Edit: Oops, thought this was a Show HN. Looks pretty clean. If you want a fun feature to build, add tiny sparkline graphs. Maybe pressing z/x/c/v can switch between last hour/day/month/year charts on each stock item. Check out https://github.com/holman/spark https://github.com/holman/spark for how to make graphs with simple character glyphs. I realize my problem with terminal programs like this is that I forget to ever use them. That's why I prefer something like a macOS menubar app that I can toggle to run at startup.

  Many of us don't use macOS, there are plenty of mac apps for stock tracking. My only complaint is it's always going to be 15 minutes behind if you're using public sources, otherwise I love it!

    Yahoo Finance API is real-time for Nasdaq and NYSE. Delayed for most other exchanges though.

  tmux. I have a set of tmux panes which show my current financial status. It's just a couple keypresses away when I'm on the terminal. Things like this, or a terminal weather app, can easily become a quick dashboard using another set of panes. But I practically live in emacs so being on the terminal is natural to me.

  >>> Oops, thought this was a Show HN. <<< If you don't mind, can you explain the difference between this type of Post and a 'Show HN'? Is it that this one was not submitted by the person who built it whereas the requirement of Show HN is that the submitter must be personally involved in the project?

You have no idea how useful this is for me. I have nativefier wrapped yahoo finance/msn money/coinstats etc which are all pretty bloated and this gives me all I need with around 1% overhead. Many thanks.

Nice tool! The ETH-BTC pair is limited by the 2 decimals display, for instance, is this configurable somewhere? It would also be great for crypto traders to source all trading pairs available on coingecko.com, not just the few available on yahoo finance :)

The application uses Yahoo finance to fetch the market information. It is generally delayed by 30 minutes for exchanges like AEX or other european exchanges. What I generally do it query the endpoint in EURONEXT's portal https://live.euronext.com/en/intraday_chart/getDetailedQuoteAjax/FR0000031122-XPAR/full https://live.euronext.com/en/intraday_chart/getDetailedQuote... directly to get the current stock information which is almost real time.

A see a lot of these that use Yahoo Finance API - AFAIU, it was deprecated many years ago and I guess might be in something close to a "forgot to switch off" state. I wonder how much will break when they finally turn it off.

  There's still also a lot of apps around obviously using the Yahoo Finance API. Apps with hundrets of thousands of downloads. I'm curious as well.

    Yes both the iOS and MacOS use yahoo finance api as well. Perhaps Apple is paying the bill here.

      One difference between this and Apple: Apple's apps show the news stories when you pick a stock where Yahoo presumably can get ad revenue. I doubt this gets popular enough to be targeted though.

      - welterde 6y ago
        Sadly the limits for the free tier look too low to even run this CLI ticker application off of it (or is it possible to query more than one symbol in one API call?).
        slig 6y ago
        FWIW, last year I was playing with this API and they were not verifying the key properly: just appended anything at the end of the key and it worked.

