- Split resource update.
- Removed native provider support for intraday scales that don't end on the hour and half hour marks; e.g., 13 or 78 minute bars.
- Scaling for these "odd" intervals will be performed by WealthLab using smaller intervals. We recommend deleting the IQFeed data folders for all "odd" intervals. See forum discussion starting from post #10 for more information.
- Split resource update - corrections to popular issues like MTCH, CPRT, INFY, ON. If in doubt, refresh intraday histories since some splits may have been applied twice.
- Show status messages during large data updates.
- Fixed volume for n-Second intervals; previously returned session cumulative volume.
- Fixed tick requests that were erroring out in some cases.
- Fix - tick charts adjusted for market time zone, previously always Eastern time.
- Fix - partial bars for markets that were not using Eastern Time.
- BarHistory returns with the correct MarketDetails.
- Data Providers are now more careful about checking Offline Mode before making web requests (requires WL8 Build 10+).
- Fixed partial bar initialization for streaming. Background: IQFeed changed the way it timestamped the partial bar. The WL8 IQFeed provider will handle both timestamp behaviors in case it changes again.
- The embedded resource used to split older intraday histories was overlooked in the migration to Verison 8. Refresh intraday histories for split adjustments.
- Initial WL8 release.
- Changed request method back to date range to avoid requesting bars that are not required.
- Skip unnecessary requests for expired futures contracts for which data is already cached if the contract expired more than 3 months ago (approximately).
- Changed method to request Daily bars to "Max Days" instead of using specific dates.
- Added a new IQFeed configuration option to enable parallel historical updates. Note: we had disabled parallel updates in IQFeed Build 10 due to excessive memory usage that could lead to crashes when updating large amounts of intraday data.
- Added documentation for using fundamental values available from IQFeed to the Help (F1).
- Added logic to create IQFutureSymbolSpecs.txt in the WealthLab7 User data folder. See Help for using these data.
- Changes to adapt to WL7 framework changes in Build 42.
- Fixed parsing error for specific records.
- Avoid requesting entire intraday history when a Max Bars Data Range is selected.
- Minor changes to take advantage of better data loading mechanisms in WL7 Build 37.
