USDJPY Lot Size Calculator
USDJPY (Dollar Yen) is the second most traded currency pair globally. Its unique 2-decimal pip structure and sensitivity to Japanese central bank policy make it a favorite among forex traders. This calculator helps you size positions correctly for yen pairs.
Unlike EUR/USD which uses 4-decimal pip counting (0.0001), USDJPY uses 2-decimal pips (0.01). This means a move from 150.00 to 150.50 is 50 pips, not 5000 points. Additionally, the BOJ's intervention history means sudden 200-500 pip moves can occur without warning, requiring conservative position sizing.
