Data server mode selection provides flexibility for working with data feeds. This feature makes it possible to overcome limitations of some of the data feeds. If a data feed is available only on weekdays, the locally stored data can be used on weekends. If a data feed makes gap filling impractical by forcing a lengthy download of 24 hours of data for any intraday query, the gap filling feature can be disabled. | Data server mode selection provides flexibility for working with data feeds.

Two Data server modes are available: | |||
''' | '''Online''' – The locally stored data is used to for a historical chart. A check for gaps is not performed. Once the historical chart is completed, the real-time data will be received from a real-time data feed. Check '''Download missing historical data''' check box to perform a check for gaps and to fill any gaps found by connecting to a historical data feed. | ||
'''Offline''' – Only the locally stored data is used. No connections to data feeds are made. | |||
