Robert: depending on the broker you trade they will ask you a "margin" per contract... (real front money in your acct), some brokers go from 500 to 2000 on eminis per contract... once you long/short a contract you have the minimum fluctuation "tick" that on the case of ym is $5 on er is $10 and lets say on ES its $12.5 so per example if you put a margin of 500 and you got a 7 tick move on you favor on er, you got 70 bucks minus comision (let say 3.5 round trip) 66.5 profit against 500 that is 13.3% profit... now that can happen oposite if you got stopped -7 ticks... on eminis you have "ranges"... er is the most volatile " high range" and es is the most "low range" emini... wich means : how much potential move you can expect on the future... this is a High risk, high potencial bussiness... you have to be very good at it or in a week go broke... cheers Walter.
