Below is a chart of the set up I'm looking at:
I believe that we are in the last third of this up trend and in this part of up trends speculative stocks tend to be the biggest movers. Although I believe that this stock has the potential to explode. I think it is better to set a realistic target that offers good risk/reward and monitor price action around this level to either get out completely, take a piece and tighten a trailing stop or continue holding looking for more R's. The levels are marked on the chart.
Good luck and good trading!
