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:

  • 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.
