Deciding when to enter or exit a trade in the global indices market should be based on your advanced trading strategy.
When trading indices, you should closely monitor a range of fundamental factors, including economic news releases, geopolitical events and macroeconomic developments.
You can also make use of a variety of technical analysis tools to analyze index charts. This could be anything from detecting patterns on a candlestick chart to using Fibonacci retracement, or looking at moving averages and paying attention to the volatility index.
Once you have tested your trading strategy, you then need to check the opening and closing times of the markets you are trading.
You can see the full timetable in the Trading Hours section on this page.
