Supported OMnet functionality for Trading

In the table below listed OMnet transactions which currently supported by OnixS EBS BrokerTec Handler:

OMnet transaction	Public API member that represents request	Public API member that represents response	Description
MQ8 [Total Order QUERY]	Sent automatically during snapshot	OnixS::BrokerTec::FirmOrderBookListener::onFirmOrderBookUpdate	This transaction is used for querying own orders in the Order Book or for another user in the same firm or for all orders for a firm.
MQ9 [Total Inactive Order QUERY]	Sent automatically during snapshot	OnixS::BrokerTec::FirmOrderBookListener::onFirmOrderBookUpdate	This transaction is used for querying own inactive orders in the Order Book.
MO31 [Order Entry TRANSACTION]	OnixS::BrokerTec::Handler::enterOrder	OnixS::BrokerTec::TradeListener::onEnterOrderAck or OnixS::BrokerTec::TradeListener::onEnterOrderFailed OnixS::BrokerTec::FirmOrderBookListener::onFirmOrderBookUpdate	This transaction is used for placing orders in the Order book.

MO40 [Inactive Deletion TRANSACTION]	OnixS::BrokerTec::Handler::cancelOrder OnixS::BrokerTec::Handler::cancelInactiveOrders	OnixS::BrokerTec::TradeListener::onCancelOrderAck or OnixS::BrokerTec::TradeListener::onCancelOrderFailed OnixS::BrokerTec::FirmOrderBookListener::onFirmOrderBookUpdate	The delete inactive transaction is used to remove one or more (by the matching engine) inactivated orders from the Order Book. This transaction can affect several orders at once - a group of orders to be deleted can be specified. This transaction is similar to MO4 but deletes inactive orders instead.
MO34 [Delete All User Order TRANSACTION]	OnixS::BrokerTec::Handler::cancelAllYourOwnOrders	OnixS::BrokerTec::TradeListener::onCancelOrderAck or OnixS::BrokerTec::TradeListener::onCancelOrderFailed OnixS::BrokerTec::FirmOrderBookListener::onFirmOrderBookUpdate	This transaction is used to remove all orders from a participant trader.
