Mumbai, Oct. 27 -- The stock markets closed marginally lower on Tuesday amid continued pressure from elevated crude oil prices and caution ahead of the US Federal Reserve's policy decision.

The Nifty 50 index closed at 22,749.75, down 3.45 points or 0.02 per cent, while the BSE Sensex settled at 73,598.67, declining 8.08 points or 0.01 per cent.

Vinod Nair, Head of Research at Geojit Investments, said Indian equities ended flat after a volatile trading session, as high crude prices and caution ahead of the US Fed's policy decision overshadowed supportive global cues.
