Entry: Big morning spiker (+100%), no news, low float, first reversion was supported around 4.00. With no volume and testing the 3.9X was clear for me that the breakdown was quite profitable. As soon as I saw it break I managed to enter short in 3.75/share. Exit: following close, as soon as the short volume disappeared, I closed my trade in 3.17/share for an acceptable +.58/share (+15.50%). Lesson: I could have only closed half of the shares and continue the run for a bigger dip.
