"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

Or other variant

I select ( checklistbox ) in IQFeed Client properties, I want receive only tick's for history and realtime - from NYSE, NASDAQ, NASDAQ ECN, ( ARCA, BATS or other... ), and I have other data quality for stock, do not you think it's a simple solution?

IQFeed Client cuts all remaining ticks and have full compatibility with popular trading programs and nice datafeed for stock's !

Sorry English bad :)

Hello Jay

I understand, that can create program and filters through IQFeed API, but I not programmer, I use NinjaTrader and Multicharts, and this program not filter exchange tick's, and will not be filtered because it is not necessary developers.

Many popular trading platform not have filters, and this quality falls ( bad ) for IQFeed and use this datafeed for stock trading.

My simple sentence, filter ticks in IQFeed Client through Symbol-Suffix, this more faster and more promising for your company.

PS. Futures Exchange not have non liquid ECN

Debrief your partners ( developers ) who have a filter, and why they do not, exchange market data this not flash online games ?

Hello

InteractiveBrokers have clear exchange ticker, if select routing IBM|NYSE, MSFT|ISLAND, and send only exchange data, without other ECN.

ESignal have too, if select special suffix for example IBM=N, MSFT=Q.

IQFeed send Consolidated data Exchange + ECN, and this data poor with non liquid ECN.

Can You may create filters in your IQ Client ( datafeed ), and filter ticks through suffix, for example IBM-NYSE send only NYSE tick's, MSFT-NASD send only NASDAQ tick's ?

Programmers trading software ( Multicharts, Ninja, Sierra and other ) not trade on real money, and they not need filter's !

IQFeed can may change quality data for stock trader's, and it is not difficult for you.
