Thanks, Bruce.  That is exactly what I was reading.  Your explanation helps a lot.

Thank you, Michael.  That should start me off.  But this leads to a new question.  I'm trying to use this as the watchlist for an easy scan that compares 30-day price performance.  I'm looking at the pre-built "30-day performance vs. market" as my indicator.  I looked at the description of that in the help file and find myself confused.  

The description of the calculation shows an "X" and a "Y" that are not defined.  Do you have any clue as to what they are?

Thanks

How can I generate a watchlist of ETFs by country or region?  Also by sector?

How can I generate a custom indicator?  There are 2 indicators I would like to program as follows:

1. A "streak" RSI.  This would do a Wilder RSI calculation on a cumulative list of the number of bars which were higher than the last.  For instance, if a stock closed higher for 3 consecutive bars then was unchanged for 1 bar and finally went down for 2 bars, the list would be as follows: 1 2 3 0 -1 -2.  The number of bars to consider would be selectable.

2. A rank calculation.  Generate a list of bars as %change from previous bar.  Score each bar as

X/N, where X= # of bars < value of this bar, and N= # of bars to use.  N would be selectable.

Thanks for your help.

Thanks Bruce.

It was the copy issue that was the problem.  My original formula used 5000 for 500,000, not realizing that the old 100 share divisor was no longer used.  I didn&#39;t copy the change into the scan which is why, as you pointed out, it didn&#39;t work.

Thanks for the help.  However, this raises another question.  In order to change the ez-scan, I couldn&#39;t find a way to edit it and had to delete and rewrite it completely.  How does one edit a scan?

Thanks again.

Thanks for checking, Stockguy, but it doesn&#39;t give me the same result as you got.  I got 93 stocks with volume for the day as low as 3K.  Could there be something wrong with my local program?  I thought this was on the cloud so everyone would get the same result.  

I&#39;m confused.  Thanks for any additional help you can offer.

I&#39;ve created the following PCF and used it in a scan.  The scan results include many stocks with volumes well under 500,000.  Can you tell me what I&#39;m doing wrong?
