A potential chance to sell short will be when the re-bounce away from the 38. Since the price already break away from priceline, a new priceline and resistance might be created in the next few weeks (which means 38 will no longer be the resistance) and short sellers have to determine a new resistance for entry. From then on, price will decelerate at a rapid speed and a trailing stop-loss (around 10%) will be a good strategy to maximize profit target.
*Above mentioned is only my own opinion. Please bid at your own risk should you take in my idea. Thank you and have a nice week! =)