This is neat and very cool, just installed it! Since we're talking about API's and finance and not to hijack the thread, does anyone know or recommend an economic calendar REST API feed?
moontear 6y ago
How is it that pretty much all stock trackers / APIs only support US symbols? There are so many stocks out there that don't have a symbol and have an ISIN. Is everybody only trading symbol-based stocks? That seems very limited to me.
teekert 6y ago
Nice! This would be great if it could output HTML, then I'd configure it with the Yaml, make cronjob on my homeserver to auto update and point my browser to it (or more like point it to the nginx container behind my traefik container). But still, this is also very nice, will install tonight. I made something like that myself with the Bittrex API (for crypto) once myself (based on Python and pandas.DataFrame.to_html()), very useful.
rcar1046 6y ago
This is very well done. Didn't realize Yahoo APIs were still live. I made one using IEX. https://stockdaddy.io/samples/dashboard/ https://stockdaddy.io/samples/dashboard/ They offer an excellent API for a very reasonable price and offer it free to people if you're interested in a more comprehensive solution for free. Also, take a look at IEX if you're interested in getting into financial APIs.
kruxigt 6y ago
Is anyone really using any of these stock trackers (including those built in in OSX etc? I think the whole idea is broken. This is why: If you are interested enough to regularly check the price of certain stocks and indices you know that the most important thing is that the shown price is CORRECT. And you know that the most trustworthy way to get a correct price is to go directly to the largest brokers and the largest and most trusted portals like Investing.com and Marketwatch. On the other hand if you don't care that much. Why the hell would you like to have a special application for checking when you could as well go to any of the above?
- Operyl 6y ago
  I play with fake money, in a Discord server with a bot we made and a few friends. Sure, I'm probably not the norm, but I find them useful :).
  - kruxigt 6y ago
    This might be the only real use case haha
- w0m 6y ago
  I feel like it's an excuse to write a CLI app in your favorite language. I dig it; tempted to clone it in python.
  - kruxigt 6y ago
    Nothing wrong with that! :)
  - brundolf 6y ago
    This was my thought too- it seems like a really fun and clean and data-driven coding project, whether it's actually useful or not
- dreamcompiler 6y ago
  If you're a long-hold investor who lives in the terminal, it's perfectly fine. Plus watching GME crash in ASCII is entertaining.

pavlov 6y ago
I remember what the stock market mood was like in early 2000. Everyone breathlessly watching their favorite stocks, IPOs jumping 100%+ on first day of trading, tech companies entering large indexes... This year feels exactly the same as 21 years ago, but people are saying it's different because of Covid, Fed buys, etc. Then again, "this time it's different!" is the rallying cry at the peak of every bubble.
- hpkuarg 6y ago
  "This time it's different!" is also the rallying cry for people trying to time the peak ;-)
- mattnewton 6y ago
  I’ve heard this sentiment call hundreds of tech bubbles since the dotcom boom, and we’ve seen only one in an unrelated sector. I am not saying it isn’t a bubble, just that market enthusiasm tends to look like a bubble but happens all the time without crashing everything.
  - vkou 6y ago
    This is the correct take on it. That kind of analysis has predicted eighteen of the last three bubbles. The problem is that while, say, stocks are frothy, eventually inflation catches up to the froth - so even when the crash happens, you end up better off than if you sat the frothy market out on the sidelines. It doesn't help to be right in the direction of the market, when you're wrong in the timing of it.
    - brewdad 6y ago
      Agreed. As much as I wished I had sold some positions last February when it was clear something big was building in Asia, I am confident that I wouldn't have had the guts to buy back in after the crash and would have missed out on the rebound gains. In the end, I'm probably better off having held and continuing to buy every couple of weeks throughout than trying to time the market swings from COVID.
rayshan 6y ago
Great work! I see that you're using Yahoo Finance data. Yahoo deprecated its API so your data could stop flowing at any time. You can try free services like Alpha Vantage [0] or Google Finance formulas in Google Sheets exposed as an CSV / JSON. Another way is to hook up a freemium service like IEX [1] and ask your users to BYOK - bring your own key. I use IEX for my stock watching browser extension [2] and eat the costs for my users. It's not too bad.

