Expiry pressures out of the way, NIfty has hit the upper channel. If there is a gapup with breach of 17562, Nifty will look to break the downtrending channel. Likely scenario is 17375 getting breached. 17300 is a critical level and a gap to be filled, followed by a virgin cpr support below it. Strong selling could carry Nifty below 17246 to levels marked on the chart. Do you se the channel being respected tomorrow or broken?
