The market staged a healthy performance for the fourth straight session following a gap-up opening, with bulls celebrating Diwali—the festival of lights—and driving the Nifty 50 above the 25,800 zone with half a percent gains on October 20, a day ahead of the Muhurat trading session scheduled for the afternoon of October 21. The index has rallied more than 1,300 points so far this month. Despite pressure at higher levels, the higher high–higher low structure remains intact.

The Nifty Put-Call ratio (PCR), which indicates the mood of the market, fell to 1.15 on October 20, compared to 1.21 in the previous session.
