Even though QuantConnect has reported the original issue I raised on this as fixed there are still missing files so I'm
not happy this was reported as fixed.

Checking from 1st April to current there are missing files for

On 2019-04-17 no options chain for ?QQQ On 2019-06-21 no options chain for ?QQQ

It's impossible to create reliable backtests with missing data.

May I ask how the original issue I reported was "fixed".
Was it a patch or was there some processing bug that was fixed?
Or is there some fundamental problem with the data source or processing that will result in missing files?
Does QC do any data verification for the back test data sources?

Thanks.
