GBPUSD Lot Size Calculator
GBP/USD, nicknamed "Cable," is known for its higher volatility compared to EUR/USD. This pair can move 100+ pips daily, especially during London session and UK economic releases. Accurate position sizing is crucial for managing the inherent volatility.
GBPUSD moves 1.5-2x more than EURUSD daily, yet both have identical pip values. This means the same lot size carries significantly more risk in Cable. UK political events, BOE decisions, and Brexit-related news can cause sudden 50-100 pip spikes. Traders who use EURUSD position sizes for GBPUSD often blow accounts during volatile news events.
