It's possible that during MultiCharts operation the Internet connection and/or connection to a real-time data provider from your PC is lost. In such situations the missing data can be backfilled by MultiCharts:

*On [[Tick, Minute and Daily Data|tick based]] charts, the gaps are backfilled at once after the connection is restored.

*On [[Tick, Minute and Daily Data|tick based and minute based]] charts, the gaps are backfilled at once after the connection is restored.

*On [[Tick, Minute and Daily Data|minute based]] charts, the gaps are not backfilled at once. The gaps are backfilled during a next historical data request (copy/paste chart, close/open workspace).

'''“Backfilled at once” means that after a physical connection recovery:'''

* A reconnection event is determined (a corresponding message appears in QuoteManager Event Log);

* Missing data is requested from the data vendor;

* Missing data is requested from the data vendor's historical data servers;

* Missing bars appear on the chart;

* Realtime bars appear after backfilled bars;

* The studies are not recalculated, they are calculated the regular way on the backfilled bars;

* ~~Orders~~ are generated and if auto trading is enabled they are sent to the broker.

* If there are any orders generated on the backfilled data and the auto trading is enabled - they are not sent to the broker.
