The naming of a company is usually done with business goals in mind*. If the whole idea of your LLC is just for your trading, and will ever be so, then the name doesn't matter.
*By "business goals in mind", I mean this:
say you intend to market your trading corp one day to accredited investors out there. You may want to name your corp. according to what you intend for it to do, such as "Boomer Financial Management, LLC" or "Asset Growth Strategy, LLC". That's because those keywords will denote your message to your intended clients. The name of your company won't throw them off**. But if it's just for you for now, and you're not sure what the future may hold for it, then keep it generic, because then it can be anything later on. And of course, for a small fee, you can always change the name (but then you have to redo banking accounts, etc).
**That reminds me of an advertising piece I got a couple of weeks ago. There was a picture of a house on one side, the text on the other had a headline that said something like, "Capperetta & Sons". That's all, just the name of the company. The body text went on to read, "You've worked a long hard day and now you're on your way home. You're thinking about your wife and children and their comfort that you work so hard for. Relax with the security that comes from knowing that we're here. With Capperetta & Sons you never have to worry. Call us today for an appointment..."
You know, they never said what their company was about and I'm thinking that they're either oil heat, alarm systems, insurance or the cosa nostra. The point I'm making is that their company name did not tell me anything about their business.
