Hi Sellnow
Depends what you have as the trading range and time scale.
I've got the trading range as support at 440 and resistance from an unconfirmed down trend at 580, and also the last major high. There is also shorter term support at 550.
The choice to short could be a strong one. I tend to look for a 3:1 win/loss ratio on TA, so at the moment Price = 554, Stop-loss=590 and a target = 440.
Loss=590-554 = 36
Win=554-440=114.
....so a short would be reasonable. All IMHO
