"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

Which one is the correct symbol to use for NYSE NET TICK? Thanks,

There may be a setting in your NeoTicker that is limiting the amount of historical data. Please contact us directly and we can take a closer look at your IQ Feed to confirm all is running properly. You can call us toll free in the US at 800-397-7000 or you use the live chat available from our web site www.IQFeed.net Stan S What we do today, determines how people remember us forever.

Stan S -DTN Guru- Posts: 256 Joined: Apr 13, 2006	Posted: Mar 30, 2011 09:12 AM Msg. 5 of 5 The TICK.Z & JTNT.Z are the same thing. The difference between venders data is due to these being vender calculated indexes. Each data vender figures the quotes themselves. The numbers will almost never match from 1 vender to the other, due to differences in how the data if calculated. All the indexes we calculate are on a 1 second refresh, if the other providers are using different time spans to calculate the index then the numbers will be different. Our Market Integrity dept and QuoteDev did extensive testing and research (March 2010) to try and determine why our TICK stat was a bit different from other vendors. We couldn’t nail it down because we are not certain how other vendors are calculating their stat. We are at a point where we would need somebody to get the exact details regarding how these other vendors are calculating their TICK. Obtaining this type of competitor information is highly unlikely. I hope this helps. Stan S What we do today, determines how people remember us forever. Be the positive force in someone life.
