Overview

...

Spectra Adapter uses MOEX configuration file for getting information about feeds.

Currently, B2BITS FIX Antenna c++ support the following feed types:

...

languagexml
titleconfiguration.xml

...

Some configuration requires using of several sources of security definitions, e.g. ORDERS-LOG contains orders for both futures and options instruments. While working with ORDERS-LOG, MOEX Spectra Market Data Adapter should know security information for both security types. This article describes how to configure such option is described below

Customize feeds in Configuration file (configuration.xml)

How to set up multiple Security Definition feeds using configuration file 

Adding new connection

MOEX could provide separate configuration files for different feeds.

The configuration file could - configuration.xml could be extended with new connections if it requires.

For example, ORDERS-LOG connections connection can be integrated into an original configuration just by adding a new MarketDataGroup to configuration section:

Code Block
languagexml
titleconfiguration.xml
<configuration type="Test" label="Test System" marketId="MOEX">
<!-- ... -->
	<MarketDataGroup feedType="FUT-INFO" marketID="F" label="Futures defintion">
		<connections>
			<!-- FUT-INFO feeds -->
		</connections>
	</MarketDataGroup>



	<!-- New section with ORDERS-LOG connections -->
	<MarketDataGroup feedType="ORDERS-LOG" marketID="D" label="Full orders log">
		<connections>
            <!-- ORDERS-LOG feeds -->
		</connections>
	</MarketDataGroup>

</configuration>

...

Adding multiple

...

Security Definition sources

MarketDataGroup could may contain as many connections as it is required.

How to set up multiple Security Definition feeds using the source code

Extra security definition feeds could be configured with Spectra::SpectraApplicationParams::customSecDefFeeds_ parameter:

Code Block
languagecpp
titleApplication.cpp
Spectra::SpectraApplicationParams params;   
params.customSecDefFeeds_[Spectra::SpectraDataChannel("D", "ORDERS-LOG")].push_back(Spectra::SpectraDataChannel("F", "FUT-INFO"));   
params.customSecDefFeeds_[Spectra::SpectraDataChannel("D", "ORDERS-LOG")].push_back(Spectra::SpectraDataChannel("O", "OPT-INFO"));   
params.customSecDefFeeds_[Spectra::SpectraDataChannel("D", "ORDERS-LOG")].push_back(Spectra::SpectraDataChannel("S", "SPOT-INFO"));
Info
this approach This approach may be used as an alternative of configuration file (configuration.xml) modification and allows keeping the original version of configuration files.
