Positions that remain open overnight are typically subject to a charge or credit known as swap, or overnight financing. This guide explains what swap is and why it's a relevant consideration for certain trading styles.
Understanding swap is particularly important for swing traders and position traders, who commonly hold positions across multiple days.
What Is Swap?
Swap (also called overnight financing) is a charge or credit applied when a position is held open past a specific daily cutoff time, often referred to as the session rollover. It generally reflects the interest rate differential between the two currencies in a forex pair, or financing costs relevant to other instrument types.
When Does Swap Apply?
Swap applies to positions held open past the rollover time, which typically occurs once per trading day (with some brokers applying a larger, multi-day charge over weekends to account for the days markets are closed). Positions that are opened and closed within the same day, before rollover, generally do not incur swap.
Why Swap Matters
Swap is an ongoing cost consideration for any trading style that involves holding positions overnight. Over time, and especially for positions held for extended periods (as in position trading), cumulative swap charges can become a meaningful factor in the overall cost of a trade.
🔖 Summary
Swap, or overnight financing, is a charge or credit applied to positions held open past the daily rollover time. It's an important cost consideration for swing and position traders, whose approaches commonly involve holding positions overnight.
Frequently Asked Questions
Does every overnight position get charged swap?
Swap generally applies to positions held past the rollover time, though specific terms and whether it's a charge or credit vary by instrument, direction and provider.
Can swap ever be a credit rather than a charge?
Yes, depending on the interest rate differential and position direction, swap can sometimes result in a credit rather than a charge.
Does day trading avoid swap entirely?
Yes, since day trading positions are closed within the same day before rollover, they typically avoid swap charges.
