Since foreign stocks are supposed to be doing pretty good lately, I've put together several American Depositary Receipt stock lists, one a list of 250 symbols and one a list of about 371 symbols. These are daily data collected from Fidelity updates.

When I try to run various canned strategies on them, about halfway through, the strategies freeze up with similar messages:

QUOTE:
Runtime Error: Cannot convert 212506928 Bars to Daily Scale
at WealthLabPro.ChartForm.n()
at WealthLab.BarsLoader.Get (Data source ds.string symbol)
at WealthLab.BarScaleConverter.ToDailyBars(sb)

The run Strategy freezes midway, showing it "collecting data" on a symbol. So I delete that symbol, and it freezes on the next symbol. So I delete the next symbol and it freezes on the next symbol, .... etc.

Since I set up the data set as for daily bars, why should it need to try to convert any data to Daily Scale?

I understand many if not most or all ADR symbols may not have as complete information as to fundamental data, but I tried running several different strategies, and they all choked similarly.

Any ideas what might be going on?

Thanks. Below is a list of 250 ADRs:

Let's isolate the problem.

1. It appears you have on demand updates on. Please turn them off in the Data Manager tool, then see how it goes.
2. Next, which bundled Strategy can help us reproduce the issue.
3. Then, double check that the basis scale is really daily - for it looks the dataset could be intraday.
4. Finally, take a look in Preferences-Advanced Settings: is the Data Scale checkbox enabled?

1. Demand updates is off and was off.
2. Darvas Box; Two Bar Breakout; 3x2 System; Head and Shoulder Top; A Seven Liner; NeoMaster; DipBuyer; T2 Trend Friend; etc.
3. In Data Manager, under the Scale heading all of my data sets say "Daily" (I do not and have not use intraday data or do intraday strategies).
4. No, Data Scale checkbox is not enabled in Preferences-Advanced Settings.

Thank you. Using WLP 5.4, so far I was unable to reproduce the problem using different data loading settings with the strategies specified. More than 100 of these symbols have no data at all (assuming Fidelity data), so you may want to rule them out anyway. Also try deleting the existing data and reloading them again (Data Manager, "Delete data for symbols that are not contained in datasets").

I am still using WLP 5.3.

I have already done the delete data and reloaded the data, to no avail.

From Data Mgr / Fidelity Data / Action / Delete Symbols / I've deleted the null symbols and they are no longer in that list. ... However, after exiting WLP 5.3 and reloading WLP 5.3, I see that my Data Set still has the same count of symbols. I thought this process would have removed such null symbols from my Data Sets as noted in the sidebar? Maybe I need to do an update symbols to refresh them? It takes between one hour to over two hours to update my symbol lists of between 3 to 4 thousand, so I usually wait til 2 pm PST before doing so.

Tried to upgrade to WLP 5.4, but system replied Installed Version of Wealth Lab (5.3) is current.

Re WLP 5.4: it's not yet released, I just couldn't reproduce the issue with a pre-release build.

Re: deleting null symbols -- did you hit the "Apply" button on the DataSet?

Please create a support ticket for tracking purposes, linking to this thread.

I completed running an update on the data sets (59 minutes). Of course being end of day sets, much as to price does not require updates, but there may have been other data to be updated.

Having already "deleted" the bad symbols, now, checking the bad symbol list, nothing is listed as bad (previously there were quite a few). However, there are still the same number of symbols in the ADR sets.

Since you said about 100 or so of the 250 ADR list are null value, is there some other way to generate a list of which symbols are of null value, for manual deletion from the Data Sets?

I do not see any "Apply" button on the DataSet at this time. I do not recall hitting any "apply" button earlier. I did have "Symbol Mgmt" turned on, and do recall hitting "Delete Symbols" which says "Deletes the data from these symbols and removes them from the data sets."

Will create support ticket for this. Thanks for your help.

I'm not talking about Fidelity Symbol Management, rather the unified operation of modifying a DataSet. Please see the WL User Guide, Data > Data Manager > How to: Add Symbols or Modify a DataSet.

In the Data Manager tool, highlight the ADR DataSet and click "Symbol Details". Sort the list by Bars.

Pretty easy. In the Strategy code, check if the symbol has its bar count greater than 0 and print the symbol name to debug (or file). Run it in MSB mode, thereby collecting only the valid symbols. Copy and paste the list into a new DataSet and ditch the old one. Voila, your done.

Well, I weeded out the null symbols as you suggested.

Now everything is working fine; the ADR data sets do run.

Thanks, I'll be cancelling the support ticket.
