"Bang for buck" can you think of a better alternative?
yes, CFD's. You can trade the futures contracts but are not limited to the contract sizes so you can position size for your stops much better, but the spread does make them a touch more expensive.
No matter what type of derivative you trade, opions, futures, warrants, cfd's, it still comes down to the combination of risk v's reward and win loss ratio.
Can you make $50k pa from a $7500 account, I wont say impossible because Larry Williams turned $10k into $1m and his daugher turned $10k into $100K at age 16. So I would say very difficult to make that sort of return, but it has been done.
