Overview

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

Currently, B2BITS FIX Antenna C++ supports the following feed types:

Code Block
languagexml
titleconfiguration.xml
<type>Incremental</type>
<type>Snapshot</type>
<type>Instrument Incremental</type>
<type>Instrument Replay</type>

Some configuration requires using of several sources of security definitions. Please use instructions below for configuration of , 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.

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 This approach could may be used as an alternative of configuration file (configuration.xml) modification and allows keeping the original version of configuration files.






How to get MDEntryTime with

nanosecond precision.

move to "How to" for MOEX Spectra MD Adapter 


MOEX Spectra uses Market Data Multicast FIX/FAST Platform uses custom UTCTimeOnly, UTCTimestamp format in the FAST messages.

Find more details in official documentation: http://ftp.moex.com/pub/FAST/Spectra e.g. http://ftp.moex.com/pub/FAST/Spectra/docs/spectra_fastgate_en.pdf

MOEX Spectra Market Data Adapter handles this format in the following way: TBD

Example:

Code Block
languagecpp
titleApplication.cpp
collapsetrue
void ConvertTimeToStr(System::u64 entry, std::string* strTime)
{
    static std::size_t const TIME_LENGTH = sizeof( "HHMMSSsssssssss" ) - 1;

    std::stringstream stream;
    stream << entry; // convert u64 to std::string.
    std::string time(stream.str());
    if (TIME_LENGTH > time.size())
        time.insert(0, TIME_LENGTH - time.size(), '0');

    strTime->assign(time, 0, 2); // HH
    strTime->append( ":");
    strTime->append(time, 2, 2); // MM
    strTime->append( ":");
    strTime->append(time, 4, 2); // SS
    strTime->append( ".");
    strTime->append(time, 6, 9); // sssssssss
}


bool InstrumentHandler::onIncrement( Spectra::SpectraSubscriptionItem const& subsItem, Engine::FIXMessage const* const* msgs, size_t incrementsCount )
{
	// ...
    for( ; i < incrementsCount; ++i ) {
	    const Engine::FIXGroup& gr = msgs[i].getAsGroup( FIXFields::NoMDEntries );
	    for( int j = 0; j < gr.size(); ++j ) {
		    const Engine::TagValue& entry = *gr.getEntry(j);
			std::string timeNs;
			if (entry.hasValue(FIXFields::MDEntryTime))
				ConvertTimeToStr(entry.getAsUInt64(FIXFields::MDEntryTime), &timeNs);
			// ..
		}
	}	
	// ...
