Hello newbie.
The forex market is open 24 hours, 6 days a week. However, during the crossover periods of major exchanges, the liquidity of the market increases. This liquidity, when paired with the volatility of the major pairs, becomes highly profitable. Hence, for a beginner, I will suggest that the best time to trade is in the crossover hours and the best pair is any of the major pairs.
