First of all, you're criticizing QuantConnect's data when you claim to get your data from ebay.

Second, yes you absolutely can verify QuantConnect's data. You can use it as much as you want within the context of their platform, you just can't download the data en masse from their platform and use it on your own. But if you have tick data (equities) or minute data (options) yourself, you can certainly verify it (which of course, you don't, because you think ebay is a good source for financial data).

I am going to continue griefing you in threads like this where you spread blatant misinformation, because at this point I'm convinced you have an ulterior motive or are in fact selling this data you keep talking about on ebay.

Unfortunately you cannot display QC tic data to be able to very it against you broker for example. As I said before if you have a good and cheap source, please share it with everyone...

> good and cheap source

Pick one. You don't get both. I'm happy to share where you can get real data from.
