Syntax

events = createOrderAndRoute(c,order)
events = createOrderAndRoute(c,order,'timeOut',timeout)
createOrderAndRoute(___,'useDefaultEventHandler',false)
___ = createOrderAndRoute(c,order,options)

Description

events = createOrderAndRoute(c,order) creates and routes a Bloomberg® EMSX order using Bloomberg EMSX connection c and order request order. createOrderAndRoute returns the order sequence number, route number, and status message using the default event handler.

example

events = createOrderAndRoute(c,order,'timeOut',timeout) specifies a timeout value timeout for the execution of the default event handler.

example

createOrderAndRoute(___,'useDefaultEventHandler',false) creates and routes a Bloomberg EMSX order using any of the input arguments in the previous syntaxes and a custom event handler. Write a custom event handler to process the events associated with creating and routing orders. This syntax does not have an output argument because the custom event handler processes the contents of the event queue. If you want to use the default event handler instead, set the flag 'useDefaultEventHandler' to true and use the events output argument. By default, the flag 'useDefaultEventHandler' is set to true.

example

___ = createOrderAndRoute(c,order,options) uses the options structure to customize the output, which is useful to preconfigure and save your options for repeated use. The available options structure fields are timeOut and useDefaultEventHandler. Use the events output argument when useDefaultEventHandler is set to true and omit this output argument when useDefaultEventHandler is set to false.

To create and route a Bloomberg EMSX order, create the connection c using emsx and set up the order and route subscription using orders and routes. For an example showing these activities, see Manage Bloomberg EMSX Order and Route.

Create the order request structure order to define the order parameters. This code creates a buy market order for 100 shares of IBM®. This code uses the broker BB with the time in force set to DAY and any hand instruction. Convert the number of shares to a 32-bit signed integer using int32.

order.EMSX_TICKER = 'IBM';
order.EMSX_AMOUNT = int32(100);
order.EMSX_ORDER_TYPE = 'MKT';
order.EMSX_BROKER = 'BB';
order.EMSX_TIF = 'DAY';
order.EMSX_HAND_INSTRUCTION = 'ANY';
order.EMSX_SIDE = 'BUY';

Create and route the order using the Bloomberg EMSX connection c and order.

events = createOrderAndRoute(c,order)
events = 
    
    EMSX_SEQUENCE: 335877
    EMSX_ROUTE_ID: 1
          MESSAGE: 'Order created and routed'

The default event handler processes the events associated with creating and routing the order. createOrderAndRoute returns events as a structure that contains these fields:

  • Bloomberg EMSX order number

  • Bloomberg EMSX route identifier

  • Bloomberg EMSX message

Unsubscribe from order and route events using the Bloomberg EMSX subscription list objects osubs and rsubs. This code assumes that orders creates osubs and routes creates rsubs.

c.Session.unsubscribe(osubs)
c.Session.unsubscribe(rsubs)

Close the Bloomberg EMSX connection.

Create and route the order using the Bloomberg EMSX connection c and order. Set the timeout value to 200 milliseconds.

events = createOrderAndRoute(c,order,'timeOut',200)

Suppose you create a custom event handler function called eventhandler with input argument c. Run eventhandler using timer. Start the timer to run eventhandler immediately using start. For details, see Writing and Running Custom Event Handler Functions.

t = timer('TimerFcn',{@c.eventhandler},'Period',1,...
          'ExecutionMode','fixedRate')
start(t)

t is the MATLAB® timer object. For details, see timer.

Create and route the order using the Bloomberg EMSX connection c and order. Set the flag 'useDefaultEventHandler' to false so that eventhandler processes the events associated with creating and routing an order.

createOrderAndRoute(c,order,'useDefaultEventHandler',false)

Unsubscribe from order and route events using the Bloomberg EMSX subscription list objects osubs and rsubs. This code assumes that orders creates osubs and routes creates rsubs. Stop the timer to stop data updates using stop.

c.Session.unsubscribe(osubs)
c.Session.unsubscribe(rsubs)
stop(t)

If you are done processing data updates, delete the timer using delete.

delete(t)

Close the Bloomberg EMSX connection.
