    // Manual calculation for comparative purpose:
    // 1. Buy price: 100.0 USD
    // 2. Markup: Amount 3500 IDR → converted to USD = 3500 / 16500 = ~0.21212121 USD
    // 3. Converted buy price: 100 + 0.21212121 = ~100.21212121 USD
    // 4. Exchange rate USD → IDR = 16500
    // 5. Final sell price: 100.21212121 * 16500 = 1_653_500.0 IDR
