Horizontal white line is previous R drawn from daily chart.
This is a 2 minute chart:
edit - I tranposed two numbers in the poll. The poll question should read $65.40, not $64.50. I tried to delete the thread but the forum software doesn't allow it.
I picked $65.40 because it was definitely above the line. I know sometimes price will go a little bit beyond a certain level before reversing, so I just wanted to leave a little extra room.
