We spent a good amount of time over the last week rectifying/cleaning the Wealth-Data DataSet. Thousands of changes were made - some are significant.
Although we haven't finished (Pass 2 will be next weekend), I recommend completely refreshing Wealth-Data now. You can save your current set of data by closing WealthLab and just renaming the WealthData folder in the User Data folder area. Then when you run your Strategies, the refresh will occur.

Rename
The second pass took more time than expected.
I strongly encourage everyone to completely refresh WealthData Historical (price) and Fundamental data at this time. Thousands of corrections were made.
Option 1 -
1. File > Open Wealth-Lab User Data folder
2. Close WealthLab.
3. Rename or delete the WealthData directory. Renaming the directory essentially backs up your old data.
Option 2 - (no backup)
1. Data Manager > Historical Providers
2. Right click > WealthData > Delete Local Files
3. Data Manager > Event Providers
4. Right click > WealthData > Delete Local Files
As always, data will be loaded by simply running a backtest. Alternatively, you can select each of the WealthData DataSets in the Data Manager and "Update DataSet".

I just ran a data integrity check on some WealthData ETFs and DIA is missing data for 11/21/2016. Can you confirm?
Thanks. That bar was lost but now has been found!
Found and added a few more missing bars.
Each of these were missing 1 bar: AAL, BFH, DDS, GHC, LUMN, MA, NC, SHEL
This one was missing 3 in October 2018: TTD

Once you have made the changes how do we update to reflect the fixes? I tried updating the data set but the missing date is still there. Do we need to follow one of the steps detailed in the earlier message to "reload" the data set?
You have to refresh. For just a few symbols, you can delete their files in the WealthData folder, or, open chart and Reload.
For now use "All Data" for the chart method. There might be a bug that reloads only the data in the chart's range.
