What is a forex swap?
Swap, also called rollover, is the interest cost or credit for holding a position overnight. It comes from the gap between the two currencies' interest rates, plus the broker's markup.
Most of the time swap is a cost. For long holds it can matter as much as the spread.
The formula in plain words
- Swap is usually quoted in points. One point is one tenth of a pip.
- Per night = swap points times lots times the pip value of one lot, divided by 10.
- Total = per night times the number of nights.
Per night = (Swap points × Lots × Pip value per lot) ÷ 10
Worked example
A 1 lot buy with a long swap of minus 5.2 points, held 10 nights
- 1Per night: (minus 5.2 × 1 × $10) ÷ 10 = minus $5.20.
- 2For 10 nights: minus $5.20 × 10 = minus $52.
Holding this trade 10 nights costs about $52 in swap, on top of the spread.
Common mistakes
- Forgetting the triple swap day. Many brokers charge three nights on one weekday to cover the weekend. Check your broker's day.
- Using last month's swap rates. Brokers change them when interest rates move.
- Assuming a positive swap will stay positive. It can flip.
