I took a profit $EXPE at 9%.

I possessed $EXPE, but I think it would be decline, so I prepared for selling.
I would take a profit when price reach the 10%, but around 9.9%, NASDAQ has started decline. Affected by NASDAQ, $EXPE was also decline. so I took a profits about 9%.
It was good point, because after taking profit, price is go down.
next, I purchase $EXAS half position. It seems like price is walking on the band.
I will be more position when price go ride on the bollinger band.

I think aiming the riding bollinger band is good method. It will get a large profit when it success.
