In South Africa, the forex markets open on Sunday at 10:00 pm local time. If daylight savings time (DST) is in effect in other countries or regions (South Africa does not observe DST) the forex markets will open at 11:00 PM local time. That said, it is always important to check with your broker to verify what opening hours it observes, and whether weekend trading is available. Globally, forex markets are generally open from 9:00 PM Coordinated Universal Time (UTC) on Sunday until 9:00 PM UTC on Friday, each week. South Africa, however, runs on South Africa Standard Time (SAST) which runs two full hours ahead of UTC.
