On September 10, the BSE experienced a brief technical disruption that affected specific trading segments during the morning session. According to the BSE's official statement on X, the exchange experienced a brief outage from 9:42 am that affected one partition of the cash segment and the scrips mapped to it, while all other partitions continued to operate normally. The exchange confirmed that the issue was resolved and normal operations resumed at 10:08 am, with the entire outage lasting just 26 minutes. This brief outage coincided with the weekly F&O expiry day for the Sensex, making the timing particularly significant for traders engaged in futures and options trading. The disruption prompted traders to take to social media to flag issues with order execution, highlighting the impact on market participants during this critical trading period.
Traders raised significant concerns over glitches in the BSE order system on Thursday, with select Sensex option contracts reportedly frozen for trading during the expiry session. According to latest channel checks, some Sensex option contracts, particularly around the 75,000 strike price range, were impacted by the technical issues. However, not all futures and options contracts were affected, with trading continuing normally in some contracts. The frozen contracts created additional challenges for traders attempting to manage their positions during the critical expiry period, compounding the existing technical difficulties that began with the brief exchange outage. 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 across multiple platforms.
Despite the BSE's official resolution, several brokers reported disruptions on their trading platforms that were subsequently rectified. Zerodha confirmed the ongoing technical issues, stating on X at around 12:30 pm that there was an issue with price updates and order placement across brokers for F&O contracts on BSE. The brokerage informed customers that "We're in touch with the exchange to resolve this at the earliest," demonstrating the coordinated effort between exchanges and brokerages to address the technical difficulties. Zerodha later informed customers that the issue had been resolved, with the brokerage confirming the resolution through official channels. The platform disruptions extended beyond the exchange itself, affecting multiple brokerages and their trading interfaces for F&O contracts.
Despite the technical glitches affecting derivatives trading, Indian markets showed mixed performance during the session. According to The Economic Times, at around 1 PM, the Sensex was up about 60 points, or 0.09%, at 74,825, while the Nifty was higher by 14 points, or 0.06%, at 23,444.25. Market breadth remained mixed with about 1,867 shares advancing, 1,937 shares declining and 173 shares unchanged. The recovery from early losses was supported by broader market factors, including crude oil prices remaining above the $100-per-barrel mark amid geopolitical tensions and focus on upcoming US inflation data. The market's ability to trade despite ongoing technical issues highlights the underlying strength of current trading sentiment, with the disruptions primarily affecting derivatives trading rather than the broader market indices.
