Eddyjo - my honest opinion would be not to touch futures through an 'ordinary' broker. Yet. At $50 a point you will be hung, drawn and quartered by other traders before you know what's happened to you.
If you are new or new-ish to trading, I would seriously suggest that you open a spread betting account, perhaps Financial Spreads. I suggest Fins because you can trade 1p a point for the first eight weeks I believe, and after that it goes up to a minimum of 50p. I bet you think I'm mad suggesting you trade such a pittance - I'm not, I'm just saddened when I see and hear about people who think the market is just one big orchard with every tree dripping in money, and all you have to do is idle up to a tree and harvest as much as you can carry.
Even at 50p a point, I guarantee you will lose. So assume you will lose, and lose, and lose, and therefore make it as painless as it can be - bet small. Paper trading is OK, but when you have to physically press a button or two to enter a trade, fear and other emotions will get the better of you. But, if you persevere with whatever strategy you choose, and learn to recognise and conquer the fear you will exhibit, then you can go on to great things trading-wise.
So, bet small, and try out the system first. I don't know the Champion system, so therefore I cannot comment on it. All I do know is that whatever your system, you'll go on an emotional rollercoaster before you get the profits you dream of. This is a hard game, and you need to be able to come back to the market day after day, when each previous day you've been given a good hard slap by the market and had your ego torn to shreds.
No book, course, or bulletin board will prepare you for the emotional side of trading, so expect the best but be prepared for the worst.
If you use Fins or CMC (Deal4free) you have access to their intraday charts with realtime prices as part of the service. Once you can consistently make money (the emphasis is on the word consistently), then you may wish to consider using an 'ordinary' online brokerage. But I suggest that is at least a year down the road.
ES is the ticker code for the Emini S&P futures, incidentally.
And do let us all know how you get on!
