Examples
Retrieve Money.Net Real-Time Data for One Symbol
Create Money.Net web socket interface connection c
using a user name
and password.
username = "user@company.com"; pwd = "999999"; c = moneynetws(username,pwd);
Retrieve Money.Net real-time data updates for the IBM® symbol.
symbol = "IBM";
realtime(c,symbol)
The default event handler mnWSRealTimeEventHandler
processes all real-time data updates. To access the code for the default
event handler, enter edit
mnWSRealTimeEventHandler.m
.
mnWSRealTimeEventHandler
creates the workspace variable
IBMRealTime
. The
mnWSRealTimeEventHandler
function populates the table
IBMRealTime
with real-time data updates. To see the
real-time data, open IBMRealTime
in the Variables
editor.
Stop the symbol subscription.
stop(c)
mnWSRealTimeEventHandler
stops processing all real-time
data updates. The last real-time data update remains in
IBMRealTime
.
Close the Money.Net web socket interface connection.
close(c)
Retrieve Money.Net Real-Time Data for Multiple Symbols
Create Money.Net web socket interface connection c
using a user name
and password.
username = "user@company.com"; pwd = "999999"; c = moneynetws(username,pwd);
Retrieve Money.Net real-time data updates for the symbols IBM and Google®.
symbols = ["IBM" "GOOG"]; realtime(c,symbols)
The default event handler mnWSRealTimeEventHandler
processes all real-time data updates. To access the code for the default
event handler, enter edit
mnWSRealTimeEventHandler.m
.
The mnWSRealTimeEventHandler
function creates the
workspace variables IBMRealTime
and
GOOGRealTime
. The
mnWSRealTimeEventHandler
function populates the
tables IBMRealTime
and GOOGRealTime
with real-time data updates. To see the real-time data, open either variable
in the Variables editor.
Stop all symbol subscriptions.
stop(c)
mnWSRealTimeEventHandler
stops processing all real-time
data updates. The last real-time data update remains in each workspace
variable.
Close the Money.Net web socket interface connection.
close(c)
Retrieve Money.Net Real-Time Data Using Custom Event Handler
Create Money.Net web socket interface connection c
using a user name
and password.
username = "user@company.com"; pwd = "999999"; c = moneynetws(username,pwd);
Define a custom event handler function myfcn
. The
myfcn
function displays real-time Money.Net data to
the Command Window. You can write a custom function that processes real-time
data updates differently. For details, see Writing and Running Custom Event Handler Functions.
myfcn = @(x)disp(x);
Retrieve Money.Net real-time data updates for the IBM symbol using myfcn
.
symbol = "IBM";
realtime(c,symbol,myfcn)
myfcn
displays real-time data updates for IBM in the Command Window.
Stop the symbol subscription.
stop(c)
myfcn
stops displaying real-time data updates in the
Command Window.
Close the Money.Net web socket interface connection.
close(c)
Input Arguments
c
— Money.Net web socket interface connection
moneynetws
object
Money.Net web socket interface connection, specified as a moneynetws
object created using the moneynetws
function.
symbols
— Money.Net symbol list
character vector | cell array of character vectors | string scalar | string array
Money.Net symbol list, specified as a character vector, cell array of character vectors, string scalar, or a string array. To specify one symbol, use a character vector or string scalar. To specify multiple symbols, use a cell array of character vectors or a string array.
Example: "IBM"
Example: ["IBM" "GOOG"]
Data Types: char
| cell
| string
eventhandler
— Event handler
"mnWSRealTimeEventHandler"
(default) | character vector | string scalar | function handle
Event handler, specified as a character vector, string scalar, or a
function handle that specifies the name of the event handler function. Write
a custom event handler function to process any type of real-time Money.Net
events. This function must have at least one input argument that is a table.
The table format must be similar to the format of the output argument in
getdata
. The event handler
function returns all available fields when it executes for the first time.
The event handler function executes every time Money.Net provides a
real-time update. For details about custom event handler functions, see
Writing and Running Custom Event Handler Functions.
For example, to display real-time data updates in the Command Window, enter this code to define a custom event handler function:
symbol = "IBM";
myfcn = @(x)disp(x);
realtime(c,symbol,myfcn)
If you do not specify a custom event handler function, the default event
handler mnWSRealTimeEventHandler
runs. To access the
code for the default event handler, enter edit
mnWSRealTimeEventHandler.m
.
The mnWSRealTimeEventHandler
function creates a
workspace variable. The workspace variable name is a concatenation of the
symbol name and the word RealTime
. For example,
mnWSRealTimeEventHandler
populates real-time data
for the symbol IBM into IBMRealTime
. This workspace variable
is a table with variables for each field. The values in the table change
when Money.Net provides a real-time data update. Empty fields from Money.Net
populate as NaN
, NaT
, and so on,
depending on the data type.
First, mnWSRealTimeEventHandler
runs using a table of
current data. Then, mnWSRealTimeEventHandler
runs each
time an update occurs.
