Syntax

realtime(c,symbols)
realtime(c,symbols,eventhandler)

Description

realtime(c,symbols) subscribes to real-time data updates using the Money.Net web socket interface connection c for the specified symbols. The default event handler function mnWSRealTimeEventHandler processes and retrieves real-time data updates for each specified symbol.

example

realtime(c,symbols,eventhandler) processes real-time data updates using a custom event handler function eventhandler.

Examples

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)

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)

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

collapse all

Money.Net web socket interface connection, specified as a moneynetws object created using the moneynetws function.

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

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.
