I want to delete the symbol data (historical) that WL8 stores. How to do it?
I am writing a custom C# historical data provider that uses WL8 persisted storage.
While writing the code, I needed to test it, so I was returning only the last 30 daily days. Now that the testing is done, I want to provide older data. When I use the "Reload data from the provider" option in the WL8 interface, it always queries for only 30 days, which I used to provide during testing.
I want to delete the persisted data so that WL8 queries from the beginning of time or otherwise somehow make it query older data. How should I do it?

Rename
Data Manager > Historical Providers tab > highlight a provider, choose "Delete Local Files" and "Clear tracking..."
QUOTE:Just request a chart whose Start Date is the earlier start date you want. If the data is before the cached data, WL will request it.

The default data range for new charts comes from Preferences > Data
I dont see "Delete local files" or "Clear tracking"
You don't need to do that (if you don't want to). See Post #2.
But if you do want to do do it, right click the Provider whose data you want to delete.

Note: you need to Right Click on the provider to see these options in the popup menu.
The "Delete Local Files" option is only available if the Historical Provider supports persistent storage (UsesPersistentStorage returned true) and it is configured.
The "Clear Tracking Info" option should be available for all Providers, are you sure it's not enabled?

I have "500 bars" in my Preferences -> Data. Still, WL only queries 30 daily bars for this specific symbol, which I used for testing. I know that WL8 will query older data for other symbols (that I have not used in the testing)
The right-click option worked. Thanks
