For day traders the most active hours are between opening the London markets and closing the US markets. The peak trading time is when the US and London markets converge. Usually, these hours are when the largest amount of trades occur and are considered the most desirable in terms of trading opportunities.   The key sessions for traders are the markets in London, the US, and Asia. Between summer and winter months, market opening and closing times change, as many countries transition to/from daylight savings time (DST). Above in table is an overview of the trading sessions that will help you make the most of the market.
