Danodog, As a new trader.....
Please be VERY careful in your trading, particularly with a relatively small, though I'm sure hard-earned, nestegg of $4200! As others have advised, read, learn, and papertrade for as long as it takes. Then, when you are ready to trade, you need to not only pick and execute good trades, but also have money management strategies or rules to guide you.
For example, I NEVER put more than 10% (and usually no more than 5%) of my trading account into any one stock. I have in the past not followed that strategy and been badly burned on what appeared to be "can't miss" or "sure thing" trades. Just trust me on this, there are NO SUCH TRADES! I am sure you will come across some of these trades and be tempted, but set your limits and STICK to them! Preserve your capital, stay in the game, and find another trade tomorrow! If you lose your capital, you are out! Don't put yourseldf in the position where a small number of bad trades can devastate your account. Also, once you have started trading and have a few wins, do not let it go to your head and continue to use sound money management principles.
Best wishes to you in your trading!
Off my soapbox for now,
TC
