Market Traders

Market traders are individuals or firms that buy and sell equities (stock traders) or currencies (Forex traders) or other financial assets.  In the United States, regulations require that all stock market transactions be timestamped to within seconds of UTC.  However, the trend over the past decade has been to obtain increasingly accurate timestamps.  First, using the Network Time Protocol (NTP) with a typical network client accuracy of 1/2 - 2 milliseconds, then progressing to the Precision Time Protocol (PTP/IEEE-1588) with a typical accuracy of within 100 nanoseconds (with hardware slaves).  Another method sometimes used by the trading community is IRIG-B.  This also yields a timing accuracy of 10 microseconds but is not very popular as it requires special cabling and computer cards.

High-Frequency Traders
One breed of market traders are High-Frequency Traders (HFT).  HFT is a term used for computer-algorithmic, high-volume, short-term trading.  The HFTs trade at the rate of more than 1000 per day, and they push the state-of-the-art in terms of network timing accuracy.  They co-locate their computer equipment only meters away from the market center computer equipment.  Doing this greatly reduces latency, giving these firms advance knowledge of market data just milliseconds before other market participants.  In these days of high-speed computers, a few milliseconds is a great advantage.

Using PTP/IEEE-1588
These co-located HFTs require very precise UTC time to track orders in the market by placing timestamps in their buy and sell messages.  Most HFTs have many computers running on a dedicated Local Area Network (LAN).  Typically, each LAN has a PTP Grandmaster Clock and each computer on the LAN is synchronized to the Grandmaster.  These parallel, high-speed computers must be accurately synchronized for the algorithms to process market data, and accurate timestamps are a crucial factor in the success of any HFT.
