Bank nifty after a sharp fall from today the market looks like its trying to go with negative side for few days as a small pull back .... Look for level 47650 to test and show the weakness .. and then can trade for a low with small target .... can expect a market fall about 900 points ... mostly trade is for Expiry day movement .... be carefull of the level 47000 and if market stucks there set as marginal profit zone ...
