This is really unbelievable.
The quality of this API is really low, which is especially evident in this problem.
I have now implemented something with Yahoo finance, which gives me the valid option chains.
Then I create all needed contracts and serialize them to a file(because it takes an enormous amount of time to get them).
That way, the cached contracts can be reloaded and only new expiration chains well need to be added.
But still, why do we need to do this?
We deserve better from IB, since all this data is available in the option trader window.
I now struggle in reveiving the greeks for the options. Are they even there when markets are closed?
