First restart you Technical Analysis App & velocity. This will fill up the lost data automatically. If however, a gap has been created, the incremental data supplied would not be able to fill the gap.

To solve this, please backfill the data once. To do this ...

To Force Backfill (Amibroker) :


  • Right click on the Green Tab at the bottom right of Amibroker which says 'OK'
  • Click on Force Backfill (Velocity 1.0 / Amibroker eSignal plugin) - Historical Data is refreshed from locally available data in Velocity 2.0
  • Click on 'Backfill NIFTY' > 'Backfill All Data' (Velocity 2.0 - Amibroker ADK Plugin) - Historical data is refreshed from TrueData servers.
  • In Velocity 2.0 > If you however, need only today's data or a specific number of day's data use the desired option. There is no need to request for more data than you need as it will only take that much longer to download it & replace the already existing data.
  • Wait for a few seconds as the data is requested from the server (Entire EOD + 1 min data) & your charts updated again.

To Reload All Historical data (NinjaTrader7):


  • Right click on your chart & click 'Reload All Historical Data'
  • Wait for a few seconds as the data is requested from the server (Entire EOD + 1 min data) & your charts updated again.
  • Historical Data is refreshed from locally available data in Velocity 2.0. If you need to refresh the data from the servers, use 'Update from Feed'
