The hourly charts shows a support at 14.74 and this is what I would use as my first support. The support at 13.87 is much stronger but you have to weigh your own risk. I don't believe it will go down to that level so I think getting in sooner will be better than later.
The last 3 days the open has been near the lows. If you want to play it safe, buy right at open and put a stop at 2 or 3% below your buy. Worst case you lose 3% but you may enjoy the ride up.
I see that it has had bad press lately but I find there is more truth in the charts than the press.
