As I am working with Index Lab I am changing my data sets and getting everything organized. I find I need an easy way to tell WL to reload the data for all index calculations. I cannot find a way other than right-click->ReloadChartHistory. When I do a bad-data scan, I can create a list of bad symbols, stop WL, and delete the symbol files. Then I reload WL and update. This is much easier because I can write a script to delete the offending symbols. I tried this with a Index-Lab-Symbol.WL, and the system was very confused and thought the index was created but would not display it. How can I simplify the way to regenerate the data?

Do not stop WL. Find the folder with Index Manager's .WL files while WL is running, and delete the file to reload its data on next symbol data request.
