Based on HDFC Bank results on 21 st April if we analyze BN, HDFC Bank and All other BN index bank charts, every bank looks bearish to me !!!!!!! Based on 19th april closing data indicating complete bearishness only in all the banks chart. once the support area is broken we can see big fall in BN. on 22nd April if HDFC is bearish as per Q4 results then my prediction will work.
