I need a formula that will allow me to compare the % increase in volume from the current trading day 

as it compares to the previous days total trading volume 

as an example 

If IBM traded 1,000,000 shares yesterday and today it traded 1,100,000 than volume increased 

10 %  but i need to be able to run this while the markets open 

so if at noon IBM traded 500,000 shares than the volume would be off 50 % from the previous days

total at that time as the day progressed the % will be changing 

thanks 

It is possible to create an Indicator Formula which will give the Volume Percent Change from the volume of the current bar to the volume of the current bar:

100 * (V / (V1 + .0000001) - 1)

But this will be based on the total volume of the previous bar and the current volume of the current bar.

There is no way to create an Indicator Formula which would compute this value based on the percentage of the current bar which has passed.

There is a Volume Buzz WatchList Column which can be added, but it compares the volume of the current day to 100-Day Simple Moving Average of Volume ending yesterday. It does take into account the percentage of the current day which has passed, but it will not work as anything other than a WatchList Column and cannot be re-creating using the Personal Criteria Formula Language.
