Syntax

events = routeOrderWithStrat(c,route,strat)
events = routeOrderWithStrat(c,route,strat,'timeOut',timeout)
routeOrderWithStrat(___,'useDefaultEventHandler',false)
___ = routeOrderWithStrat(c,route,strat,options)

Description

events = routeOrderWithStrat(c,route,strat) routes a Bloomberg® EMSX order with strategies using the Bloomberg EMSX connection c with the Bloomberg EMSX C++ interface, route request route, and strategy strat. routeOrderWithStrat returns the order sequence number, route number, and status message using the default event handler.

example

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

example

routeOrderWithStrat(___,'useDefaultEventHandler',false) routes a Bloomberg EMSX order with strategies 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 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

___ = routeOrderWithStrat(c,route,strat,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 the flag useDefaultEventHandler is set to true and omit this output argument when useDefaultEventHandler is set to false.

To route a Bloomberg EMSX order with strategies, create the connection c using emsx, set up the order subscription using orders, and create the order using createOrder. For an example showing these activities, see Create and Manage Bloomberg EMSX Order Using Bloomberg EMSX C++ Interface. Set up the route subscription using routes.

Define the route request structure route. Convert the numbers to 32-bit signed integers using int32. This code specifies to route 100 shares of IBM® to the broker BMTB using any hand instruction and the order number 335877.

route.EMSX_SEQUENCE = int32(335877);
route.EMSX_TICKER = 'IBM';
route.EMSX_AMOUNT = int32(100);
route.EMSX_BROKER = 'BMTB';
route.EMSX_HAND_INSTRUCTION = 'ANY';

Create the order strategies structure strat using the strategy SSP. Convert the field indicators to a 32-bit signed integer using int32.

strat.EMSX_STRATEGY_NAME = 'SSP';
strat.EMSX_STRATEGY_FIELD_INDICATORS = int32([0 0 0]);
strat.EMSX_STRATEGY_FIELDS = {'09:30:00','14:30:00',50};

Route the order using the Bloomberg EMSX connection c, route, and strat.

events = routeOrderWithStrat(c,route,strat)
events = 
 
     EMSX_SEQUENCE: 335877
     EMSX_ROUTE_ID: 1
           MESSAGE: 'Order Routed'

The default event handler processes the events associated with routing the order. routeOrderWithStrat 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.

strat.EMSX_STRATEGY_FIELDS = {'09:30:00','14:30:00',50};

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

events = routeOrderWithStrat(c,route,strat,'timeOut',200)
events =

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.

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

routeOrderWithStrat(c,route,strat,'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.

Convert the numbers to 32-bit signed integers using int32. EMSX_SEQUENCE must denote an existing order sequence number.

Field

Description

EMSX_SEQUENCE

Bloomberg EMSX order sequence number

EMSX_TICKER

Bloomberg EMSX ticker symbol

EMSX_AMOUNT

Data Types: struct

Order strategies, specified as a structure that contains the fields: EMSX_STRATEGY_NAME, EMSX_STRATEGY_FIELD_INDICATORS, and EMSX_STRATEGY_FIELDS. The structure field values must align with the strategy fields specified by EMSX_STRATEGY_NAME. For details about strategy fields and ordering, see getBrokerInfo.

Convert EMSX_STRATEGY_FIELD_INDICATORS to a 32-bit signed integer using int32. Set EMSX_STRATEGY_FIELD_INDICATORS equal to 0 for each field to use the field data setting in EMSX_FIELD_DATA. Or, set EMSX_STRATEGY_FIELD_INDICATORS equal to 1 to ignore the data in EMSX_FIELD_DATA.

Example: strat.EMSX_STRATEGY_NAME = 'SSP';
strat.EMSX_STRATEGY_FIELD_INDICATORS = int32([0 0 0]);
strat.EMSX_STRATEGY_FIELDS = {'09:30:00','14:30:00',50};

Data Types: struct

Timeout value, specified as a nonnegative integer. This integer denotes the time, in milliseconds, that the event handler listens to the event queue for each iteration of the code. The event handler can be a default or custom event handler.

Data Types: double

Options for a custom event handler or timeout value, specified as a structure. To reuse the settings for specifying a custom event handler or timeout value for the event handler, use the options structure.

For example, specify using a custom event handler and a timeout value of 200 milliseconds.

options.useDefaultEventHandler = false;
options.timeOut = 200;

Data Types: struct

Output Arguments
