Once stocks falls in hands of trader. it needs lot of push to break the pattern. Ujaas is such example. People/traders used to buy at around 43 and sell at around 49. As many people started doing it. It formed another resistance at around 46. So some who got it at 50 (e.g. Myself) would avoided it if looked the chart to enter either around 43 or best if it breaks 52.
