是不是今天又是买点  
I missed DGAZ after sold UGAZ, yesterday premarket DGAZ saw 14.46 my order 14.5 didn't even get it don't know why 
 
UGAZ you can start to buy 1/3 position if you really want, downside room limited, 20 around 
 
I sometimes use this strategy. 1/3 (in case miss an opportunity)  then when see the real hit, load what you plan to load 
 
 
recently UGAZ/DGAZ is not single side trend, so both of them easily got shrink b/c time decay, be aware of this
