That is possible that during MultiCharts operation the Internet connection or the real-time data provider connection from your PC is lost. In such situation 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 on a next historical data request (copy/paste chart, close/open workspace).
“Backfilled at once” means that after physical connection recovery:
- Reconnection event is determined (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 regular way on the backfilled bars;
- The orders are generated and if the auto trading is enabled they are sent to broker.
