I'm not a fan of TWS API design at all (to say the least). But at this point it has so much history and dependencies that it is not feasible to improve it dramatically in an evolutionary manner. You probably know that being 30 years in software development. :)
On your topic... I think I just replied how I get the chains in another thread using?reqSecDefOptParams as Francois suggested.

Hi Francois,
thx for the links. All of this leaves me really speachless about the quality of the IB API. I am a professional software developer since >30years, but a function like reqSecDefOptParams?plays in the primary league of "worst design never". Not only does it return invalid data, but the concept inherently leads to massive server requests.
So sad, and since this topic is years old, IB obviously does not care. Do they even have a valid email adress to their developers?
