Jim I disagree. A professional day trader needs an excellent fundamental knowledge of the economy, global affairs and what drives markets. That knowledge then reinforces their opinion on why a SP is behaving as exhibited through the charts.
I'm here because I have an interest in Slater & Gordon not SGH. I have no interest in trading the stock 'today'.
A good day trader is a very skilled operator not dissimilar to a long-term investor. Yes, I would agree traits are somewhat different but the level of skill required is on par.
Then again your description "
ramp this dog crap stock hunched over your computer clicking the buy and sell buttons"
suggests your definition is more aligned to dog track gambler. My interpretation of what a day trader is may well differ to yours.
