These periods can lead to unpredictable price swings, increased spreads, and reduced liquidity, posing significant risks. Traders must exercise caution, implement robust risk management strategies, and consider reducing exposure during these turbulent times to safeguard their capital and avoid potential pitfalls in the forex trading industry.
