If the EUR/USD and GBP/USD currency pairs are positively correlated, this means that they tend to move in the same direction. For traders holding positions in both pairs, this correlation can significantly influence their trading strategy. When both pairs are positively correlated, a trader might consider increasing their exposure to the market by taking long positions in both pairs simultaneously. This strategy allows them to leverage potential profits, as gains in one pair are likely mirrored by gains in the other due to their similar movements. However, it also increases risk; if the market moves against them, losses could accumulate in both positions simultaneously.
