ARNA has been a great trading stock over the last year.  my last few posted trades were made in another blog before i started this site but you can see how well this stock trades between these resistance levels by viewing those past charts (2nd and 3rd charts below).  the first chart below is today’s chart showing how ARNA has pullback back to the top of a support zone (former resistance/trigger area for the last long-side trade).  keep in mind this is a very volatile stock so adjust your position size accordingly if you take it.  most objective entry would be on another pull-back to that support zone with stops not too far below the bottom of the zone.
