to pay attention to details. Please don't take it wrong way, you can be a much better trader. Your words:
"UYG 不懂它是怎么操作的,本来是想靠它来赌 financial sector上扬的,谁知道financial sector 跌它也涨(同学们查查)".
Where did you find "financial sector 跌"? XLF? AH means nothing. So far, it is just a section rotation and it is still a bear rally. Just my 2 cents.
