At opening of a new chart, the data are downloaded from the hard disk and the most last missing data are spooled from the trading server. If there are no history data available for the symbol on the hard disk, then the latest 512 bars of history will be downloaded. The price changes will be shown in the real-time mode. This information may stored in the history file and used at the reopening of this chart in future. You can use charts at offline also. Terminal allows working with offline charts.
