The break is over 48. Could wait until 50.25 if you are worried we are a little deep into the apex. I noted the rising support line as a place to put your stops, but a couple % under the 50D SMA is a little bit closer and likely just as effective.
This stalled and stalled under the breakout level (which is a huge bearish hint). Now a false break out this week. We are getting very deep into the apex, and this might be a failed pattern if it doesn't reverse above 49 soon.
