Not OP, but I am in charge of engineering and operating a high-performance quantitative algorithm engine at my company and I can wholeheartedly recommend https://polygon.io.

We continously pull their whole dataset in one minute intervals as well as receive real-time feeds for the whole universe over websockets and they haven't complained once.

I am going to say not if you’re running high $$$ boxes. I would not rely on Polygon for anything beyond PA.

I was talking about PA. They have proven themselves very reliable for it so far.

Fundamentals and other information is being pulled directly off NASDAQ etc, of course. Polygon does not offer a lot of data in these regards.

Realistically for $$$ systems you want to have more than one source for every datatype anyway and then aggregate the data yourself.

PA?

"personal account" - vs. the fund(s) an investor may work on as part of their day job

[Mo3]

Oh.. I meant price action. But I guess it’s true for both!

[melony]

How accurate are their fundamentals calculations?

Why?
