I am new to QC and really impressed with the platform so far. I am particularly interested in options about which I have many questions.

To start, I am just wondering if we are missing a lot of option data this year, such as January 16, 22, 24, and everyday since February. The following script shows how many SPY contracts can be retrieved each day in the first quarter of 2018. The result shows essentially no data since Feb 1. Is this a known issue? Thanks.
