The number I check before NSE opens, plus what the world did overnight. No ads, no noise.

Sessions: 6:30 AM - 3:40 PM and 4:35 PM - 2:45 AM IST, Monday to Friday. Placeholder price until the licensed feed lands.
The two I watch most are Seoul and Taipei: both are tech-heavy exporters, like Nifty IT, so a weak night there usually means a soft open here. All indices and their timings.
