Types of players in the Market

There are intra-day, short-term, mid-term and long-term traders in the Market. The intra-day traders can be called scalpers. The short-term ones are also known as swingers. The mid-term traders can be called position traders. The long-term ones are also known as investors.

I believe these 4 types of players contribute to the 3 types of price movement trends depicted in Dow theory, with scalpers and swingers contributing to 1 type of price movement.
