How Good Is Your Broker’s Order Execution?
Order execution refers to the process of carrying out the buy or sell orders you place with your broker.
In a previous lesson, we looked at whether the prices shown on a broker’s platform are fair and accurate. But fair pricing doesn’t matter much if your trades don’t get filled at those prices.
It’s like ordering a delicious-looking cake from a bakery’s display photo—only to receive something completely different. That’s poor execution.
When it comes to trading, poor order execution can cost you money. That’s why it’s important to work with a broker who values quality execution and is transparent about how they handle your trades.
Understanding Order Execution: A Fun Analogy
Let’s revisit our fictional tale of Batman and Spider-Man for a moment:
Batman sees GBP/USD trading at 1.4100 and wants to go long. He places his $20 on the table. But Spider-Man delays—he "doesn’t hear" him. When Batman insists, Spider-Man says the price has moved to 1.4150. That’s a 50-pip difference. Batman just got “slipped.”
This is a classic case of slippage, where the price you get is worse than the one you saw. It’s something traders should be aware of when choosing a broker.
What Is an Order Execution Policy?
Reputable brokers should provide a document—usually called the Order Execution Policy—that explains how they process customer trades and aim to get the best possible result.
When reviewing this document, look for details about:
-
How they choose price feeds and sources.
-
How they select and monitor liquidity providers (LPs).
-
How they assess the performance and reliability of their trading technology.
-
How they manage conflicts of interest in order execution.
This document helps you understand how your trades will be handled and whether you can trust the broker to act in your best interest.
Key Questions to Ask About Execution Quality
To truly evaluate a broker, don’t just rely on what they advertise. Ask these important questions:
1. How committed are they to transparent execution?
Good brokers publish detailed execution statistics, including:
-
Average execution speed
-
Average spreads per currency pair
-
Slippage rates (both positive and negative)
-
Percentage of trades executed at requested prices
If this data isn’t available on their website, contact the broker and ask for it.
2. Who are their liquidity providers?
Find out if the broker:
-
Discloses its LPs
-
Reveals what percentage of trading volume each LP handles
-
Discloses any financial relationships or conflicts of interest with those LPs
This shows how independent and unbiased their pricing and execution may be.
3. Is execution fully automated?
Ask if trades are executed automatically, or if manual intervention ever occurs—and when. A fully automated process reduces the chances of manipulation.
4. What are their average spreads?
Ask for average spread data by currency pair. Ideally, you should also see spreads broken down by time of day (e.g., peak vs. non-peak hours).
5. What’s their execution speed?
Execution speed is how long it takes for your order to be filled. Fast execution (ideally under 0.1 second) gives you a better chance of getting the price you clicked.
Also ask:
-
What percentage of trades are executed in less than one second?
-
If trades often take longer, expect more slippage.
Let’s Talk About Slippage
Slippage happens when your trade is filled at a price different from what you requested. This can be:
-
Positive slippage (you get a better price)
-
Negative slippage (you get a worse price)
Ask your broker:
-
What percentage of orders receive positive slippage?
-
What is the average positive price improvement (in pips)?
-
What percentage receive negative slippage?
-
What is the average negative slippage?
These stats can be further broken down by order type (market, limit, stop). The more positive slippage—and the less negative—the better.
Can You Request Post-Trade Reports?
If you’re ever unsure why your order wasn’t filled at the expected price, ask your broker for a post-trade execution report. This should show whether your trade was handled according to their execution policy.
In the U.S., brokers are even required to provide data about the 15 trades that occurred before and after your trade in the same currency pair. This helps confirm if you were treated fairly.
Bottom Line: What Really Matters
Execution methods (like A-Book, B-Book, or STP) don’t automatically make a broker trustworthy. What matters most is how the broker runs its business.
Here’s what to look for:
✅ Transparent and fair pricing
✅ Honest and timely execution of orders
✅ Proper risk management and capitalization
✅ Fast and reliable withdrawal processing
✅ Licensed and regulated in credible jurisdictions
✅ Clear complaint handling procedures
If a broker isn’t upfront about these things—or refuses to answer questions—consider it a red flag.
The best brokers are open, honest, and committed to treating their customers fairly. Trust should be earned through transparency, not vague marketing.
