MamdaMsgListener
public class MamdaMultiParticipantManager extends java.lang.Object implements MamdaMsgListener
MamdaMultiParticipantManager is a class that manages updates on a consolidated basis for securities that may be traded on multiple exchanges and which may have a national best bid and offer. Developers are notified of each element available for the consolidated security, including the national best bid and offer, and each regional exchange (Market Maker). Developers can pick and choose which elements they wish to provide handling for (e.g., BBO-only, certain regional exchanges, etc.). Specialized Listeners can be added to theMamdaMultiParticipantManager
in response to the callbacks on theMamdaMultiParticipantHandler
being invoked. Alternatively, the Listeners can be added up front if the participants are known in advance. Note: theMamdaMultiParticipantManager
can also be used for securities that are not traded on multiple exchanges.
