With momentum indicators showing further improvement and the Nifty 50 holding firmly above its short-term moving averages, both of which are sloping upwards, the index could extend its gains for a third consecutive session and move above the immediate resistance zone of 23,150-23,200 (near October swing high of 23,175). A decisive move above this range could take the index towards 23,500, which is likely to act as a crucial hurdle.
