"You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

Every day I grab a copy of the additions to the symbol guide from
http://iqfeed.net/symbolguide/display.cfm?eight=08011D32.cfm&six=0600036C&title=DTN%20-%20U.S.%20STOCKS%20-%20ADDITIONS

In today's file, I see a number of symbols that were retired after acquisitions. For example: AFFX, BDBD, CTCT, CYBX, DMND, DYAX (and there are quite a few more).

Assuming these companies haven't all been spun out again, it looks like there's a bug in the code that generates the symbol list.

These symbols were added automatically with NASDAQ update the night of 5/4.
With the exception of LMKRP, none have updated. At first glance seem to have been sent in error.
All invalid symbols will be removed.
