Show HN: Trader News – Hacker News for Finance

Hacker News helps me stay in touch with the world of technology without putting in extensive web browsing work, and I love it for that reason. I am interested in financial markets and wanted a “Hacker News for finance”, but Googling produced surprisingly poor results. So I forked the great HN clone, shark [1], and added some market focused twists.

The result is: https://tradernews.fyi

Trader News is the Hacker News interface you are familiar with, with a difference. Above the article area is a live feed (up to a ~30 min delay) of market data. I show the major indexes and every company within them. E.g click on Nasdaq-100 to see how the index performing, and then scroll the list of companies and click on META to get more detail on its specific performance (and links to Yahoo Finance + it’s investor relations). This gives you a single place to read finance related articles and stay in touch with the markets.

The CSS for Trader News is linked to global market performance. On days when stocks are down, Trader News is red. On days where stocks are up, Trader News is green.

I have an agent running a 24 hour cron job to research articles and post them to the site to keep it a stimulating place to read. I will tone this down if user submissions pick up. If there are sources you think I should include, please leave a comment.

I also added a basic “chat” panel with polling every 30 seconds for casual market related chat.

It’s open source and I’m very interested in feature pull requests. The code is available here:

Public anonymised analytics are available with a 15 min delay here:

Very cool! Where do you get the market data from? I am building something with financial data as well, and couldn't find any inexpensive source I was allowed to republish, so I ended up using IEX.

I have a 30 min cycle of polling yahoo finance every 2s, one per share/index every 2 sec if that makes sense

I see, so about 900 symbols per 30 minutes. IEX puts out one file per trading day with every trade on IEX, so you get the last trade for about 8,5k US symbols in one download the next day ~12GB compressed though. Has Yahoo ever throttled you at that rate?

Having some /new messages show at the bottom of the front page is pretty good. @dang => you could maybe consider this in HN?

Congrats on shipping! I’ve actually been thinking about a somewhat adjacent problem, but more geared towards fundamentals investors. However the caveat with fundamentals though is that they don't change that often.

I feel the UI is pretty cluttered and noisy. Especially the fonts below the charts are too small to read.

Thanks for the feedback. Yeah agree re that. Will update soon.

What does that mean?

It means the exposure of being in HN front page usually causes a sudden spike of visits, and the increased traffic was too much for the server so the service is down for new visitors.
