NIFTY
closed at day's low today. This could lead to some more fall tomorrow. However, it could have been done in order to make it option seller's day. :) Expiry is supposed to happen around 15650-15700 since max pain is at 15700. I can see good put writing at 15600 but heavy at 15500. There are more contracts on call side though at 15800. So anyhow in this expiry it should not go above 15800. 15600 is a good support level though.
