Quote from BCE:
Another thing in all this is to have a "feel" for and just familiarity with whatever it is you're trading in addition to a "feel" or knowledge of how the market reacts in different situations. This comes with experience. If you're trading the index futures against people that trade these everyday and have been for years, you'd better know what you're doing. They certainly do, at least the good traders. It really helps to track and observe whatever it is for a time. But it just depends what it is. I knew a guy that just traded 2 listed securities only, and mainly one, Citigroup, for over 10 years everyday and made 6 figures year in and year out just because he knew it so well.
Up or down that how simple it is. Agree!
