• Handling of invalid data - determines the action taken in case of invalid data for a symbol
  • As warning - will display a warning message showing the first invalid bar, but will continue downloading data for the symbol
  • As error - will display an error message showing the first invalid bar, and will stop downloading the data for that symbol
• Volume 0 is invalid - if checked, a bar with volume 0 will be considered invalid (if price validation is on). The action (warning or error) will still be determined based on the pervious setting. If unchecked, a bar with volume 0 will be considered valid.
