Boing has been in an up trending channel and is currently sitting on the bottom of the channel and a support level. Looks like a great opportunity to catch the next move upward. Wait to confirm that the move is up and it doesn't break down out of the channel before entry.
I think your technical analysis is very good, but looks like now that it broke the channel (4/21), it may bounce a few times off 230, possibly 228.5 before heading up again. If we add in some basic fundamentals, IMO BA has a long slow road ahead to get investor confidence back. It's just barely a value stock anymore. Excellent chart. :)
