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

Overnight financing charges—often called swap or rollover fees—directly reduce your net profit or increase your losses when positions remain open past the daily rollover time. For forex and CFD traders, holding positions across multiple days means paying or earning the interest rate differential between the two currencies. While positive swaps can give a small boost, negative financing fees accumulate quickly and chip away at your floating equity.

In prop firm trading, these hidden costs matter immensely. Because accounts enforce strict daily loss limits and maximum drawdown rules, unmanaged swap fees can unexpectedly push your account closer to a breach threshold. Always check your broker's specifications before leaving swing trades open.
