| Currency Pair | Long Swap Rate | Short Swap Rate |
|---|---|---|
| EUR/USD | 0.15% | -0.50% |
Let’s say you’re long EUR/USD with a pip value of $10. The swap rate for long EUR/USD is 0.15%. To calculate the rollover interest, you would multiply the pip value by the swap rate and divide by 10:
Rollover Interest = ($10 x 0.15%) / 10 = $0.015
In this example, you would earn $0.015 in rollover interest for holding the long EUR/USD position overnight.
