Trading a pullback in XNCR

So this has been rangebound for a long time, before gaining some good upside momentum in februry. It's been consolidating since then, until now. A breakout from DT line provides an entry for the next upswing, which I expect should be something similar to the first one.

Entry: now, or on further upside momentum
Trailing stop-loss 3 ATR from entry
1x target at previous pivot high, 2x target at 39
