Hi Rojac
Congratulations on break even. You are right about the charts. They are interesting, but in this kind of explosive growth situation, they break down. They are more useful once a stock reaches full maturity- and Wave won't be there for years.
You could do what others do and establish a core positon that you hold as a long position, and then establish a smaller trading position and trade in and out, either locking in profits, or trying to buy back on the pull backs to increase the number of shares you own.
It's a nice problem to have.
