#NIFTY50 mkt reaction on inflation is little big , by November end we might test the ATH of nifty , for this week expiry i expect nifty to be with in the range of 18500- 18150 levels , we might oscillate only with in these levels .. possible today mkt open at 18350 levels and then might not move up much and might see some profit booking and close around 18250 levels..
