RUSS just had a 700% climb and blow off top. Amazing stuff. I haven't played it nearly as well as I wanted but I didn't loose money and it is not over yet. But at the top a had still managed to blow a third of my account only to gain most of it back.
The lessons are two:
1. At extreme tops it's better to go long the long ETF. (Which I did)
2. Do not short inverse ETFs if there is not a clear peak pattern. (Which I didn't)
