Please go back and check and you'll se the data is missing for the symbols stated above, and I am sur for many more based on my limited test... everyone can see I am right by trying to request the data, nothing false about that...
Oh, they can? Well that's funny, because I just went onto Quantopian and checked for myself.
Gee, would you look at that...they are there.
This took me all of five minutes. Do you have anything else I can easily disprove while I'm at it?
I'm not searching for a needle in a haystack for you. Make a falsifiable claim, and make the entire claim, with the specific dates you're talking about, or stop this astroturfing against Quantopian and QuantConnect that you're doing.
