How is this calculated? Is this on pace volume compare to amount time market has been open compard to avg 20 volume  How can this field be put into a scan as a codition to find stocks that are on pace to exceed avg20 day vol?   e.g.  100% at 11AM = vol = ading at avg 20 vol righnow

Should how is Volume Buzz calculated

A stock's volume for the current day (let's say at 11:32am) is compared to its average historical volume for the same percentage of the day. The volume buzz tells you how far ahead or behind the stock is based on its normal historical activity. A volume buzz of +250% means the stock is trading 250% more than normal for this portion of the day. A figure of -50% means the stock is trading at only half of its norm for this portion of the day. A figure of 0 means nothing unusual is going on in either direction.

Good morning all, 

I am joining this conversation to ask if a formula is possible. 

I would like to add a condition to a scanner wich calculate current day volume % compared to the 30 days volume mv.avg. 

Eg : Today volume represent less than 20% of the average volume of the last 30 days.

        Or today volume is between x% and x% of the average volume of the last 30 days.

Thanks a lot for your time worden team :) 

You can't do it in the same way Volume Buzz works and take into account the time of day, but you can write Personal Criteria Formulas which compare the volume of the day so far to average volume for full days over the previous 30 days.

100 * V / AVGV30.1

Checking for this to be less than 20% of average volume would be:

100 * V / AVGV30.1 < 20

Or the slightly shorter:

V < .2 * AVGV30.1

Checking for this to be between 30% and 50% of average volume could be written as follows.

30 <= 100 * V / AVGV30.1 AND 100 * V / AVGV30.1 <= 50

Or the slightly shorter:

.3 * AVGV30.1 <= V AND V <= .5 * AVGV30.1

Or the even shorter:

ABS(V / AVGV30.1 - 40) <= 10

Got it, perfect Bruce thank you so much ! 

100 * V / AVGV400.1 > 100

If i am think correct and you have this on a 60 minute bar, and 15 minutes into the bar it becomes true it would of course become true on the chart at that time and remain so until the next bar opened.

FOR STUDY PURPOSES IS THIER AWAY TO INCLUDE an addition to the PCF that will show that this became true in the 1st 15 mins of the bar, or 30 etc

So that you could review charts and see that the volume came in early

No, there isn't a way to do this. About the closest thing you could do is try to construct stuff in a 15 minute time frame instead of a 60 minute time frame. Then you could kind of manually go through the 15 minute time frame to see if it became true in the first 15 minutes.
