Yes. I'm trading the eMinis.
Bascially you have a Initial fee, and maintenance fee.
Initial fee, typically 2,000 u$s, per contract., maintenance fee 1,600 u$s per contract.
This means that theoretically you could start with a 2,000 u$s account and buy/sell a future emini contract.
The broker would keep your position upto 400 u$s against you, then I believe you get a margin call.
Now if you wish to trade with no leverage at all, you would have aprox, 66,000 u$s, and buy 1 contract. Every point of the of the eMini es EG, YM 5u$s, NQ $20, ES $50, ER u$s100.
YM has no decimal places, so every tick is 5u$, NQ, goes in halfs, Every Tick is 10u$s, ES in 1/4 every tick 12.5u$s ER 1/10 every tick 10u$s.
Basically the predictor predicts the index, but as Futures, are correlate, I trade the Future. Some users I beelive trade the SPY, or DIA
Attached the trades for the day.
Take care.
