It might be safer to wait till the reversal is confirmed. It's fighting the first level of resistance now. Then another around the 19.25 before it tackles that 19.75.
Looks to me that it could be a possible double bottom but needs to breakout before it can be confirmed, I think it needs more volume, it may fixing to put in a triple though because I don't see the volume one would expect as it gets close to breaking out. JMO
