1.0 Depends if you use Fundamental Analysis or not

. Short-term trading, not so important. You can see trends happening regardless on your 5-minute chart. As you trade longer terms, news, interest rates etc. become more important to determine bull or bear pressure. But forex is very efficient, the big boys adjust their positions very quickly, which means the markets react to news quickly. Use every trick you can to stay alive. My favorite trick is paying attention.
2.0 I know lots of guys who have no problem trading short term using only technical analysis. One word of warning: don't trust these markets. They're sneaky.

They don't reverse when you want them to reverse. They can just keep on going against you forever, or until you're wiped out, at which point they of course validate your original position. BUY STRENGTH, SELL WEAKNESS. These aren't dot-coms. They're currencies of massive countries. They're strong or weak for a reason. And you won't catch many tops and bottoms so just give up and relearn how to lay back and follow the trend.
3.0 If you're good, you can easily make more money on forex than the stock markets, because of long, sustained, beeee - yoootiful trends and insane leverage (which is deadly but fun). Unless you're on the other side of the trend, in which case you're worm food, of course.
It's not uncommon for someone with $100k to make $2-3k daytrading with half-decent money management (ie suicidal). Shoot for half that and you'll live longer.
Of course, I also have a friend who was trading for a government agency (this is a VERY VERY TRUE STORY) and she lost just under ***$1 Billion Dollars*** of taxpayer money on one highly-leveraged Yen trade a few years back (like 10 years). And they didn't even fire her. They didn't seem to care. It's not their money. It was the first story she told me when we met. What an icebreaker. Don't let it happen to you.
Trade the mornings. Get up early if you don't want to miss out on the best "action". And remember, tight stops, me boy, tight stops. Because once you start trading forex, you'll realize that you don't know anything at all about trading, and neither do I. Only the market knows what's going on. So listen close.
Oh yes, my usual offer applies: if you have a Silver Bullet that makes you a Billionaire, feel free to PM it to me. I will discretely put it to good use, I promise.
