% Change through After Hours

[Tomahawk6117]

Hi Everyone,

I like the % change column that is already available for the scanner, however I do not believe this continues to update after hours. Is there anyway to provide a script that continues to update through 8:00 p.m.? I have attached a picture of the % change information I am referencing and highlighted it in yellow. Thank you very much for your time and your help.

def AMorPM = (if isnan(dif) then premarket else aftermarket);
AddLabel(yes, aspercent(AMorPM), if AMorPM >= 0 then color.green else color.red);

Thank you so much for your help @XeoNoX, I really appreciate it. Is this intended to only work after hours? Right now I am only showing 0% for all stocks. Also, does it matter which aggregation period I select? Thank you again for your help, I really appreciate it.

Based on your formula, you are trying to do exactly what I was requesting through subtracting the close of the current candle from the previous day's closing price. Thank you again for your help.

Hi @Joshua, do you have a script that would include all extended hours starting after yesterday's close? That is exactly what I am looking to use. Thank you very much.

it shows the difference in percent from the close of regular trading hours to the current close. if its showing 0 then its either 0 or you didnt follow the instructions.

Thank you very much @XeoNoX, is there any to calculate the %change from the previous day's close through 8:00 p.m. on the current day? For example, when I ran the scan for the stock, CREV, the script you provided says -3.31%, but from yesterday's close, the stock gained 41.82%. Is there anyway to calculate the 41.82%. Thank you very much for all of your time and your help.

if you want from yesterdays close, why didn't you say that in post #1?

I apologize, I should have been more specific. The current %change column in thinkorswim that is pre-built in calculates from yesterday's close. I just wanted to change the %change column so that it continues to run through 8:00 p.m. instead of stopping at 4:00 p.m. So overall, I would like a % change column to calculate from yesterday's closing price though today at 8:00 p.m. please. Thank you very much for all of your help.

correct, its shows -3.31% ... my script works as originally requested and as the title of the thread suggests (percent change after hours as a column), it shows the same on Google search, screenshot attached. if you are looking for something else maybe someone else can assist you.

I am new to ToS and to ThinkScript..
I am trying to learn but still need lots of help!
I was trying to create a Scan for Nasdaq Stocks less than 10 Usd PreMarket..
I used XeoNox Script as basis for PreMarket percent change..
I cannot get it to work..
I would attach the Script if I knew how to do it..
Any Help would be appreciated
