Understanding Interactive Brokers Forex Spreads: A Beginner’s Guide

When it comes to forex trading, one of the most important factors to consider is the spread. The spread refers to the difference between the bid and ask prices of a currency pair. It represents the cost of trading and can have a significant impact on your profitability. In this beginner’s guide, we will explore the concept of forex spreads and how they work on the Interactive Brokers platform.

Interactive Brokers is one of the leading online brokers in the forex market, known for its low-cost trading and vast range of financial instruments. They offer competitive spreads on a wide range of currency pairs, making it an attractive option for forex traders of all levels.


To understand forex spreads, let’s first define the bid and ask prices. The bid price is the highest price that a buyer is willing to pay for a currency pair, while the ask price is the lowest price that a seller is willing to accept. The difference between these two prices is the spread.

For example, let’s say the bid price for the EUR/USD currency pair is 1.2000, and the ask price is 1.2005. In this case, the spread would be 0.0005 or 5 pips. A pip is the smallest unit of measurement in forex trading and represents a one-digit movement in the fourth decimal place of a currency pair.

Interactive Brokers provides forex spreads in a fractional pip pricing format, which allows for greater precision in pricing. This means that spreads can be as low as 0.2 pips, providing traders with tighter bid/ask spreads and potentially lower trading costs.

It’s important to note that spreads can vary depending on market conditions, such as volatility and liquidity. During times of high volatility, spreads tend to widen as market participants demand higher compensation for taking on additional risk. On the other hand, during periods of low volatility, spreads may tighten as market conditions become calmer.

Interactive Brokers offers different types of forex spreads, including fixed spreads and tiered spreads. Fixed spreads remain constant regardless of market conditions, providing traders with more predictability in their trading costs. On the other hand, tiered spreads are variable and depend on the size of the trade and the trading volume. Traders with larger volumes can benefit from lower spreads, while smaller traders may face slightly wider spreads.

To access real-time forex spreads on the Interactive Brokers platform, traders can use the Trader Workstation (TWS) or the WebTrader. The TWS is a powerful trading platform that offers advanced charting tools, order types, and market data. The WebTrader is a web-based platform that allows traders to access their accounts and trade from any device with an internet connection.

In addition to spreads, Interactive Brokers also charges a commission on forex trades. The commission is based on a percentage of the trade value and is added to the spread. This commission-based pricing model can be beneficial for high-volume traders who can take advantage of the low spreads offered by Interactive Brokers.

When trading forex with Interactive Brokers, it’s essential to consider the overall trading costs, including spreads, commissions, and any additional fees. By understanding the various components of trading costs, traders can make more informed decisions and optimize their strategies for profitability.

In conclusion, understanding forex spreads is crucial for successful trading. Interactive Brokers offers competitive spreads on a wide range of currency pairs, providing traders with the opportunity to minimize their trading costs. By using their advanced trading platforms and taking advantage of their fractional pip pricing format, traders can access tight bid/ask spreads and enhance their trading experience. However, it’s important to consider other factors such as commissions and fees to determine the overall cost of trading.
