BN has broken open a strong s/r zone 41730-41650. it has also broken out of the short term trend line, which should act as support now. the OI data suggests that the expiry is likely to be in range of 41500-41800. due to expiry pressure we might not see much of upside movement. however in case of breakout above 41800 sustaining over 15 min candle, we could see a push towards 42000. for the intraday trade setup range could be 41650/41500 on downside and 41900/42000 on upside
