Market hours guides

Short, hand-written explainers for the questions that come up most about trading hours, daylight saving, and sessions. Reference only, never advice.

• US market hours for IST tradersWhat time do the NYSE and Nasdaq open and close in Indian Standard Time? Regular, pre-market, and after-hours timings, and why they shift by an hour twice a year.
• The DST clock gapThe US and Europe change their clocks on different weekends, so the London-New York overlap moves for a few weeks each spring and autumn. Exact dates for this year and next.
• Pre-market vs regular hoursHow pre-market and after-hours sessions differ from regular trading hours on US exchanges: when they run, why liquidity is thinner, and why access depends on your broker.
• Crypto is 24/7, volume follows sessionsSpot crypto has no opening bell or closing bell, yet volume tends to cluster when European and US business hours overlap. How both facts fit together.
• The Sunday forex openThe forex week starts on Sunday evening in New York, when Monday morning arrives in Sydney. What time that is in UTC and IST, and why the exact minute depends on your broker.
• Forex session names explainedWhat the Sydney, Tokyo, London, and New York forex sessions are, how they hand over to each other, and where the overlaps fall. Session names are conventions, not exchange bells.
