== Data Server Mode ===== Data server mode === Data Server Mode settings affect the whole software (MultiCharts, Portfolio Trader and QuoteManager). This page setting determines whether the software has access to real-time data from a data provider server or it is limited to use only the data that is already stored in the database.# Select '''Online: Load the locally stored data and connect to a real-time data feed''' to switch software to online mode and get access to data from data vendor servers.
# Check '''Download missing historical data''' to download the missing historical data from a data provider; clear the checkbox to work only with real-time data and locally stored data (no historical backfill from data vendor).
# Select '''Offline: Use only the locally stored data''' to work only with historical data that is already saved in the database. No additional data will be requested from the data provider in this case.# To show the '''Data Server Mode''' tab on software startup, select check the '''Show Data Server Mode dialog box on startup''' checkbox; clear the checkbox not to display the dialog box.
<div style="background-color: #E3FBE5;">'''Note''': In order to switch between the modes or turn on/off the "Download missing historical data" box, all workspaces should be closed in all instances of MultiCharts, forward-testing and autotrading should be stopped in Portfolio Trader and QuoteManager should be exited, [[Forex_Board#Forex_Board_Service_Window|Forex Board service window]] should be dectivated and [[Pre-Scanning_and_Watchlist#Scanner_service_window|service Scanner]] should be cleared of all symbols (or also deactivated). </div>

=== Currency conversion ===
Currency Conversion functionality is used for converting price values when Base/Preferred Currency is different from the symbol currency set in QuoteManager. Since MultiCharts 10 Release 3 an alternative currency conversion server can be selected.
The Currency Conversion settings are accessible from File -> Preferences -> Currency Conversion tab:
* Set '''Currency request timeout''' parameter to specify the time value for accessing the Currency Conversion Server. Select the value between 30 and 120 seconds. The default value is 30.
* Enable '''Allow calculation if Currency Conversion data is incomplete''' checkbox to retain auto-trading and calculate the signals with the previously received currency conversion data, in case Currency Conversion server cannot be accessed at that moment.
* Select the '''Data source''' that will be used for currency conversion from the drop-down list. Limited number of data feeds can be used efficiently for currency conversion (Interactive Brokers, LMAX, MCFX), as they provide continuous Daily Bid Forex historical data.
To use alternative currency conversion sources: Interactive Brokers, LMAX or MCFX, it’s required to have a subscription to the needed currency pairs with the selected data vendor.
If no alternative data feed is used, the Default currency conversion server can be chosen. It provides data for currency conversion since 2002.
<div style="background-color: #E5F6FF;"><u>'''NOTE'''</u>: MultiCharts needs to be restarted completely in order to apply any changes made for the Currency Conversion Server.</div>
'''Possible Issues'''
The message '''“Cannot access Currency Conversion server. Calculation will be stopped.”''' is displayed in case the Currency Conversion Server cannot be accessed within the specified timeout. This message indicates that the signal calculation will be stopped as there is no data for conversion. Therefore, the signal will be turned off and auto-trading will be disabled. To avoid this, check the box '''Allow calculation if Currency Conversion data is incomplete'''.
