For those speculating in the market, what trading platform or tools are you actually using?

Goxtool (linux)
Sierra Chart (trading not yet released)
Exchange website (Mt. Gox, BTC-E, etc.)
Other software (?)

I'm new to trading bitcoin but have some experience with stocks and forex, and at first glance the Mt. Gox and BTC-E's platforms appear very primitive to what you would get on even basic services like E-Trade or Oanda. Wondering what people are actually using to execute their trades?

Thanks,
