"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
"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Data appears missing for symbols that have periods in the name. I've tried RDS.A, RDS.B, BRK.A, BRK.B.

Symbol is recognized and historical data and company name populates, but "Last" and "Close" and maybe some other fields do not populate.

Hello,

I do see this same thing here. I am not sure if it was intended as part of a reset for the next day's trading or if it was related to some weekend maintenance. I will look into that. I have no doubt this will all correct on the first trade of the morning tomorrow though, but we'll watch for that as well.

Tim
