Nice trade on a recent IPO runner. Shorts get squeezed and the volatility offers opportunity. I got in with a wide $10 risk as this can gap a gift up gains very quickly. The 1st support level was @ 140 with 138 & 134 following "loosely" behind. I had a target of 172.95 and took half profits around 157.50 The resistance @ 170 was too great and volume too low so I sold as I was not planing to hold over the weekend.
