5 days on their opening 2 min and 5 min timeframes. similar thing in the last hour of the trade - how does the volume compare in percentage. can you help me with this?

[@TOSIndicators]

You should be able to follow a similar process as we did for price, but scale it to the appropriate time frame's volume you're looking for, and output that in a watchlist.

[@FloydCheong]

thks for this ! u are super nice ! now my % from open have too many digit , like 4.9596% , how can I make all this only 2 digit after dot ? i use script from ur web , cos i think that s latest ? appreciate all the help , wish u best !

[@TOSIndicators]

Glad it helped! You can use the Round function to round to 2 digits after the decimal. Documentation here: tlc.thinkorswim.com/center/reference/thinkScript/Functions/Math---Trig/Round

[@FloydCheong]

@@TOSIndicators thks , just right now , my open % sorting , if there s 16% , it sort as 1% , sort group as 1% , after 5%4%3%2%16% can i fix this ?

[@vastaction]

Are those buy and sell ticks, arrows on your chart. I've been pulling my hair out trying to make that happen. Is it possible to script that. I just want a simple arrow/tick showing where I buy and sell. Seems so simple. I enter them manually after each trading day using the notes. Ahhh, please tell me that's possible and how to make that happen.

[@technow4514]

Very helpful

[@TOSIndicators]

Glad to hear it!

[@richardaron5095]

Thanks! How to add this as a label to the chart?

[@TOSIndicators]

Hi Richard - you should be able to use the same code, and paste as a study, instead of a watchlist custom quote column. You may need to modify the formatting (ie. eliminate AssignBackgroundColor() and incorporate color logic into the AddLabel() function instead).

[@richardaron5095]

@@TOSIndicators Cool, thank you very much! Love your channel.

[@rcook924]

I didn't see the code pasted anywhere in the comments (unless I missed it). I can get the code from the video but usually your final version is usually slightly different.

[@TOSIndicators]

Hi Richard - sorry about that, just posted & pinned the comment. Thanks for catching that!

[@shwe7211]

Thanks a lot.

[@healthyblend2048]

Whenever I input the code, the “change from open” says “infinity.” Any suggestions? Thank you for the tutorial!

[@windcarve]

Is there a way to get the % change from open values to correctly sort by increasing or decreasing values? Once the value exceeds 10% or 20%, things don't sort correctly. For instance, I'm looks at a ground of stocks in (supposed to be) decending order: 9.51%, 8.4%, 5.45% 27.78%, 16.02%, 14.91%, 1.6%, 0.43%... then similar for a group of negative values. All the % change from open codes I've come across seem to have this problem (incorrectly sorting percentage values). Thank You - enjoying your content very much.

[@TOSIndicators]

Hi windcarve - that's strange... I haven't encountered that issue, but I'll take a look and let you know if I can find any easy solutions.

[@jnrbond28]

Is there away to see the "Dollar" amount instead of "Percentage"?

[@TOSIndicators]

Yep - you can adjust the formula calculation to output the $ amount, instead of dividing to achieve the percentage.

[@jnrbond28]

@@TOSIndicators Nice one thank you!

[@elitanug289]

It is possible to have different colors if the % keep increasing, like from 3-5% yellow, 5-10% orange, 10-15% purple, etc

[@TOSIndicators]

Hi Elitanu - yes, it should be. You would need to 'spell out' the different tiers in the color section of the code (or create separate boolean variables outside of the label function, and plug them in).

[@elitanug289]

@@TOSIndicators can you show me how or copy the keys?

[@krahsloop]

Thanks so much for sharing this! Maybe an odd question here, but is there a way to modify this code so that it tracks percentage change starting from the day's closing bell (4:00pm) up until the end of after hours/calendar day? I tried using 1600 instead of 0930 but that does not seem to yield anything. Thanks again!

[@TOSIndicators]

Hi Scott - Try using something like a 5m chart, with the 'Incl extended hours" checkbox turned on. I tested with /ES, and it tracks the correct open, used in the calculation.

[@krahsloop]

@@TOSIndicators That did the trick, thank you again!

[@markgoodman6199]

Is there any way to just change the color of the actual number to red and green instead of the background???

[@TOSIndicators]

Hi Mark - You can use the AddLabel() function if you'd like to change only the color of the number, and not the background.

[@KimYeoman]

This is exactly what I was seeking, thank you so much! I am trying to change the code so that the text is red/green, not the background. I was able to get rid of the background colour, but the text is stuck on white. How do I get the actual text to change red/green? Thanks again! def openPrice = if SecondsTillTime(930) == 0 then open else openPrice[1]; def pctChangeFromOpen = (close - OpenPrice) / OpenPrice; AddLabel(yes, AsPercent(pctChangeFromOpen)); AssignPriceColor(if pctChangeFromOpen > 0 then color.green else color.red);

[@TOSIndicators]

Hi Kim - glad the video helped. It looks like you're missing the color parameter from the AddLabel code, which is what you can change to whatever color you would like. Example: AddLabel(yes, AsPercent(pctChangeFromOpen), if pctChangeFromOpen >= 0 then color.green else color.red);

[@KimYeoman]

Perfect! Thanks so much!

[@alkeshshah1777]

how we find change in open interest ?

[@TOSIndicators]

You'll need to create a separate custom quote, that tracks the open interest change over a specified strike.
