I want to create an indicator that plots the sum of the up volume for a give bar minus the sum of the down volume for a given bar for all the stocks in the Optionable Items watchlist. I use one-minute charts and only want to sum up the volume for each bar (and not the volume so far for the day). For a bar to be up, its close must be higer than the close one minute ago, and for a down bar, the close must be lower than the close one minute ago.
Thank you.

You can Plot an Average by right-clicking on the following RealCode Indicator and selecting Create Custom Index | Optionable Items | Next | All Stocks in WatchList | Next | Finish.
Dim Output As Single = 0
If Price.Last > Price.Last(1) Then
Output += Volume.Value
Else If Price.Last < Price.Last(1) Then
Output -= Volume.Value
End If
Plot = Output
If you really need it to be a sum, you would need to know how many items are in the WatchList (currently 3195) to use in the RealCode.
Dim Output As Single = 0
If Price.Last > Price.Last(1) Then
Output += Volume.Value
Else If Price.Last < Price.Last(1) Then
Output -= Volume.Value
End If
Plot = 3195 * Output

Bruce,
Thank you for the indicator. I followed the instructions to Create Custom Index but did not have success. I was able to go to Add Indicator | Create in RealCode | New RealCode Indicator (which gave me the name My Indicator in the Name box | and then pasted the code here.
Will this way work too because I seemed to get a graph?
Also, would you be able to help me with a second indicator. Using the same list of Optionable Items, I want to create a customized TRIN (#Advancing Issues / #Declining Issues) / (Volume of Advancing Issues / Volume of Declining Issues) where the close of each bar during the day is compared with the close of the previous intraday bar (as compared with the closing price for yesterday) and the data used in the calculation of the TRIN comes only from the most recent bar. For instance, a stock is advancing if the close is higher than the close one minute ago. In this case, this advancing issue is added to the sum of all of the advancing issues for this bar and the volume is added to the total of all the advancing volume for this bar (and the same logic applies to declining issues.)
Thank you.
Scott

The RealCode Indicator will produce a graph. The results are for that symbol. You need to create a Custom Index out of it to get results for the WatchList as a whole. What is happening? Are you getting error messages when you right-click on the RealCode Indicator and follow the directions for converting it into a Custom Index?
It's rather slow, but you should be able to Open the attached Chart directly into a running copy of StockFinder.Attachments:

Bruce,
Thank you for the Arms Index. I was able to open the chart using the posted link.
The indicator could not keep up on the one-minute chart during the trading day. If I switch to a 15-minute chart, can I set the Refresh Rate (under Edit Arms Index) to 5 minutes or do I need to keep the Refresh Rate the same as the interval of my chart? If I update every 5 minutes and my bar interval is set to 15 minutes, are the results based on calculations made on data generated by the bar up to that point in time (i.e. when only 10 minutes have passed in a 15-minute bar)? Also, I was watching the volume for the symbols uder Main WatchList. Does the volume get reset to zero at the end of every bar?
Thanks again for your help.
Scott

You can have a different reset rate for your WatchList than the Time Frame of your Chart.

It is going to use the most recent data available at the time of the calculation.

I'm not entirely sure what is meant by the question, but the Volume of a Bar in the Volume Bars Indicator is based on the Volume of just that Bar.
