AROON Indicator is great for reading trends, watch
as the "Up Line" (Default color:Yellow) reaches 100 means a strong up
trend, and watch for the "Down Line" (Default color:Dodger Blue)
reaches 100 means a strong down trend. AROON Indicator watchs also as
they crosses each other. It's great for signaling.
interval: more than 30 minutes;
period : 20.
Please give it a comment and don't
hesitate..please let me know if i could help you with some other
indicator that you wish to know.
