Premarket Volume For ThinkOrSwim

[Gboyega]

No need to apologize, you don't owe anybody anything bud. And thank you for sharing!

Premarket RVOL, exactly what I was looking for! We're obviously looking for stocks with volume in the morning.

EDIT: I made a scanner and watchlist column based on your code.

Add this as a study: http://tos.mx/NvAn3MK (or use code below). Click here for --> Easiest way to load shared links

#Use 30min timeframe

Declare Lower;
Declare zerobase;
def Day0PMVol = If getday() <> GetDay()[1] then If SecondsFromTime(0930) < 0 then volume else 0 else If secondsFromTime(0400) >= 0 and SecondsFromTime(0930) < 0 then Volume+Day0PMVol[1] else Day0PMVol[1];

def pmvolplotted = If secondsFromTime(0400) >= 0 and SecondsFromTime(0930) < 0 then Day0PMVol else Double.nan;

Def PmBack1Day = If GetDay() <> GetDay()[1] then Day0PMVol[1] else PmBack1Day[1];
Def PMBack2Day = If GetDay() <> GetDay()[1] then PmBack1Day[1] else PmBack2Day[1];
Def PmBack3Day = If GetDay() <> GetDay()[1] then PmBack2Day[1] else PmBack3Day[1];
Def PMBack4Day = If GetDay() <> GetDay()[1] then PmBack3Day[1] else PmBack4Day[1];
Def PmBack5Day = If GetDay() <> GetDay()[1] then PmBack4Day[1] else PmBack5Day[1];
Def PMBack6Day = If GetDay() <> GetDay()[1] then PmBack5Day[1] else PmBack6Day[1];
Def PmBack7Day = If GetDay() <> GetDay()[1] then PmBack6Day[1] else PmBack7Day[1];
Def PMBack8Day = If GetDay() <> GetDay()[1] then PmBack7Day[1] else PmBack8Day[1];
Def PmBack9Day = If GetDay() <> GetDay()[1] then PmBack8Day[1] else PmBack9Day[1];
Def PMBack10Day = If GetDay() <> GetDay()[1] then PmBack9Day[1] else PmBack10Day[1];

Def PMAvgVol = (PmBack1Day + PmBack2Day +  PmBack3Day + PmBack4Day + PmBack5Day + PmBack6Day + PmBack7Day + PmBack8Day + PmBack9Day + PmBack10Day)/10;

plot PMRVOL = Day0PMVol/PmAvgVol*100;

And this as a watchlist column: http://tos.mx/fkbbmK5 (or use code below).

plot PMRVOL = Day0PMVol/PmAvgVol*100;

Set both to 30min timeframe. Then scan the study (the first code) with, for example >100 (for greater than 100%), or like so:
PM_RVOL() is greater than 100
The bold part is the default name of the study, so if you rename it, you will need to change that to whatever you named it.

Hi,
I included the PM_RVOL in my watchlist but some of the figures are not showing. just getting

Nan or "custom expression subscription limit exceeded"

can someone assist me please

Watchlist Column "custom expression subscription limit exceeded"
TDA purposely throttles any of your scripts that require a high use of TDA resources:

Nan is a mathematical error. There is no premarket vol to display

It's also my understanding that there is a limit to how many custom expressions you can display at once too, so having too many tickers showing using a bunch of custom watchlist columns will have the same effect.

Does this need to be scanned only during pre-market? or can I run this can even after 930?

You can run it at any point through the day, but like @stormy77 said, there is a limit as to how much code you can use in headers, custom scans, conditional orders, etc.. Studies and Strategies do not have a limit, but they will give you a warning that data may be delayed.

Maybe, but why would you? The numbers themselves won't mean anything.

Head this way for RVOL during the day!
