Not to be outdone, OCBC securities have an application for mobile trading as well.
Note: I am a current user of this application and while it is abit buggy initially I think I quite enjoy it.
The prices update are similar to that of the web portal one but being on a smartphone your screen will be switched off.
One thing that will make you feel bothered is that every time you launch the application, you have to enter your login credentials again.
Imagine I Just want to check the stock price of Yangzijiang I have to key in my userid and password.
The App is FREE. Download it from here
