QLD is long from an average price of $59. As of this writing it is trading at $104.03. This is a prime example of having patiently waited to buy at the right price and now selling it into strength at nice gains. The exit zone is $103.48 to $105.73.
If you want to keep it simple, you may consider exiting right here. On the other hand if you want to squeeze in potentially more juice, then scale out but put a stop right under the low band of the exit zone.
