Latency to popular brokers from our Trader's Desktop - a VPS for traders - Technical Support
Latency is the physical delay caused by the electrical signals passing through the various copper and fiber infrastructure that make up the core of communications networks. We measure it as the time it takes for a packet of information to reach your broker and come back. Ultra-low latency trading offers tremendous advantages for the trader because price quotes are received and orders entered before most other traders receive the same quote (usually several times over). This is most valuable during periods of volatile market activity when prices change quickly and latency may affect pricing. Low latency also offers the trader more reliable connectivity to the broker because there are fewer hops on the Internet for potential problems to impact the data transmission, requiring the data packet to be sent again at the expense of time. According to Wikipedia, A 1-millisecond advantage in trading applications can be worth $100 million a year.
