== Data Server Mode ==
Data Server Mode settings affect the whole software (MultiCharts, Portfolio Trader and QuoteManager). This page 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 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.# Select Check '''Download missing historical data''' to access download the missing historical data from a data provider server or it is limited to use only the data that is already stored in the database; 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 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 opened instances of MultiCharts, forward-testing and autotrading should be stopped in Portfolio Trader and QuoteManager should be closedexited, no [[Time and SalesForex_Board#Forex_Board_Service_Window|Forex Board service window]], should be dectivated and [[Understanding RealPre-Time Market ScannerScanning_and_Watchlist#Scanner_service_window|Service service Scanner]] or [[Dom|DOM]] window should be activatedcleared of all symbols (or also deactivated). </div>
To learn how this page affects data collected in MultiCharts, please read [[Collecting and Saving Data to MultiCharts Database|this article]].
Similar to this case if you enter with an order + auto attached stop loss and then you place another order in opposite direction with attached profit target, the position will be closed, but both stop loss order and profit target orders will stay active, because they are not bound to open position in this mode. </div>
:6. '''Price Order Emulation''' - since '''MultiCharts 12''' it is possible to switch between native and emulated Stop, Limit and Stop-Limit orders in both auto trading and manual trading. This feature requires realtime data subscription on your broker account. When a Stop/Limit order is emulated - once the Stop/Limit price level is reached by the corresponding Ask/Bid or Trade prices, a market /limit order is sent to the brokercorrespondingly. When a Stop-Limit order is emulated - once the Stop price level is reached by the corresponding Ask/Bid or Trade prices, a Limit order is sent to the broker. In case Stop, Limit and/or Stop-Limit order emulation is enabled - the emulated OCO group is used, disregard the broker profile/autotrading broker plugin settings.
To enable the Stop, Limit or Stop-Limit order emulation for manual trading select '''Emulate locally using Bid/Ask''' or '''Emulate locally using Trade''' from the dropdown list next to the corresponding order type. Leave the settings to '''Use native''' if using price order emulation is undesirable.
