Premarket After-market For ThinkOrSwim

Thanks @Len20 . I just added this watchlist column. It is showing the % change from the previous close not the % change after the market close.

Please check the ticker EVOK and it showing 2.6% and it is same as default % change column.

The formula would be Market % Change - % Change will be the correct value to identify the AH price change.

Here is another set of code found from Hahn site. I hope this okay to be shared here.

Code:
input marketClose = 1555;
def closeCounter = SecondsTillTime(marketClose);
def regSessEnd = closeCounter == 0;
rec priorDayClose = if regSessEnd then close else priorDayClose[1];
def change = ((close-priorDayClose) / priorDayClose) * 100;
def con1 = change >= 3 or change <= -3;
plot scan = con1;

@lowtrade It sounds like you have the aggregation period set to daily. It needs to be set lower. 1 min aggregation should be accurate and shows EVOK at 74.5%. I use 1 hr aggregation because it seems to load slightly faster and I believe it is just as accurate.

The only difference from code that uses daily aggregation is the final closing price for the day might actually be slightly different than the close of the final bar for that day.

Hi, does anyone have an issue with this code where gXhigh goes N/A at 10:45am? It's happening to me repeatedly and is repeatable using OnDemand. I'm trying to debug it but I'm not as familiar with thinkscript. @BenTen
 
Hi Ben! First time here. Could this be changed to show only high and low of premarket session, that starts at 4 AM EST? with the option to show only last day or all. Thank you!!
 
@thinky See code above
Hey, @BenTen, I also would like to see fib lines based on the high and low of premarket. You told Thinky to look above, but I tried the two above, yet neither of those were fib drawings based solely on the PM high and lows. Is it possible somebody modified the code after you had posted this?

Thanks,
Jason
 
@CDJay The code in post #1 will do exactly just that. Did you try it out yet? Can you show a screenshot of what is not working?
 
@BenTen

A couple of questions:

Question #1. How can I remove the colored price bubbles on the right side?

I don't know which lines in the code I need to modify.

I am using your code from #1 (Page 1).

Question #2. How can I change the color of the Fibonacci lines? I couldn't find any color indications for the Fibo lines in the code.

Thank you

@twitty_twit You can disable the bubbles by opening the Study Settings Panel, the gear at the right of the Study, and Un-Check the Show Bubble option... I turn them off on most Studies and most Studies have multiple bubbles to turn off...
 
Hello,

I found this indicator but it only plots on the current day. I want every day to have the overnight high and low plotted. Is there some modification I can make to the code so that it shows the levels for all days?
 
@Esminiguu Did you try the code in post #3? If that doesn't work then use the code below:

Code:
# TS_GlobexRange
# http://thinkscripter.wordpress.com
# [email protected]
# Last Update 18 JUL 2009

input Globex_Open = 1630;
input Globex_Close = 0930;

def globexOpen = if(secondsFromTime(Globex_Open) >= 0 or secondsTillTime(Globex_Close)>=0, 1, 0);
def globexReset = if globexOpen and !globexOpen[1] then 1 else 0;

rec globexHigh = compoundValue(1, if((high > globexHigh[1] and globexOpen) or globexReset, high,globexHigh[1]),high);
rec globexLow = compoundValue(1, if((low < globexLow[1] and globexOpen) or globexReset, low,globexLow[1]),low);

plot Globex_High = globexHigh;
Globex_high.SetStyle(curve.SHORT_DASH);
Globex_High.SetDefaultColor(color.pink);
Globex_High.setLineWeight(2);
plot Globex_Low = globexLow;
Globex_Low.SetDefaultColor(color.pink);
Globex_Low.setLineWeight(2);
 
@korygill Nice work on this!!

Is it possible to set this up so it would show previous premarket price channels as well? I've got another set of lines I want to merge with this but keep coming up empty on being able to see the premarket channel for previous days.
 
Here is an update to track prev values like that @autolox asked for.

Does anyone have a scanner that will alert you when a stock breaks above PM highs and break below PM lows? I have been searching through this site and cant seem to find one. Thanks!
 
@lowtrade is correct your scan and the default TOS study for After hours percent change are incorrect they are showing the change from previous day close. How to scan for the difference between Last and Mark? The formula should be (Mark-Last)/Last. For CRIS today the % it gained in the after hours only should be (6.86-6.55)/6.55 = .047%

go back and read the first or second page of this thread. BenTen lays it out for you.
 
@BenTen

I am using your code from #3 of this thread.

Currently, the automatically drawn pre-market high and low lines only show on today's date. I would like to see it for previous days for the last 10 days.

What parts of the code need to be added or changed?

Thank you
 
@ojtrade You can try this one:

Code:
# TS_GlobexRange
# http://thinkscripter.wordpress.com
# [email protected]
# Last Update 18 JUL 2009

input Globex_Open = 1630;
input Globex_Close = 0930;

def globexOpen = if(secondsFromTime(Globex_Open) >= 0 or secondsTillTime(Globex_Close)>=0, 1, 0);
def globexReset = if globexOpen and !globexOpen[1] then 1 else 0;

rec globexHigh = compoundValue(1, if((high > globexHigh[1] and globexOpen) or globexReset, high,globexHigh[1]),high);
rec globexLow = compoundValue(1, if((low < globexLow[1] and globexOpen) or globexReset, low,globexLow[1]),low);

plot Globex_High = globexHigh;
Globex_high.SetStyle(curve.SHORT_DASH);
Globex_High.SetDefaultColor(color.pink);
Globex_High.setLineWeight(2);
plot Globex_Low = globexLow;
Globex_Low.SetDefaultColor(color.pink);
Globex_Low.setLineWeight(2);
 
Has anyone finally solved this? Is their a functional code that incorporates the latest comments?

Would be most obliged if someone can post😇🙇‍♀️❤️🙏
