UVXY poorly timed!!

My timing was a fair way out on this baby, but seriously how is it possible that my upward estimate was an understatement??? Only wish I had the confidence to have held my position longer. I was buying heaps under $15 and got rid of them all by the time they hit $30 LOL!

Need to learn a little more about where to set a trailing stop I think.

Anybody got any tips?
