Hi,
Yeah for options in particular I've never actually seen IB release any 'close' price. But I would double check that you're comparing the same tick type in TWS to that being returned through the API - they should definitely match. I'm not sure what is meant by 1.07 'or' 1.11 is expected. If necessary you can post the 'detailed' TWS log snippet; it will show the data being returned.?
By the way the code shows the tickerId being set as NextOrderId - please note these are different fields.
