What is a Swap Calculator?
A swap calculator helps traders estimate the overnight financing charges (or credits) when holding forex positions past the daily rollover time (typically 5 PM EST). These swap rates are based on interest rate differentials between currency pairs.
Understanding swap costs is crucial for swing traders and position traders who hold trades for days or weeks. Some traders even use swap-positive strategies (carry trades) to earn interest while trading.
