When investors are about to make a purchase of a stock, they might notice a bid price and an ask price on their trading platform dashboard.

The bid-ask spread refers to the difference between the prices quoted for an immediate sale or purchase of a stock, currency pair, or commodity futures contract. Exchange rates can play an important role in the bid-ask spread, therefore, understanding how they are calculated can be a critical tool in realizing the impact of the bid-ask spread.

Key Takeaways

  • Ask price is what the forex market is willing to sell the currency.
  • Bid price is what the forex market is willing to buy the currency.
  • The spread is the gap between the ask price and bid price.
  • Exchange rates inform you how much your money is worth in another currency.
  • The spread can also confirm liquidity conditions in currency markets.



Understanding Exchange Rates in Forex Trading

For the most part, exchange rates are based on supply and demand in the global financial market. In other cases, exchange rates might be fixed or pegged to the value of another country's currency. They tell you how much your currency is worth in a separate currency. Forex traders might also monitor the spreads to determine broader liquidity conditions in currency markets.

At first, it might appear confusing, but once you regularly trade forex, it becomes second nature.

For example, if you are thinking about trading USD/CHF, this is the Swiss franc-to-dollar exchange rate. The currency on the left is the base currency, while the currency on the right is the quote currency. If the USD/CHF exchange rate is 1.5, this means one Swiss franc will purchase $1.50. Should the exchange rate climb, this signifies that the base currency has surged in value and vice versa.
