Do I need a bank certificate to travel to HK?

Hi I'm from India and I'm planning on a 10 day visit to Hong Kong in February. I read some posts about having a minimum bank balance and everything so I just wanted to make sure what that's all about.

I can afford the tickets and stuff, and I'm planning to get the visa on arrival or apply for it online. This is my first time traveling to a foreign country; I do have my passport.

Am I missing anything? What more I need to do or have?
Thank you very much
