A spread for a stock is the difference between the highest price that a buyer is willing to pay (the bid) and the lowest price that a seller is willing to accept (the ask). For example, the bid/ask rate for Tesla stock is $673,30/$673,58. You will buy the stock at the higher ask price of $673,58 and sell it at the lower bid price of $673,30. This represents a spread of 0,28 points. FBS provides competitive spreads on the stock market.
