The 20 days Simple moving average (20 days SMA) and 50 days Simple moving average (50 days SMA) for Nifty stand at 4977 and 4997 respectively. The 50 days SMA is above the 50 days SMA and the 100 days SMA which is at 5253.

Nifty is most likely to maintain above 20 days SMA for a minimum 7-8 days while breaking past 100 days SMA  i.e above 5250 also seems impossible. Not the right time to buy Nifty options, its better to let the market hit 5200 first.
