There are a few longer than that, but 5 seconds is pretty much the standard we use. THANKS Stan S What we do today, determines how people remember us forever. Be the positive force in someone life.

Market Breadth indicators such as tick, trin, advancers, decliners, etc update every 5 seconds. "Premiums" such as the S&P Premium, etc all update tick by tick when the future or index updates. For the breadth indicators, we are working on increasing the update frequency (faster than every 5 seconds) as well... more to come on this soon. Jay Froscheiser DTN - Trading Markets
