Be careful to those who reach you through private message here in bitcointalk.org, not all of them want to help you. We don't know if one of them or first on the list of them is want to take advantage on you, hope not. Thinking that is not too late. Better if you try to read all the instruction in bitfinex  official website on how to trade in different ways. Another option is to find some useful videos (recommended in youtube site ), videos that created to teach about how to make trade in bitfinex and other related things on that site. I recommend to teach/educate yourself too by joining some useful thread here in bitcointalk.org. It's okay if you are a noob or a beginner, we all start in that too and its a part of the process to be more successful someday! Good luck to your journey folks.
