It's possible that during a MultiCharts operation that 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 based charts, the gaps are backfilled at once after the connection is restored.
- On 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 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.
