Calculator FAQ

Short answers about inputs, assumptions and limits.

What is a forex spread?

The spread is the difference between the buy and sell price of a currency pair. It is a built-in trading cost.

Swap fees are overnight financing charges or credits applied when a position is held past rollover. They vary by pair, direction and broker.

Why do spreads change during the day?
