==Saving Historical Data==
Most of supported data vendors provide historical data that is always stored locally after data is received. All types of data is are stored:
* Ticks, minutes, days (see [[Tick, Minute and Daily Data]]);
* Asks, bids, trades.
:* Minute and daily are recorded or not recorded for each data vendor individually:
:: <div style="background-color: #E3FBE5;">'''Note''': If a data source provides only real-time data (no historical backfill) it is always recorded in MultiCharts database. Only the data vendors, supporting both history and real-time feed are listed in the following table.</div>
