How do overnight financing charges affect trades held for several days?

Overnight financing charges, often called swap fees, are interest payments applied to positions held open past the daily market close. If you are long on a currency pair or asset with a higher interest rate, you may earn interest, but if you hold the opposite, you pay a fee that accumulates daily. For swing traders, these charges directly impact your floating PnL and eat into your margins over several days. When trading with prop firms, managing these costs is critical because unexpected drawdowns from accumulated fees can unintentionally breach your daily loss limits or consistency rules. Always check your broker's swap rates before holding positions across multiple sessions. How do you factor swap fees into your swing trading strategy? Feel free to share your thoughts below!
