The derivatives benchmark GIFT Nifty is signalling a gap-up start for Indian markets on October 23, with futures trading around 26,280 (approx +1.56%) ahead of open. The momentum follows positive cues including renewed foreign inflows and hopes of a favourable US-India trade deal that could reduce Indian export tariffs to 15-16%. Analysts see a strong probability of the Nifty 50 breaching the previous all-time high near 26,277, with support placed around 25,700.
