Eminis are definetelly great, but the downside is you have to be already a pro to trader them or have cash to burn. Not a good way to start trading. If you are a new trader, definetelly something to stay away from.
Strart with stocks, once you are good and consistent with them, than move on to eminis. Otherwise, you will most likely lose all or a lot of your capital. They are very volitile and require a lot of experience to trade them.
