Definition

The difference between the quoted buying and selling prices at the same time.

What you need to know

In OANDA US’s spread-based forex pricing, commission is included in the spread, and in the IG International CFD example, the spread may vary with liquidity. Even without a separate commission, the spread may be part of the transaction cost. A published minimum spread is not a guaranteed execution price; in the US stock market too, the quoted price may differ from the execution price.
