World record? Not quite. Let's see full details on the numbers. NASDAQ publishes their latency numbers weekly, including average, 99th percentile, and 99.9th percentile: http://www.nasdaqtrader.com/trader.aspx?id=inet http://www.nasdaqtrader.com/trader.aspx?id=inet. Their average latency on order entry is 98 microseconds and their average latency on market data is 92 microseconds. Perhaps by "world record" they mean "european record".
- danielnicollet 16y agoTrue but this is like the "World Series" for stock trading latency. Who really plays baseball other than the US and small group of other countries like Cuba ;-)

- lrm242 16y agoGo read the website I linked to. NASDAQ publishes their methodology. I'll quote it for you here: OUCH Measurements of Order Latency * The time it takes to accept, process, and acknowledge or fill an order. * Measured as the complete round trip for an order or cancel transaction leaving a customer network port, through the co-lo network and application firewalls to the matching engine and back. * Measured in the production environment during a full trading day including opening and close. As you can see, they are including the time it takes to acknowledge and fill the order. It is the complete round trip time, and does include transit latency through the co-located network (which I thought was excluded).

- Rimpinths 16y agoThey are clustered together because it takes roughly the same amount of time to determine that an order can be matched (filled) or that it can't be matched (acknowledged, on the book.) Either way, it has to be processed by the matching engine.
