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.

Backfilling Availability. Data vendors list (realtime only/historical only data vendors are not listed):