- Glench 6y ago
  Have you considered charging for your extension? I just made https://extensionpay.com https://extensionpay.com which makes it easy to add payments in your extension without needing to run your own server.
  - rayshan 6y ago
    I have! This is timely because Chrome Web Store just killed its payment system. How does this compare to using Stripe out of the box? BTW I think someone was trying to start a browser extension developer guild on HN, can't remember which thread... You should tap into that community.
    - Glench 6y ago
      > How does this compare to using Stripe out of the box? Basically you don't need to run your own server / database / custom Stripe integration code / user management system / custom extension integration, which is annoying to write yourself and costs money to run a server. With ExtensionPay you just add a little code in your extension [open source here](https://github.com/Glench/ExtPay https://github.com/Glench/ExtPay) and register your extension in the web UI. I made it for use in my own extensions :) > BTW I think someone was trying to start a browser extension developer guild on HN, can't remember which thread... You should tap into that community. Cool, I'll check it out, thanks. Any other hints to how I could find it?
DLA 6y ago
Brilliant work. Love it so much. With a black terminal it has a nice pro feel to it. How I miss having a Bloomberg box. Great app. Install was flawless. Love the CLI options. A little reverse text flash upon price change would be amazing. Or a timestamp with the last update time.
elhudy 6y ago
This is nice, but what I would really like to see is a tracker for heavy volume trading. If some hedge fund suddenly purchases 1% of a pharmaceutical company, I want an alert on so I can act on it quickly. Does anyone know of a tool that does this?
- DLA 6y ago
  A Bloomberg Terminal, amazing but $$$$. If a good hedge fund does this then it will be done quietly and across accounts, in dark pools, as a direct trade, or other "off tape" move, often reported later. They're not just going to throw a 1% sized trade in as a limit order for you to see, so the "act on it quickly" part is not as easy as you may think. (Former professional trader)
  - elhudy 6y ago
    I actually know some amateur traders who act on such things in a discord chat I'm in. They have their own algorithm that runs against market data but wont share it. It seems easy enough - when lots of volume moves in a relatively short time period, it shouldn't matter who the purchaser is. An algorithm should be able to catch on. Thoughts?

belgianpi 6y ago

gpresot 6y ago
Really great app. One minor issue I have with it is that when you sort alphabetically (by ticker symbol), the watchlist and the portfolio get mixed together, which is counter-intuitive and a bit unfriendly to the eyes. I would expect it to sort alphabetically but grouping separately the watchlist elements and the portfolio elements.

Awesome! Anyone know a similar project in Python?

This is neat and very cool, just installed it! Since we're talking about API's and finance and not to hijack the thread, does anyone know or recommend an economic calendar REST API feed?

How is it that pretty much all stock trackers / APIs only support US symbols? There are so many stocks out there that don't have a symbol and have an ISIN. Is everybody only trading symbol-based stocks? That seems very limited to me.

Nice! This would be great if it could output HTML, then I'd configure it with the Yaml, make cronjob on my homeserver to auto update and point my browser to it (or more like point it to the nginx container behind my traefik container). But still, this is also very nice, will install tonight. I made something like that myself with the Bittrex API (for crypto) once myself (based on Python and pandas.DataFrame.to_html()), very useful.

This is very well done. Didn't realize Yahoo APIs were still live. I made one using IEX. https://stockdaddy.io/samples/dashboard/ https://stockdaddy.io/samples/dashboard/ They offer an excellent API for a very reasonable price and offer it free to people if you're interested in a more comprehensive solution for free. Also, take a look at IEX if you're interested in getting into financial APIs.

Is anyone really using any of these stock trackers (including those built in in OSX etc? I think the whole idea is broken. This is why: If you are interested enough to regularly check the price of certain stocks and indices you know that the most important thing is that the shown price is CORRECT. And you know that the most trustworthy way to get a correct price is to go directly to the largest brokers and the largest and most trusted portals like Investing.com and Marketwatch. On the other hand if you don't care that much. Why the hell would you like to have a special application for checking when you could as well go to any of the above?

I play with fake money, in a Discord server with a bot we made and a few friends. Sure, I'm probably not the norm, but I find them useful :).

  This might be the only real use case haha

I feel like it's an excuse to write a CLI app in your favorite language. I dig it; tempted to clone it in python.
- kruxigt 6y ago
  Nothing wrong with that! :)

  This was my thought too- it seems like a really fun and clean and data-driven coding project, whether it's actually useful or not

If you're a long-hold investor who lives in the terminal, it's perfectly fine. Plus watching GME crash in ASCII is entertaining.

