and look for the trading guides sections on both sites. Though I can't promise you that articles listed on both these sites would make you a "professional trader", it would probably be enough information to keep you busy for a while.
And don't forget the "10,000 hour rule". You need good practice, for at least 10,000 hours in order to become an expert or professional. So just because you read a bunch of stuff about technical analysis doesn't make you fully prepared. It does make you more aware of market dynamics, which is very important.
The best thing to keep in mind while trading is how much risk you can handle. Don't over expose yourself to any position. If you start feeling nervous and keep checking the price every 15 minutes, your position is too big. Close half of it and chill out.
