"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

I try to get Option chains for weekly options on ES. (Symbol is @EW) According to the API docu I do that with the following request (c#): "CFO,@EW,pc,FGHJKMNQUVXZ,123457,,\r\n" In my understanding this should return all Option chains from 2011-2015. Trying the same vor 2016-2017 give me the Option chains starting with @EWX16 to @EWJ17 (all are in the future from today) By probing some single strikes I was able to download historical data so I know the data exists. Does somebody have an idea what I'm doing wrong? Many thanks Erich

Currently, all you can do is the same kind of probing that you have already started using I am sorry to say. Tim
