If you're looking to download a mobile trading software, you can go to your brokerage's official website to download it.

However, if you're just looking for market information, you can give Guosen Securities' Gold Sun mobile trading software a try. It has more robust features than Big Wisdom and Tonghuashun, and is relatively easy to use. The software has all the necessary trading functions, and its user-friendly interface makes it easy to view graphics and charts. Gold Sun supports various mobile phone platforms, including Nokia, Dopod, Samsung, Motorola, Sony Ericsson, Sharp, Coolpad, Blackberry, and Apple. The app's trading speed is also quite fast, and it provides you with powerful information services from the Guosen Research Institute while displaying market trends, giving you the latest market views and operational strategies.

One of the best things about Gold Sun is that it's free to use, and only generates data traffic. Additionally, it has a special version designed specifically for Tianyu mobile phones. Gold Sun is a platform developed by Guosen Securities themselves, so you can rest assured that your personal information is safe and secure. It's also the only domestic mobile trading app that supports viewing of global index market information.
