When trading Forex, you might notice that your MetaTrader 4 or MetaTrader 5 chart displays only one price line by default. This line represents the Bid price. Understanding why MetaTrader charts typically show the Bid price and its implications is crucial for accurate trade execution and risk management.

Understanding Bid and Ask Prices

In the Forex market, every currency pair has two prices: the Bid price and the Ask price. The Bid price is the price at which you can sell the base currency, and it is also the price your broker is willing to buy it from you. Conversely, the Ask price (also known as the Offer price) is the price at which you can buy the base currency, or the price your broker is willing to sell it to you. The difference between the Ask and Bid price is the spread, which is a primary component of trading costs.

As stated in trading operations terms, buy orders are executed at the Ask price, while sale orders are executed at the Bid price.

Why MetaTrader Charts Show the Bid Price

The standard configuration across MetaTrader platforms is to display the Bid price line on the chart. This is a platform design choice that has become a widely accepted convention in the retail Forex trading industry. While the Ask price is always present and active in the market, it is not typically shown as a separate line on the default chart view.

For many traders, especially those primarily focused on selling or closing long positions, having the Bid price visible offers a direct reference point for their sell orders. However, it's important to remember that when you open a buy position, it will be executed at the (unseen) Ask price.

Practical Implications for Traders

Understanding Your Entry and Exit Points

  • Selling: If you are placing a sell order (e.g., Sell Market, Sell Limit, Sell Stop) or closing a buy position, the execution will occur at the Bid price shown on the chart.
  • Buying: If you are placing a buy order (e.g., Buy Market, Buy Limit, Buy Stop) or closing a sell position, the execution will occur at the Ask price. Since the Ask price is higher than the Bid price by the spread, your buy entry will always be slightly above the visible Bid line.

Impact on Stop Loss and Take Profit Levels

When setting Stop Loss or Take Profit levels, this bid-only display can lead to misunderstandings if not accounted for. For a buy position, your Stop Loss and Take Profit levels will be triggered by the Bid price, even though your entry was at the Ask price. For a sell position, these levels are triggered by the Ask price. Always factor in the spread when calculating these levels to ensure they are placed accurately relative to your intended entry or exit.

Many brokers, including RannForex, allow you to enable the Ask line on MetaTrader charts. This can be a valuable setting for traders who want to visualize both prices simultaneously, providing a clearer picture of the current spread and potential execution prices for both buy and sell orders. This feature helps in better assessing market conditions and managing trades effectively.

Avoiding Surprises

Being aware that MetaTrader charts default to the Bid price helps traders avoid surprises, particularly when dealing with tight spreads or volatile markets. It ensures that expectations for order execution, especially for buy orders where the Ask price is higher, are realistic.
