Where is the market data (price, volume, etc) from? All open source projects related to stocks seem to use Yahoo quotes, which is essentially abandoned and not supported at all. No SLA or any indication of long term survival.

I found Alpaca[1] which looks decent in terms of a stock API and their upstream data provider Polygon.io[2] which looks even better but costs $199/mo for essentially per tick market data.

According to the docs it uses https://www.alphavantage.co/

He just wanted to push his service. HN comment section has been unbearable recently with the substantial increase of people doing this. It has always been present but now it is almost reaching the point of making the comment section worthless.

I'm OK with it so long as it's something on GitHub, useful, and you can drop in replace it.

I am OK if it is something directly relevant to the topic and it is presented in a direct manner, but no, 99% of the time it is some disingenuous thing like this: "Hey guys you are talking about nuclear engineering, that made me wonder how fishes in my zone would be affected by a nearby nuclear plant . I use allmyfishes.com which seems to be a great site detailing all the fishes in the US, there is a free tier and good paid plans. _disclaimer_ I founded allmyfishes.com"

And it just happened again, in this same thread:

I think we need some sort of AI tool to identify these cases. I read a review on findbssales.io which says it could do exactly this, with a good payment model based on API calls.

Disclaimer, I built findbssales.io

findbssales.io is down.

I won’t mention that website, but FYI I built it and I have no idea who posted that comment.

I don't think nodesocket is affiliated with the sites he linked, nor I find any links between the two?

For real, this has been a big problem for a lot of people. So I built a real time comment pruning algorithm service that lets you browse HN with only quality comments. Subscribe today!

Pushing your own product has been standard and encouraged practice at HN since the beginning. This is an incubator site!

Even if you are posting a fake review as a third person?

Who just wanted to push this service? OP or sevencolors?

Either way, as a counterweight to all the conspiracy theory nonsense on the web, I have been making an effort to not assume I know people’s hidden intentions. I’d like to invite you to join me in that.

Nigerian princes must really love you.

Yeah im just as lost as you. Im not really sure who is pushing what service that is their own... either way, I did find all the links relevant, and worthwhile knowing about..... shrug

There are quite a lot of comments that make it to the top which say, "That's nice, I made this similar thing which is really interesting, here's a <link>." Followed by a big thread about their thing.

I don't mind those comments so much, as they can lead to good stuff, but I do mind them derailing the main thread when they are upvoted. So, I often downvote them in retaliation.

What is this low-quality cynicism? Why do you think that it's his service?

Alpaca is primarily for trading.

They were using Polygon for data, but if I recall correctly, I believe seeing an email or such that they're going to roll out their own data and discontinue the Polygon "bridge".
