Auto data restore
From MultiCharts
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 based and minute based charts, the gaps are backfilled at once after the connection is restored.
“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'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;
- If there are any orders generated on the backfilled data and the auto trading is enabled - they are not sent to the broker.
