What is Forex Pip Conversion Mechanics?
Mathematical Foundation
Laws & Principles
- The Yen Exception: For all currency pairs containing the Japanese Yen (e.g., USD/JPY, EUR/JPY), exactly one pip is located at the second decimal place (0.01), unlike standard pairs where a pip is the fourth decimal place (0.0001).
- Static USD Quotes: If your account is denominated in USD, and you are trading a pair where USD is the quote (second) currency (e.g., EUR/USD, GBP/USD), a standard lot (100k) will always yield a perfectly static pip value of exactly $10.00.
- The Lot Sizing Law: Risk management requires dynamic lot sizing. Because a pip in EUR/GBP is worth significantly more in raw dollars than a pip in USD/JPY, trading '1 Standard Lot' uniformly across all pairs will result in wildly disproportionate monetary risk.
Step-by-Step Example Walkthrough
" You are trading a Standard Lot (100,000 units) of USD/CAD, and your broker account is denominated in US Dollars. The current USD/CAD exchange rate is 1.3500. "
- 1. Identify the Lot Size: 100,000 units.
- 2. Identify the Pip Value for CAD pairs: 0.0001.
- 3. Identify the Exchange Rate: 1.3500.
- 4. Calculate Raw Quote Value: (0.0001 / 1.3500) = 0.00007407 CAD.
- 5. Multiply by Lot Size: 0.00007407 * 100,000 = $7.407.
