groupRouteOrder
Syntax
Description
groupRouteOrder(___,'useDefaultEventHandler',false)
routes a group of Bloomberg EMSX orders using any of the previous input argument combinations and a custom
event handler function. Write a custom event handler to process the events associated with
routing a group of orders. This syntax does not have an output argument because the custom
event handler processes the contents of the event queue.
___ = groupRouteOrder(
uses the c
,order
,options
)options
structure to customize the output, which is useful for
configuring and saving your options for repeated use. The available
options
structure fields are timeOut
and
useDefaultEventHandler
. Use the events
output
argument when the useDefaultEventHandler
field is set to
true
, and omit this output argument when the
useDefaultEventHandler
field is set to false
.
Examples
Route Group of Bloomberg EMSX Orders Using Default Event Handler
Using a Bloomberg EMSX connection, route a group of Bloomberg EMSX orders.
To create a Bloomberg EMSX order, create the connection c
using
emsx
and set up the order subscription using
orders
. For an example showing these activities, see Create and Manage Bloomberg EMSX Order.
Create the order request structure order1
to define the order
parameters. In this case, the code creates a buy market order for 100 shares of
IBM®. The 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
.
order1.EMSX_TICKER = 'IBM'; order1.EMSX_AMOUNT = int32(100); order1.EMSX_ORDER_TYPE = 'MKT'; order1.EMSX_BROKER = 'BB'; order1.EMSX_TIF = 'DAY'; order1.EMSX_HAND_INSTRUCTION = 'ANY'; order1.EMSX_SIDE = 'BUY';
Create the order using the Bloomberg EMSX connection c
and order1
.
events = createOrder(c,order1)
events = struct with fields: EMSX_SEQUENCE: 354646 MESSAGE: 'Order created'
The default event handler processes the events associated with creating the order.
createOrder
returns events
as a structure that
contains these fields:
EMSX_SEQUENCE
— Bloomberg EMSX order numberMESSAGE
— Bloomberg EMSX message
Create another order request structure order2
to define the order
parameters. In this case, the code creates a buy market order for 200 shares of
IBM. The 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
.
order2.EMSX_TICKER = 'IBM'; order2.EMSX_AMOUNT = int32(200); order2.EMSX_ORDER_TYPE = 'MKT'; order2.EMSX_BROKER = 'BB'; order2.EMSX_TIF = 'DAY'; order2.EMSX_HAND_INSTRUCTION = 'ANY'; order2.EMSX_SIDE = 'BUY';
Create the second order using the Bloomberg EMSX connection c
and order2
.
events = createOrder(c,order2)
events = struct with fields: EMSX_SEQUENCE: 354777 MESSAGE: 'Order created'
Route the two existing orders. Specify the order numbers, broker, and hand
instruction in the order
structure.

orders. events

— Bloomberg EMSX route identifierMESSAGE
— Bloomberg EMSX message
Close the Bloomberg EMSX connection.

— Options for custom event handler or timeout value
structure
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.

Data Types: struct
Output Arguments
events
— Event queue contents
double | structure
