What is Latency and Why Does it Matter?

what does latency mean

Simply put, latency is any sort of delay or lapse of time between a request and its response. When it comes to trading, latency directly affects the amount of time it takes a trader to communicate with the market. Latency problems also adversely affect the prompt reception of relevant market information and the ability to act upon its receipt.

The key to long-term profitability is the speed at which traders access information and evaluate the market, then communicate the order to the broker that executes it at the desired price. To ensure that the time taken to complete the entire process is kept to a minimum, low latency connectivity is critical.

The likelihood of a trader gaining a competitive advantage or disadvantage because of latency’s impact on Forex trading has increased as technology-based trading has evolved. As far as the active trader is involved, to optimize the chances of success, latency needs to be evaluated and controlled.

One of the common issues when it comes to latency while using market data is known as “data lag“. Data lag is when there are data stream issues or inefficiencies. Many of these issues are totally out of your control as a trader, such as exchange platforms hardware issues and bottlenecks with internet connections.

They can happen without any warning, and they will not be noticed by the trader or anyone controlling the services. When it comes to ordering routing and execution, there can also be several challenges. These are also the situations where latency can have the most significant impact and can be the difference between a successful trade and a bad trade.

What is Slippage?


Slippage is a type of latency that defines the price difference between the expected execution of the trade and the price at which the trade is done. Slippage may affect the participants of the retail market. For example, due to the price difference between the time the order was submitted and the time it was performed on the server, market orders (an execution order type designed to fill in at the next available price level) can be executed at prices beyond what the trader expected.

The trading hierarchy and order

A successful trading experience depends on reliable order filing, and low slippage on these order fills. All this depends on the data on the market being delivered ahead of the competition.

The general sequence of order and execution goes along the lines of the order is entered remotely on an online trading website by a trader. Then the order is received and relayed by the broker to an exchange or market. The order is then placed in a queue at the exchange or market.

So, this usually’s how it goes:

  1. A trader enters an order on a trading platform,
  2. The broker receives an order,
  3. The broker relays the order to a market,
  4. The order is placed in a queue.

But there is a chance that latency may trigger some problems in the process during each stage listed above. In this case, the problem with latency is that some form of delay can mean that the order will be filled, but it will be filled at a price other than what it was executed at, so it will give you a much lower opening price than initially planned.

One of how high-frequency traders benefit to the detriment of slower trading investors is a trading practice known as latency arbitrage. Latency arbitrage is software that provides us with an almost guarantee of efficient trading by catching the imperfections of the slow broker, based on the quotes of the fast broker. It includes arbitration of prices obtained from individual exchanges with low latency in fractions of a second.

Latency Arbitration or Delay Arbitration is focused on the use of imperfections by brokers whose quotations are not in line with the market and visible to other brokers. These occurrences are very unusual and are typically caused by technological variables such as server load, delay in data transfer from the quotation provider, etc.

Of course, it is possible only with the assistance of a machine that compares such dependencies in real-time; here milliseconds are vital. It is possible, however, and there is a chance to raise the advantage on the trader’s side.

2. Using Workstations Designed for Trading

Upgrading the devices used in trading is one way of reducing latency in trading. It may be fashionable to use smartphones and tablets, but the fact is that they are not made for this. Their capabilities for data transmission are not designed to help fast-paced trading. Consumer-grade connectivity adds to latency as well; in some instances, up to one second.

One way to reduce the impact of latency on your trading without getting a Forex VPS is to change the assets you trade in. Gold is a “safe haven” asset that rarely falls in value and is rather stable.

The distance between the trader and the broker can influence the efficiency of the trading mechanism. Here is where a VPS (private virtual server) can help a lot. Hypervisor technology allows a server to be divided into several smaller VPS services. This server can host several virtual machines or VPS without performance issues. When you use a VPS for trading, it is usually called a Forex VPS.

Forex VPS is a remote device on which it is possible to host an expert advisor. The aim is to bring your trade robot as close as possible to the servers of the broker, which minimizes data lag.
