Using a WDS connection, subscribe to two securities and process real-time
events by using an event handler function. Then cancel the subscription.
Create a WDS connection.
c = wind;
Format output data for currency.
format bank
Using the 0002.HK and 0003.HK securities and the
WDS connection, retrieve real-time data for the last price, volume, and last volume fields.
Process real-time data events using the sample event handler function
windEventHandler. You can use the sample event handler function or
create a custom event handler function to process events.
s = {'0002.HK','0003.HK'};
f = {'rt_last','rt_vol','rt_last_vol'}};
requestid = realtime(c,s,f,@(varargin)windEventHandler(varargin))
requestid =
uint64
5
requestid is the request identifier associated with the subscription.
The event handler function windEventHandler creates a variable in the
MATLAB® workspace named winddata. This variable contains the
subscription data.
