Hold a trade past the daily cut-off (about 5:00 pm New York) and your broker applies a swap: interest earned or paid on the position overnight.
Why it exists
Each currency has an interest rate. When you buy a pair, you effectively hold the base currency and borrow the quote. If the currency you hold pays more interest than the one you borrow, you may earn swap. If not, you pay.
You buy AUD/JPY when Australian rates are much higher than Japanese rates. Each night you may receive a small positive swap. Sell the same pair and you'd pay it.
Swing traders, check the swap before you hold for weeks. Scalpers, you can mostly ignore it. You're gone before the bell rings!
Find the swap rates in MT5: right-click the symbol → Specification. Brokers add a markup, so real swaps are smaller than the raw rate difference.
- Swap is overnight interest applied at rollover.
- It can be positive or negative depending on direction and rates.
- Wednesday usually charges three days to cover the weekend.
