*new to elitetrader, but not a newbie to trading.
If you are not flexible, in my book, you won't succeed as an investor.
When I buy stock, and plan on a quick entry/exit, I set a goal of what price a want the stock to reach. Daytrading is a hard hobby/life-style... 80% of DTers fail.
This is why I consider myself to be more of a "day-to-two-or-three-or-w/e-ammount-of-days trader". Do not feel pressured to sell your stock immediately if you have a dollar increase. If you are dealing with three grand, its difficult to make noticeable money if you are constantly buying/selling and dealing with the fees that coem along with it.
If you buy you 20 dollar stock, just wait for a few days... most likely it will go down/up quite a bit, but sell it when you make a buck or two on each share... the market will run its course, and eventually you will meet that goal (trust me).
I hope I am not just rambling on, but i would find 2 solid stocks, stock A and stock B. As they both fluctuate, say A rises by one dollar, sell it. Research for a new buy, and by the time you are buying your new stock C(a day or two)... stock B will possibly have made you some money, and you can go on looking for stock D. etc, etc.
With three grand it is key that you focus n a few stocks, and wait patiently to make profit. If you rush into selling and buying, fees will eat you up and you will become frustrated and fail.
Chill-ax is the biggest piece of advise i can give you. The market is rough, and daytrading will be too.
