Yeah, trading future contract, is highly risky especially if you are going on a high leverage, in which ways, you just need to stay close to your computer order wise, you may be faced with liquidation notifications everytime, informing you to add funds.
However, to trader future contract, you must be experienced with good knowledge of the market. I have tried future trading, it was difficult because I couldn't wait all day long to take profits, and i always closing my position without profits. I think future is not good for me, but i love margin options.
