Each transaction has an event type. An event type specifies the business intent of the transaction. Event types are used in the context of a transaction message type, such as MTOPEN (open transaction), MTCLOSE (close transaction), MTLINK, and MTCASH.

Content on this page:

  • BUY. Opens a long position. Can be used to open equities, options, caps, floors, rights, warrants, and all debt.

MTLINK Events

MTLLINK event types include:

  • JNLCVR. Nets a long and short position to one net long or short position. The MTLINK event creates an MTCLOSE JNLCVR LONG loopback which then spawns an MTCLOSE JNLCVR SHORT event.
  • SPOT. Used to create a currency contract which usually settles in just a few days from trade date. No cost is recorded. The MTLINK event generates two MTCASH SPOT events, one being a disbursement for the currency sold and the other a receipt for the currency purchased.
  • TRADEFWD. Used to create a currency contract which usually settles on some future date. No cash record is created at the time of the trade but rather when either the contract is closed or when it matures. The MTLINK event generates either an MTCLOSE TRADEFWD LONG or MTOPEN TRADEFWD SHORT event for the non-settle leg first depending on the close eligible flag (tag 3924) and whether or not the currency being sold is the non-settle leg. If tag 3924 is N and the currency being sold is the non-settle leg, an MTOPEN TRADEFWD SHORT event is created. The non-settle event then generates the settle leg loopback event.
