Mumbai: The BSE faced technical issues on Thursday, with some traders reporting problems in executing orders in certain futures and options (F&O) contracts. The disruption, which came on the day of the weekly Sensex expiry, prompted traders to take to social media to flag issues with order execution.

BSE said in a post on X that it experienced a brief outage from 9.42 am, affecting one of the partitions in the cash segment and the securities mapped to it, while all other partitions operated normally. "The issue was resolved, and normal operations resumed at 10.08 am," BSE said. Separately, several brokers reported disruptions on their platforms.
