Market Wizards by Jack D. Schwager (pg. 183)

In trading, you can define three categories of players: the trade, the floor, and the speculator. The trade has the best product knowledge and the best ways of getting out of positions. For example, if they are caught in a bad position in the futures markets, they can offset their risk in the cash market. The floor has the advantage of speed. You can never be faster than the floor. While the speculator doesn’t have the product knowledge of the speed, he does have the advantage of not having to play. The speculator can choose to only bet when the odds are in his favor. That is an important positional advantage.
