However, there are times during the weekdays when the currency market is relatively calm and the trading volume is low.
It's typically best to avoid trading when only one trading session is available and instead wait for the trading periods to overlap. When two main financial centers are open, many more traders are willing to buy and sell a particular currency.

The most volume takes place during the London and New York trading sessions. More than half of all trading occurs during these sessions. The currency pair you choose to trade will determine an optimal moment for you to begin trading forex.
The majority of trading activity for a particular currency pair occurs when trading sessions for two currencies overlap.

For example, when both the Sydney and Tokyo trading sessions are open, AUD/JPY sees increased trading activity. EUR/USD will also experience more trading activity when the London and New York trading sessions are both open.

The ideal time to trade depends on the market and strategy. For forex traders, the overlap of major market sessions, such as the London-New York overlap (8:00 AM to 12:00 PM EST), is often ideal. This period sees heightened volatility and liquidity, offering more opportunities for price movement and tight spreads.

Stock traders typically focus on the first and last hours of the trading day. The opening hour often experiences high volatility as traders react to overnight news, while the last hour reflects end-of-day adjustments.

For commodities or indices, timing may depend on related market activity. Regardless, traders should align their trading with periods of higher activity and their strategy. Avoid trading during low-liquidity times, as spreads widen and execution may be less favourable.
