I'm buried in some end of the year paperwork right now, but let me offer a couple of quick comments.

1. The dropdown list of names is in the expanded version that I plan to put in the subscriber area along with some other functions related to portfolio mixes, such as percentage allocations, re-balance intervals, etc. My long-term intent is really to offer "starter" examples in the FREE CODE area that users can expand on. We want to concentrate on breadth of topics there.

2. One simple tip that might help deal with WL numbers in many places is to name your watchlist to their number plus that name. That will make the numbers easier to find in a long list of names in the watchlist tree. For example, my watchlist 13 is named "13 - Select".

3. Lastly, the ATC should be going into Group 253 since atcFlagDefaults was used in the ATC call in the example that I posted. I may have misread your note, but it seemed to say that you believe are seeing it in the watchlist. As far as what the ATC is named, you can use the name instead of the number by changing the AddtoComposite statement to the following -

AddToComposite( Lavg, "~ListAvg_" + CategoryGetName( categoryWatchlist, wlnum ),
"X", atcFlagDefaults + atcFlagEnableInIndicator );
