Spread

Ask

The ask is the price at which the market is offering to sell a currency pair to you.

The bid is the price at which the market is prepared to buy a currency pair from you.

Liquidity describes how readily transactions can occur without causing large price disruption.

The spread is the difference between the bid and ask prices.

Forex quotes have two prices: the bid and the ask. The gap between them is the spread, which is one of the costs of entering and exiting a trade.
