Premarket After-market For ThinkOrSwim

[XeoNoX]

@TheDakk if it doesnt work then that specific code just wont be compatible with the mobile version of thinkoswim, unfortunately some desktop thinkorswim scripts dont work on mobile as the mobile version has limitations, since the script uses current day and the nasdaq is closed, you may have to wait for a day when market is open and afterhours is active and then try again.

 

[TheDakk]

@XeoNoX Thanks, I'll check again on Tuesday and see if it works. Appreciate your help!

 

[TheDakk]

@XeoNoX Everything worked! The only thing I had a question about was

def today=getday()==getlastDay();

It looks like it's not even being called in that script? I removed the variable. I did make some minor tweaks to the time frame as well but ended up with these three columns for mobile:

AH Last

close

AH % Change

def close1 = if SecondsFromTime(0930) > 0 and SecondsFromTime(1600) < 0  then close else close1[1];
def change = (close / close1) - 1;
plot scan = round(change*100,2);
scan.AssignValueColor(if scan >= 0 then Color.UPTICK else Color.DOWNTICK);

AH Net Change

def close1 = if SecondsFromTime(0930) > 0 and SecondsFromTime(1600) < 0  then close else close1[1];
def change = close - close1;
plot scan = change;
scan.AssignValueColor(if scan >= 0 then Color.UPTICK else Color.DOWNTICK);

Also, doesn't like like colors work on custom quotes columns on mobile.

Premarket %change filter. Its no problem to filter % change in the normal hours. Is there anyway to filter the mark by % change in premarket? Seems like it would come in handy.

 

[XeoNoX]

@westsail5000 There are studies and threads in the forum that calculate the % change in premarket, aftermarket, regular hours. if you want the mark just change (CLOSE) to (((ASK-BID)/2) + BID) which will give you the mark that is typically the middle price of the bid and ask.

(((ASK-BID)/2) + BID)

@BenTen, Is it possible to plot Premarket open? Aside from the Premarket High and LOW I would like to add Premarket open as well. As Always, Thank You for your amazing work.

 

[BenTen]

@YAD Pre-market open? I don't know if there is a function for that.

 

[MColb]

Is there a way to scan for stock close to pre mkt highs before the open?

 

[XeoNoX]

Is there a way to scan for stock close to pre mkt highs before the open?

its built in to TOS, just choose near highs under price performance and make sure that you have ext hours checked.

After Market Hours Gainers

I know there is inbuilt After Market hours Scanner but I want to customize it 2% change in last 3 10 min bars data of after 4pm ET only to be considered. With addition filters I can add to this scan.

Also how do I add percentage change after market hours 4PM ET & volume after market hours 4PM ET columns to my watchlist.

Your help appreciated!

 

[XeoNoX]

@renz3 just change the aggregation to 30 minutes (3x10 min bars) and make it so that its 2% change.

 

[renz3]

Thanks @XeoNoX, Sorting does not work for the column also how can I use this new column in Scanner I don't see in Stock filter.

is there an easy way to see if premarket hours exist? for example HLYK has no premarket hours or aftermarket hours. it goes from 3:59pm yesterday to 9:30am this morning.

 

[bezaman]

i think i figured it out after a little testing. i will test some more...

def PreMktOpen = GetYYYYMMDD() != GetYYYYMMDD()[1];
def PreMktHrs = GetTime() < RegularTradingStart(GetYYYYMMDD());
def RegMktHrs = (GetTime() >= RegularTradingStart(GetYYYYMMDD())) and (GetTime() < RegularTradingEnd(GetYYYYMMDD()));

def pHigh = if PreMktOpen and PreMktHrs then high
            else if PreMktOpen and RegMktHrs then Double.NaN
            else if PreMktHrs and high > pHigh[1] then high
            else pHigh[1];

def pLow = if PreMktOpen and PreMktHrs then low
           else if PreMktOpen and RegMktHrs then Double.NaN
           else if PreMktHrs and low < pLow[1] then low
           else pLow[1];

Try this update to put a chart bubble on each line.

Thank you, exactly what I wanted. Midline a must.

 

[caspara2]

@theelderwand Thanks! This works great.

 

[s1111]

Is there a way to have Labels for PMH ,PMMid and PML with price ? I hate lines and clutters, it would be nice if someone can mod this script . Right now I'm using this code with show study off so I only see chartbubble.
Thanks in advance

It doesn't work for me, can someone please tell me what is wrong?

[rad14733]

@Xhrx The preferred method would be to use SecondsFromTime() and SecondsTillTime()...

def close1 = if SecondsFromTime(0930) >= 0 and SecondsTillTime(1600) > 0 then close else close[1];

 

[Xhrx]

I have a question, since the market is from 8:30 to 15:00 should I change that data on the script?

I have employed, now it display, however After Hour Change % is not precise:
QCOM Shows 0.0 Variation however the AH% change is -0.04%
On the same way BL doesn't show KFY doesn't show
Vuzi has the same error: Shows 0.68, however the AH% Change is 1.31%

What am I doing wrong @rad14733 ?

def close1 = if SecondsFromTime(0930) >= 0 and SecondsTillTime(1600) > 0  then close else close[1];
def change = (close / close1) - 1;
plot scan = round(change*100,2);
scan.AssignValueColor(if scan >= 0 then Color.UPTICK else Color.DOWNTICK);
