With bulls regaining control and the Nifty 50 trading decisively above its short- and medium-term moving averages, supported by strengthening bullish momentum and easing crude oil prices, the market is expected to maintain its upward bias. The Nifty 50 is likely to overcome the immediate hurdle at 23,500 and could attempt to fill the bearish gap formed on September 9 by moving decisively above 23,600.
