1. MM's are market makers, and yes, that is level II they are referring to. I don't use Ihub's level II service, I use Etrade's. Every trader has their own preferences when it comes to what level II service they are using. VND? Maybe you mean VNDM (VANDHAM SECURITIES CORP. ,NEW YORK NY ,212-223-7510)- they are a MM.
2.Yes, short term traders trade often and take quick profits. They aren't in it for dividends or long term. Daytraders will trade one stock within a one day period. Swingtraders will sometimes hold for a period of days. Position traders will hold even longer waiting for a particular event. But they are all shorter term traders.
3. Yes long term is usually for 1+ years.
Oh and on the triple zero stocks...they are triple zero for a reason. Yes, it is possible to make money on a run but they are few and far between. It does happen, but don't be investing in a triple zero company. They are usually diluted pos's and eventually reverse split.
