There is are plenty of ways to recieve receive data in MultiCharts, however each way treats received data individuallydifferently. The only thing in common thing is that no data can be received (except for ASCII Import, see) if Multichart's Offline mode of MultiCharts Mode is selected.<div style="background-color: #E3FBE5;">'''Note''': Data that was recieved received in MultiCharts is stored in a cache during MC 's working session. Once the software ('''tsserver.exe''', see [[MultiCharts Processes]]) is shut downshutdown, the data is saved into the MultiCharts database. </div>
==Saving Historical Data==
Most of supported data vendors provide historical data that is always stored locally after data is received. All types of data are stored:
* Ticks, minutes, days (see [[Tick, Minute and Daily Data]]);
* Asks, bids, trades.
<div style="background-color: #E3FBE5;">'''Exceptions''': Historical data from the following data sources is not stored locally:<br>* [[ASCII Mapping]]<br>* [[CSI]]<br>* Historical data from [[GlobalServer]] can be stored locally if the box is checked in the data source settings.<br>* [[MetaStock]]<br>* Historical data from [[TradeStation]] can be stored locally if the box is checked in the data source settings.</div>
When data is imported from an ASCII file, it is always stored in the MultiCharts database.
==Saving Collected in Real-Time Data==
===Saving RT Data Collected in QuoteManager===
All types of data received from data vendors , if "Collect RT Data w/o Plotting" is on in QuoteManager , (see [[Online Mode Data Collection]]) is are stored in the database.
===Saving RT Data Collected in MultiCharts===
* RT data plotted in the DOM window is not saved.* RT data plotted in the Market Scanner window is saved the same way as data plotted in Chart window.* RT data plotted in the Time & Sales Window is saved the same way as data plotted in Chart window.* RT data plotted in the Chart window is stored or is not stored, depending on its type:
:* Ticks are always stored.
:* Minute and daily data 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 the MultiCharts database. Only the data vendors, supporting both history and real-time feed feeds, are listed in the following table.</div>

<b><font color="green">V</font><font color="red">*!</font></b> - The Open E Cry data source provides real-time minute data that is stored in a database. It is important to know that if charts only with minute data from Open E Cry are plotted in MultiCharts, tick data is not stored locally.
<div style="background-color: #E3FBE5;">'''Note''': Take into account that the '''Download Missing Historical Data''' checkbox affects the way MultiCharts treats received real-time data for Chart and Market Scanner windows. </div>
<div style="background-color: #E3FBE5;">'''Note 2''': If a data vendor does not provide historical Ask/Bid data, than Ask/Bid data received in real-time is recorded in the MultiCharts database. </div>
