Trends on SGX Nifty indicate a cautious opening for the index in India. Indian markets could open flat to mildly lower, in line with mildly negative Asian markets today and despite sharply negative US markets on Monday. "After Monday's sell-off of over 1 percent, the Nifty is expected to open flat to negative at 15730. Key levels to look out for Nifty is 15,600 as support and 15,860 as resistance. Traders are advised to book profit at every rise and exit all longs if 15,600 is broken. Fresh longs should be considered only if Nifty closes above 16000 levels," said Gaurav Udani, CEO & Founder, ThincRedBlu Securities.
