i am relatively new to futures, and have been reading and researching the es the past couple of weeks, here on et and through other sources. i was wondering what are some differences when deciding which to trade? i know the s&p is a much larger contract, but i dont know any specifics. a 1 point move in the es is +$50, what is a 1 point move in the s&p? what kinds of traders trade each? do they mirror each other, and if so, are the strategies applied to each reflective? basically, i just wanted some more info on the two, for any of yall out there who dont mind sharing this basic stuff. thanks.
