While the moving average convergence and divergence (MACD) indicator is experiencing an upward centerline crossover, the relative strength index (RSI), a momentum indicator, is positively poised. On the higher side, Rs. 850 is acting as an important psychological level; above this, we can expect a level of Rs. 900+ in the near-short term, while on the lower side, Rs. 770 will act as a major support during any correction.
