Session overlaps in Sri Lanka

London–New York, and the shorter Sydney–Tokyo and Tokyo–London overlaps, on SLST.

Forex session overlaps in SLST
Overlap	Mid-January	Mid-July
Sydney + Tokyo	05:30 – 10:30 (5 h)	05:30 – 11:30 (6 h)
Tokyo + London	13:30 – 14:30 (1 h)	12:30 – 14:30 (2 h)

Why London–New York, with the source

London and New York overlap when the two largest trading locations' business days coincide; the UK alone handled 38% of global FX turnover in April 2025 (BIS). That is a fact about volume by location, not a forecast for any pair or hour.

Broker hours, with a source

The week runs from Sunday 17:00 to Friday 17:00 New York time. Brokers differ by minutes: OANDA lists 17:05 to 16:59 with a daily 16:59–17:05 break (OANDA, checked 7 October 2026).

Does daylight saving change forex hours in Sri Lanka?

Sri Lanka stays on UTC+5:30 all year.

How the clock changes move the sessions

The session times on this clock still move by an hour, because New York, London and Sydney change their clocks, on different dates. The live clock above applies every change for today's date.

Method and privacy

Method: Times are computed from the Asia/Colombo time zone and each centre's own zone on two reference Wednesdays, 14 January and 15 July 2026; the rules repeat each year. Sessions are conventional local business hours, and the week is Sunday to Friday 17:00 New York time. Holidays, the daily 17:00 New York break and broker server time are not modelled.

Common questions

What time does the forex market open in Sri Lanka?

Monday at 02:30 SLST in mid-July and Monday at 03:30 SLST in mid-January: that is Sunday 17:00 New York time, the usual weekly open. Brokers can open a few minutes later; OANDA, for example, publishes 17:05 New York time.

What time does the London session open in Sri Lanka?

At 13:30 SLST in mid-January and 12:30 SLST in mid-July, for London's 08:00 to 17:00 business day. London is the largest FX trading location, with 38% of turnover in April 2025 according to the BIS.

What time does the New York session open in Sri Lanka?

At 18:30 SLST in mid-January and 17:30 SLST in mid-July, for New York's 08:00 to 17:00 business day. It closes at 03:30 (next day) and 02:30 (next day) respectively.

When do the London and New York sessions overlap in Sri Lanka?

18:30–22:30 SLST in mid-January and 17:30–21:30 SLST in mid-July: the 4 hours when both business days run at once. Whether that window suits a strategy depends on the pair, the costs and the news calendar.

Is the forex market open on weekends in Sri Lanka?

No. Spot forex closes at Friday 17:00 New York time (Saturday 02:30 SLST in mid-July and Saturday 03:30 SLST in mid-January) and reopens at Sunday 17:00 New York time (Monday 02:30 SLST in mid-July and Monday 03:30 SLST in mid-January). Some brokers quote other products at weekends; that is not the interbank forex week.

Limits and trading risk

These tools calculate from your inputs, supported historical records or explicitly labelled teaching examples. They do not verify a live account, predict future returns or confirm that a broker or prop-firm rule has been met. Missing costs, floating losses and changed market conditions can materially change outcomes. Trading can lose the capital committed to it; check the stated method and your account specifications.
