can you apply a profitable forex strategy to currency futures?

6E isn't one of the choices on the Open E Cry futures trading demo. Am I doing something wrong?

There's something else called EUR/USD, but it doesn't match the EUR/USD in forex.

 

E7

 

I have something called E7M8 in my Open E Cry demo. Is that the same thing? It's similar to what Oanda is displaying on the EUR/USD but not exact.
