If you’re looking to start your own forex brokerage, one technical term you can’t afford to ignore is Low Latency Trading. Latency is basically the time delay between when a trading signal is initiated and when it actually gets executed on an exchange. In fast-moving markets like forex, crypto, and equities, even a few milliseconds can determine whether a trade is profitable or not.
For brokerages that cater to high-frequency or institutional traders, this delay needs to be as close to zero as technologically possible.

So in this article, we’ll break down what low latency trading actually means, how it works under the hood, and what it looks like in real-world brokerage setups.
What Is Low Latency Trading?
Low latency trading refers to the practice of executing trades with minimal delay between the moment a signal is generated and when the order hits the market.
We’re talking microseconds, literally millionths of a second. In fast-moving markets like forex or crypto, that can make a measurable difference.
When you hear about latency in this context, it’s usually broken into three layers:
- Network latency – The time it takes for data to travel between systems (for example, your server and the exchange).
- Processing latency – The time your systems take to process incoming data and send an order.
- Execution latency – The time the exchange or liquidity provider takes to fill that order.
Low latency trading is all about optimizing each of those components. You might’ve seen high-frequency trading firms colocate servers right next to exchange data centers.
How Fast Is Low Latency Trading?
In the professional space, low latency is often measured in microseconds. Some hedge funds and prop firms operate with latency under 100 microseconds. That’s faster than the blink of an eye by several magnitudes.
Retail platforms and most brokerages don’t need to be that fast. If your execution times are under 50 milliseconds, you’re already doing better than many platforms out there.
Anything above 200ms starts to feel sluggish, especially for traders using scalping or arbitrage strategies.
For your brokerage, hitting sub-100ms execution will be considered decent. But it depends on your clients. If you’re targeting professional traders or automation-focused clients, latency becomes more than just a number, it turns into a marketing point.
Speed benchmarks vary, but here’s a rough idea:
- Retail broker latency: 100 to 300 milliseconds
- Professional trading platforms: 5 to 50 milliseconds
- Ultra-low latency systems (co-located or optimized FIX API): less than 1 millisecond
When clients ask, How fast is your execution?, what they really want to know is your average round-trip time. That includes the time it takes to send the order, have it executed, and receive confirmation.
The latency stack you can actually control
Latency comes from multiple layers. Each layer can be measured and reduced.
1) Market data ingestion
Direct feeds matter. Equity venues broadcast UDP multicast feeds like ITCH. Futures venues deliver low latency multicast feeds such as MDP 3.0.
If you must use consolidated feeds or vendor APIs, measure the added delay and jitter, then decide if the convenience is worth it.
2) Strategy and risk checks
Your signal code and risk checks belong close to the feed handler and order sender. Hot code paths should be branch-light and cache-friendly.
Precompute anything you can. Keep objects flat and fixed-size. Garbage collection pauses and unpredictable memory allocation are latency traps.
3) Order entry
You’ll serialize orders to the venue protocol, send them over low hop count links, and confirm with acknowledgements.
Co-location or proximity hosting cuts distance. Cross connects minimize third party hops. On the software side, a lean, single-responsibility order sender often beats a monolith.
4) Time synchronization and observability
If your clocks drift, you can’t trust your measurements. Precision Time Protocol (PTP) with hardware timestamping is the baseline in modern venues.
Many regulators expect tight synchronization to UTC. Even when you operate outside those rules, accurate time makes your post-trade analysis honest.
Why It Matters for Your Brokerage
You probably don’t need to compete with Jump Trading or Citadel. But offering fast execution can make a real difference to client experience and retention.
Traders don’t like slippage. They hate rejected orders. And nothing drives someone to switch platforms faster than getting filled 5 pips away from their expected price.
Here’s how low latency can benefit your brokerage:
- Better fill quality – You improve the odds of executing at the intended price.
- Happier algo traders – Bots are highly sensitive to delay. Low latency means fewer rejected orders.
- Marketing leverage – You can use execution speed as part of your brokerage’s value proposition.
Of course, you also need to make sure you’re not just “fast” but also stable. There’s no point offering 10ms execution if your servers crash during high volume.
Examples in Equities, Futures, and FX
Low latency trading strategies are commonly deployed across asset classes, each with its own infrastructure and timing sensitivities.
In equities, firms like Jane Street or Two Sigma often engage in low latency trading by reacting to market-making opportunities on exchanges like NASDAQ or NYSE.
Here, latency isn’t just about speed, it’s about queue priority. If your order reaches the book a few microseconds ahead, you get the better queue position.
In futures, the CME Group is a major hub for low latency action. Many prop trading firms colocate their servers at Aurora, Illinois, where the CME’s data center is located.
These traders execute strategies like spread arbitrage or statistical arbitrage that require execution within 10-50 microseconds to be effective.
In foreign exchange (FX), latency becomes even more interesting because there’s no centralized exchange. Traders need direct connectivity to multiple liquidity providers. A delay of even 20ms can cause you to miss a quote or get filled at a worse price.
This is where smart order routing and aggregated liquidity feeds become extremely useful for FX brokers targeting speed-conscious traders.
