I like the idea in #1. I would prefer to see the scorpion wrapped around the "wording" trader versus as part of the "T" In #2, I don't care for the $ sign for the "S" in scorpion.
For your first entry, Could you try putting the scorpion to the left instead of as the "T" and could you also try doing it in between scorpion and trader. Could we also see what it would look like above the scorpion trader words and then making the slogan larger.
