Show Bar Count when Volume > 1000

I read through your request a few times and still end up with two different ways to interpret your request. I believe you asking for one of these two:

1. For each trading session, display the number of bars since the first 1 minute bar recorded volume greater than 1,000
2. For each trading session, display the exact bar number at which the first 1 minute bar recorded volume greater than 1,000

Let me know which one it is. Or if you actually need something entirely different.

Since you are requesting a custom watchlist column and not a scan I have moved this out of the "Stock Scanners" topic and into the "Watch List" topic.

Edit: I can provide a solution now that we have clarification on this request in the comments section below.

The code will need to be run on a custom column that does NOT included extended trading hours. However it will also work if you included extended hours but it will begin the bar count after midnight Eastern.

input volumeThreshold = 1000;
def newDay = GetDay() <> GetDay()[1];
rec trackHighestVolume = if newDay then volume else if trackHighestVolume[1] < volumeThreshold and volume > trackHighestVolume[1] then volume else trackHighestVolume[1];
rec countBars = if newDay then 1 else if trackHighestVolume < volumeThreshold then countBars[1] + 1 else countBars[1];
plot data = if trackHighestVolume > volumeThreshold then countBars else 0;
data.AssignValueColor(if data <> 0 then Color.BLACK else Color.CURRENT);
AssignBackgroundColor(if data > 0 then Color.GRAY else Color.CURRENT);

Hi Pete, I wish I could show this to you in a screenshot but I'm unable to attach am image to the Comment. If you accept, I'm attaching a screenshot to the Solutions Only. 

But the problem is that the new watchlist column displays "1" all the the time. It does not display a number other than 1. It displays "1" even when the Option does not have a single volume bar greater than 1000. I looking for the column to display the first Bar Number which had volume > 1000. And the Options that I'm looking at have large volume and very liquid. Is that possible and am I doing something wrong?
