Forex Brokers Evaluation: Execution Speed and Slippage

When you’re just starting out in Forex trading, there are many things to learn. One of the most important factors to consider is the execution speed and slippage.

But what do these terms mean? And why are they so important? In this blog article, we’ll break down these concepts in simple terms and show you how they can affect your trades.

Why Execution Speed Matters in Forex Trading

Execution speed is all about–how quickly your broker can complete your order after you place it. In the fast-paced world of Forex, milliseconds matter.


For example:


You decide to buy EUR/USD at a specific price,

Next, you want that order filled immediately at that price.

But, if there’s any delay, the price might change.

So, it affects the outcome of your trade.

A broker with fast execution speed ensures you get the price you intended. Slow execution, on the other hand, can lead to missed opportunities or worse, losses.

Therefore, choosing a broker with high execution speed can be crucial. It’s especially vital during high-volatility periods like economic news releases.

What’s Slippage in Forex Trading

Now, let’s talk about slippage. Slippage happens when there’s a difference between:

  • The price you expect and
  • The actual price your trade is executed at.

This can occur due to market volatility, slow internet connection, or, sometimes, broker delays.

Here’s an example:


You want to buy EUR/USD at 1.1000.

By the time your order is executed, the price moves to 1.1005.

This 5-pip difference is called slippage.

But, most traders are concerned about negative slippage. It’s where the price moves against their intended direction.

How Execution Speed and Slippage are Connected

Execution speed and slippage are closely connected. When a broker executes trades quickly, there’s less chance for the price to change. Hence, this reduces slippage.

However, even the fastest brokers cannot entirely eliminate slippage. Factors like market volatility and liquidity also play a role.

But, a broker with fast execution can significantly minimize slippage. Therefore, that’s why it’s vital to evaluate both these aspects when choosing a Forex broker.

Examples: Calculating Execution Speed and Slippage

Let’s break down how execution speed and slippage work with simple examples.

Execution Speed Example:


Trader A places a buy order for 1 lot of EUR/USD at 1.1000.
The broker executes this order in 100 milliseconds (ms).

Meanwhile, Trader B places a similar order, but their broker takes 500 ms to execute it.
In the time between 100 ms and 500 ms, the price has moved from 1.1000 to 1.1003.

Trader A’s order is filled at the desired price. Meanwhile, Trader B suffers a 3-pip difference.
This shows how crucial execution speed is.

Slippage Example:


Suppose you want to sell USD/JPY at 110.00.
Due to high market volatility, by the time your order is executed, the price has moved to 109.95.
So, you experience a negative slippage of 5 pips.

If you had placed a buy order instead and the price moved to 110.05, you would have experienced positive slippage of 5 pips.
While slippage is a part of trading, having a broker with fast execution can help minimize it.

How to Evaluate Forex Brokers Based on Execution Speed and Slippage

So, how can you evaluate brokers based on execution speed and slippage? Here are some practical steps:

  1. Check Execution Speed: Look for brokers clearly stating their average execution speed. Many brokers will list this on their website. A speed under 200 milliseconds is considered good.
  2. Read Reviews: Trader reviews can provide good insights. They include: how often a broker experiences slippage and their average execution speed.
  3. Use a Demo Account: Test the broker’s platform with a demo account. The aim is to see their execution speed in real-time market conditions.
  4. Inquire About Order Types: Some brokers offer “guaranteed stop-loss” orders. They can help limit slippage in volatile markets.

Tips for Beginners to Minimize Slippage

Minimizing slippage involves choosing the right broker. And using smart trading strategies. Here are a few tips:

  • Choose a Broker with Fast Execution Speed: A broker with a fast order execution system reduces the risk of slippage.
  • Trade During Low Volatility: Avoid trading during news releases or other high-volatility periods when slippage is more likely to occur.
  • Use Limit Orders: Limit orders only execute at the price you specify or better. They can protect you from negative slippage but might not always be filled.

Quick Recaps

Execution speed and slippage are crucial factors for every Forex trader, especially beginners.
Always remember that slippage is inevitable. However, a broker with fast execution speed can help you minimize it.

Happy trading!
