In the realm of forex trading, a spread comprises two values: the bid price, representing the buying rate, and the ask price, indicating the selling rate.
The bid price is what a forex broker offers to pay for a currency, while the asking price is the rate at which the broker is willing to sell the same currency.
Simply put, the bid price allows you, as a forex trader, to sell the base currency, while the asking price facilitates your purchase of the base currency.
