Sensex Today | Stock Market LIVE Updates: Oil prices are down this morning, which is a positive, while the Dow futures have also surged on media reports of the US sending Iran a plan to end the war. The Nifty did cross 23,000 on Tuesday but could not sustain above it, closing off the highs. That remains the key level to watch as a sustained move above 23,000 could trigger a further short squeeze.
