  • 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.
