Indian benchmark indices remained volatile through the session on Wednesday but managed to close marginally higher. The markets will today react to the US Fed decision. Analysts say the ongoing consolidation for Nifty around the 61.8% retracement zone of the immediate swing (22,182–24,774) indicates a potential base formation at lower levels. Despite the recent stabilization, the index has not yet formed a Higher High–Higher Low structure, keeping the broader sentiment cautious.
