Traders tend to be more risk takers than traditional investors -- so we would like something that is both professional yet also a bit fun/edgy.
Keywords for the design are Wealth, Freedom, Rebel, Class, Fun, Excitement, Lifestyle, Success. Generally, the logo obviously doesn't need to convey all of that, but it needs to at least not conflict with any of those desired feelings/impressions.
In terms of possible imagery and look -- we want the words 'Trading Mavericks' spelled out with emphasis on the 'T' and the 'M'. We'd like to see the symbol based on those letters. NO cartoons please! We want to see glossy/3D effects, reflections, shadows, etc. for a nice web 2.0 feel.
In terms of color, we'd like to see versions in navy/royal blue or a deep green. Secondary colors are grey, silver, black, white.
Looking forward to your creative brilliance and good luck!
