Not quite, far better than that. 12.2% for a four month hold to be more accurate. Nov buy - Feb close, Feb sell - Feb close. Selling a hold is no different to shorting. They are both shorting in effect.
I and I suspect many others are interested in trading gold, it is the only way to make a buck out of holding it. While timing is impossible it is fairly predictable to trade within a range.
You don't own the forum (I presume!) and therefore others are free to talk about trades and overall opinion of gold as an investment.
