createBasket

Create basket of Bloomberg EMSX orders

Since R2021a

Syntax

events = createBasket(c,basket,order)

events = createBasket(c,basket,'timeOut',timeout)

createBasket(___,'useDefaultEventHandler',false)

___ = createBasket(c,basket,options)

Description

events = createBasket(c,basket,order) creates a basket of Bloomberg^® EMSX orders using the Bloomberg EMSX connection with the Bloomberg EMSX C++ interface, basket name, and order request. createBasket returns the order sequence numbers and status message using the default event handler.

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

createBasket(___,'useDefaultEventHandler',false) creates a basket 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 creating a basket of orders. This syntax does not have an output argument because the custom event handler processes the contents of the event queue.

___ = createBasket(c,basket,options) uses the 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

Create Basket of Bloomberg EMSX Orders Using Default Event Handler

Using a Bloomberg EMSX connection, create a basket 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 Using Bloomberg EMSX C++ Interface.

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 number

• MESSAGE — 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'

Create a basket of the two existing orders. Specify the basket name. Then, specify the order numbers in the orders structure.

basket = 'OrderBasket';
orders.EMSX_SEQUENCE = [int32(354646);int32(354777)];
events = createBasket(c,basket,orders)

events =

  struct with fields:

    EMSX_SEQUENCE: [2×1 double]
    MESSAGE: 'Orders added to Basket'

• EMSX_SEQUENCE — Bloomberg EMSX order numbers

• MESSAGE — Bloomberg EMSX message

Close the Bloomberg EMSX connection.
