Personally wouldn't. When trading gaps, one should wait for a positive reversal and with only $2 to $2.40, any positive reversal could eat up much of that 20% wanted.
Remember trade stocks with a chart pattern (Gap is OK,) but you want positive TA signals and increasing volumes to enter. Don't see all 3 in the chart. http://schrts.co/nMCcdIZi
Play what you want, not what's in front of you. Keep an eye on RAVE for a second of normally three; flag trades soon. http://schrts.co/tjEJIQcz
Consider averaging down the original hold, once a come back happens. This would be a modified get even plan I've posted about in the past.
Can't give link as I no longer have search, subscription has lapsed. So search 2018, 17 for "get even"
While I'm here, would like to comment about trading gaps again.
I mentioned it's OK to trade them, but often while waiting for a positive move entry, much of the gain expected is lost in that entry move. Making the play a waste of time.
Watching for single gaps are more of a support signal for me. To trade gaps alone one should want several to be pulling price up.
