I use scottrade, because of the low trade cost, although it isn't the best one, I think that Etrade is.
If you haven't already I would HIGHLY, I MEAN HIGHLY suggest practicing in VSE (virtualstockexchange.com) - it gets you ready for what you really are going to do. Try and find a game that is realistic and start off using the same amount of money that you are going to invest in real life. Treat it like a real stock exchange, with YOUR MONEY.
my dad made me do this in the begging of my trading and it helped a lot.
And please don't try penny stocks, when I was doing VSE i had no idea on what they were, and when i started investing my real money, I was like "This stock just doubled in one day!!", so I found a high volume penny stock, and bought up shares, and guess what, the next week I was down over 2,000$ so i pulled out all of my shares and the next week the company left the exchange, went bankrupt a while ago.
I also suggest knowing the company, I mean everything about them, their past reports, news, if they have opened any new offices, how much it cost them to open those new offices, have they laid people of or are they hiring? What are there future plans are.
I'm sure you've heard this from nearly everybody and you will continue to hear it... but I have to say it.... Don't expect to make it big in a short time, investing takes time, and with that time usually comes rewards.
Also look up Regulation T, I'm serious I got hit hard by this, I was a repeated offender because I didn't understand it, and I wasn't allowed to trade for 90 days or something like that. -READ IT< KNOW IT
I wouldn't suggest buying in foreign markets yet, because that takes an entirely new spin on things,.
Obviously don't buy stocks that have gone a lot in a day, cause they will probably go down the next.
I think that that is it.. OHH yea NO COULDA, SHOULDA, WOULDA.. what i mean is.. oh man i had that stock, i shoulda kept it, or ohh man i woulda bought that stock if it was a dollar lower, and look at it now it's up x%. That will just get you even more depresed and in a bad mood, and it will make you double guess every trade that you make.
Play it safe. And good luck.
- - I guess if you can try and buy Apple before the WWDC starts, cause they introduce the 3G, i think when they first introduced the iPhone stocks went from 80ish to 100ish, and when people started getting their hands on them it went from 110ish to 130ish. And now with Apple with their iPhones all around the world, sales are only going to go up. --
^If any one feels like disagreeing with me go ahead, but right now a majority of my money is APPL
ONE LAST THING, and probably the most important,-- ***Keep Your Portfolio Diversified--** So have some in energy, but also some in blue chip, and have some in consumer goods..etc., because if one sector takes a big hit one day and all you had was that one sector, you are going to get hit BIG!