I remember what the stock market mood was like in early 2000. Everyone breathlessly watching their favorite stocks, IPOs jumping 100%+ on first day of trading, tech companies entering large indexes... This year feels exactly the same as 21 years ago, but people are saying it's different because of Covid, Fed buys, etc. Then again, "this time it's different!" is the rallying cry at the peak of every bubble.

hpkuarg 6y ago
"This time it's different!" is also the rallying cry for people trying to time the peak ;-)
mattnewton 6y ago
I’ve heard this sentiment call hundreds of tech bubbles since the dotcom boom, and we’ve seen only one in an unrelated sector. I am not saying it isn’t a bubble, just that market enthusiasm tends to look like a bubble but happens all the time without crashing everything.
- vkou 6y ago
  This is the correct take on it. That kind of analysis has predicted eighteen of the last three bubbles. The problem is that while, say, stocks are frothy, eventually inflation catches up to the froth - so even when the crash happens, you end up better off than if you sat the frothy market out on the sidelines. It doesn't help to be right in the direction of the market, when you're wrong in the timing of it.
  - brewdad 6y ago
    Agreed. As much as I wished I had sold some positions last February when it was clear something big was building in Asia, I am confident that I wouldn't have had the guts to buy back in after the crash and would have missed out on the rebound gains. In the end, I'm probably better off having held and continuing to buy every couple of weeks throughout than trying to time the market swings from COVID.

Great work! I see that you're using Yahoo Finance data. Yahoo deprecated its API so your data could stop flowing at any time. You can try free services like Alpha Vantage [0] or Google Finance formulas in Google Sheets exposed as an CSV / JSON. Another way is to hook up a freemium service like IEX [1] and ask your users to BYOK - bring your own key. I use IEX for my stock watching browser extension [2] and eat the costs for my users. It's not too bad.

Have you considered charging for your extension? I just made https://extensionpay.com https://extensionpay.com which makes it easy to add payments in your extension without needing to run your own server.
- rayshan 6y ago
  I have! This is timely because Chrome Web Store just killed its payment system. How does this compare to using Stripe out of the box? BTW I think someone was trying to start a browser extension developer guild on HN, can't remember which thread... You should tap into that community.
  - Glench 6y ago
    > How does this compare to using Stripe out of the box? Basically you don't need to run your own server / database / custom Stripe integration code / user management system / custom extension integration, which is annoying to write yourself and costs money to run a server. With ExtensionPay you just add a little code in your extension [open source here](https://github.com/Glench/ExtPay https://github.com/Glench/ExtPay) and register your extension in the web UI. I made it for use in my own extensions :) > BTW I think someone was trying to start a browser extension developer guild on HN, can't remember which thread... You should tap into that community. Cool, I'll check it out, thanks. Any other hints to how I could find it?

Brilliant work. Love it so much. With a black terminal it has a nice pro feel to it. How I miss having a Bloomberg box. Great app. Install was flawless. Love the CLI options. A little reverse text flash upon price change would be amazing. Or a timestamp with the last update time.

elhudy 6y ago

This is nice, but what I would really like to see is a tracker for heavy volume trading. If some hedge fund suddenly purchases 1% of a pharmaceutical company, I want an alert on so I can act on it quickly. Does anyone know of a tool that does this?

DLA 6y ago
A Bloomberg Terminal, amazing but $$$$. If a good hedge fund does this then it will be done quietly and across accounts, in dark pools, as a direct trade, or other "off tape" move, often reported later. They're not just going to throw a 1% sized trade in as a limit order for you to see, so the "act on it quickly" part is not as easy as you may think. (Former professional trader)
- elhudy 6y ago
  I actually know some amateur traders who act on such things in a discord chat I'm in. They have their own algorithm that runs against market data but wont share it. It seems easy enough - when lots of volume moves in a relatively short time period, it shouldn't matter who the purchaser is. An algorithm should be able to catch on. Thoughts?

this is fantastic. thanks.

Really great app. One minor issue I have with it is that when you sort alphabetically (by ticker symbol), the watchlist and the portfolio get mixed together, which is counter-intuitive and a bit unfriendly to the eyes. I would expect it to sort alphabetically but grouping separately the watchlist elements and the portfolio elements.
