We can't tell you what to ask exactly, what we can advice is that you first take time time to read and observe the rules here and how things are done, then based on your interest, you will be able to fashion out some questions by yourself. I can see that "trading" is of interest to you, it will interest you to know that there is a board dedicated to trading and its discussions, certainly there will be things you can learn from there.

 Welcome and good luck on your time here.
