What is Order Execution Latency? Meaning, Example & Why It Matters
The time delay between placing an order and it being received, executed and confirmed by the exchange.
Order execution latency is how long it takes for your order to travel from your device or software, through your broker's systems, to the exchange and back with a confirmation. It is usually measured in milliseconds. Network quality, broker infrastructure, risk checks and exchange load all affect it.
Why Order Execution Latency matters to you
For long-term investors, a few hundred milliseconds rarely matters. For intraday traders, options scalpers and algo users, latency can affect the price you get, especially in fast markets. Higher latency increases the chance that the price moves before your order arrives, leading to slippage or missed fills.
Brokers rarely publish verified latency figures, and marketing claims can be hard to compare. Performance can also vary at peak times, such as market open, expiry days and major news events, when systems are under heavy load. Outages and app slowdowns at these moments are a real risk.
Practical tip: test your broker's platform during busy market periods before relying on it for time-sensitive trades. Have a backup plan, such as a second device or the broker's call-and-trade number, in case the app or internet connection fails.

Frequently asked questions
Does latency matter for long-term investing?
Usually very little. It matters more for active traders and automated strategies that depend on fast execution.
How can I reduce latency?
Use a stable, fast internet connection and a reliable device. Broker infrastructure also plays a big role, which you cannot control directly.
Do brokers publish their latency?
Some make claims, but independent, verified figures are rare. Testing during real market conditions is often the best guide.
