The local benchmark -- Nifty -- ended the session on flat note on Monday. Market made positive start, as Central Board of Direct Taxes (CBDT) said the net personal income and corporate taxes collection grew 74 per cent to Rs 5.70 lakh crore so far this fiscal, driven mainly by advance tax and TDS payments. Further, market turned volatile, as RBI data showed the country's foreign exchange reserves declined by $1.47 billion to $639.642 billion in the week ended September 17.
