There is allot of info out there. You should have an education area with the brokerage that you are using. Or just google what you are looking for and it is all there. Lots of books also out there for you to learn with. Shorting a stock is just betting it will go down instead of going up. Do not believe most of the things you here on this board. Almost everyone has their own agenda and don't really give a damn about what you think or are doing. If you read something you think is a good deal just double check for yourself. Read everything you can or investing or trading can break you very fast. Never be afraid of taking a profit at any time, you will never go broke that way.
