Good news... the problem will be fixed on 7/18. We just need to include the
full expiration in the format of YYYYMMDD when invoking the reqContractDeta
ils( ) method.

just got an answer from IB API support.
1 minute issue should be solved in near future(when???)

Unfortunately IB imposes limitations on the amount of contracts
that can be returned when invoking the reqContractDetails( ) method.
In this particular case it would be best to include additional
contract parameters which will narrow your scope.
Example if you include m_expiration and m_right then you can
determine all the available strikes for that particular expiration.
Alternatively if you include m_strike and m_right you can determine
all the available expirations.
But please note there are currently an issue that development is
working on with respect to Option Contracts. It seems even though
you include the m_expiry there still is a 1 minute buffer for
additional requests. Once this has been resolved I will provide
you a follow-up comment on this ticket with additional details,

Hi, i experience same issues!
the first request answers quickly then a second after 1 minute
then nothing... :-(

I updated TWS and API to use latest stuff but even worse
with the <>clients.exe crash (previous API clients versions don't crash).

I'm going to log the issue to IB.

Yes, when i try to take the options chain every call to
reContractDetailsEx (with strike set to zero) lasts 1 minute instead the
normal 6 seconds. I also notice that the demo program of the API
(client3.exe) crash when you use "reqContractData". Can you try if you
have the same problem?

thanks

Is this still a problem? I just ran a program at 8:25 EST on 11 JUL, and
everything appears normal on Globex (E6).

hi everybody, i've a little program that that takes the chain of the
options using the method reqContractDetailsEx (ActiveX). It worked fine
till yesterday: every call to reqContractDetailsEx lasts 1 minute versus
the 6 seconds of before yesterday. In this way the program is
dramaticaly slow. Anyone experienced the same?
