I'll just hit the high points
Bid: That is the price the market maker is buying the stock from you at. Sometimes they will buy above this number.
Ask: That is the price the market maker is selling the stock to you. Sometimes they will sell it to you at less.
The numbers beside the bid and ask are those numbers.
A lot of diferent things cause the stock to move up or down. Generaly buying makes it go up, selling makes it go down.
If you see those numbers go up, the stock is going up. If you see those numbers go down, the stock is going down.
You can buy as many shares as you want at a certain price. You will not run them out of shares. But if you have a large buy in, the market maker will probably just sell you a portion of what you want, then bring the price up higher so he can sell you the rest at a higher price.
My advice to you: Play with pretend money before you put real money into stocks. Get a book or something and learn more about the market or you'll get butchered. Penny stocks are the most dangerous place in the market to be. If you don't know what you are doing, you are going to get hurt bad. And one last thing: Don`t trust anyone on these boards.
